Sonoff RF Bridge w/ MQTT & Home Assistant 

like the features, setup was difficult for some of my devices (August Door lock, ru-vid.comUgkxhB5YOMNj04GuoAosExygP4cH-dKeb4aB Bose speaker)... but all switches and outlets (5), thermostat, tankless water heater. Unfortunately all I can do is turn on/off Bose. It doesn't support volume or changing channels, but I believe that is due to the particular speaker I have.... Worth getting if you already have other devices to use it with... I don't sit around and ask Alexa questions much so that doesn't really matter to me....

UPDATE: if you have trouble with the OpenMQTTGateway asking for a password try: your_password Big thanks to Christos V. for finding the solution!

Oh man, this is a great video. Makes my video for this week look silly (also a 433mhz device)!

I cant express my appreciation enough. Gold

I have had my sonoff smart home devices setup ( standard,no flashing) for about a year now.....working great ! S31 switches ,light switches,water sensor,door contacts.......all flawless

I was using tasmota on one of these bridges & had the pir & door sensors set up. I went with xiaomi sensors in the end. Door states were reported correctly & I added temp & humidity sensors to go with it. Worked out well. Have automated all the hvac in my home to turn off if there is a door or window open, with report of which door/window it is. Everything turns off in the kids room, if there is no one in there. That alone will save me thousands ;-) For Tasmota on the rf bridge & setting up the sensors, the data thats reported through mqtt is nested json data (apparently) See "Integrating RF devices with sonoff bridge on tasmota firmware" on the home assistant community pages. "bukurat" gives the solution that I used, which worked. I had the pir sensor set up the same way, with an automation that turned it off after 5 seconds. Happy Hassing ;-)

Hi! This worked perfect once I decided to follow your steps EXACTLY as described :) , with a couple of notes, though: - you said: "once this is successful, and I'm sure it will be, on your first try (...) then get out your phone and look for a wifi network.." Actually, there's no OpenMQTTGateway network available at this point. I assumed you disconnect the Sonoff RF Bridge, put its switch back to "ON" and then plug in a power adapter to power it on. Correct? At least this is how it worked for me. - the topic seems to be home/OpenMQTTGateway/SRFBtoMQTT (without the last " / " as captioned on the video) and seems to be case sensitive! When all is up and running I get the messages on this topic (with MQTTlens) but it takes about three seconds from the time I activate/deactivate the magnetic switch until the RF_LED on the Sonoff RF Bridge blinks and the message pops up in MQTTlens. Is that expected? I should add that I first tried to flash from command line with esptool.py (first erasing and then esptool.py --port COM4 write_flash -fs 1MB -fm dout 0x0 OpenMQTTGateway_1.bin ). This did not work! I mean the flashing was successful but I got other problems, different ones depending on the bin (the one you linked and others downloaded from the OMG page): - with some versions I did not get the WiFi setup page - with another version I would get that setup page each time I powered the Sonoff RF Bridge up (like it forgot the settings or something). For anyone trying this I highly recommend using the ESPEasy the way you described it. Thank you for this tutorial!

Thank you for your this. I've been using this for about 7 months and it just works reliably. I went through the zwave pain and I now only have 2 legacy zwave ssnsors. Not only are they extortionate in pricing but the whole set up is short of "temperamental" to use an euphemism I definitely recommend this solution and as you stated it can do many other things such as ir BT etc (Not with sonoff).

Hi DrZzs First up great videos. Thought i would help out with tasmotising Sonoff RF Bridge. This worked for me. Flash the Sonoff RF with tasmota in the usual fashion. logg onto Sonoff Rf and do the usual Network and MQTT configurations and change to Bridge Module. Save configurations . Then in the console place Sonoff RF in learn mode. enter 'RfKey* 2' (replace * with the number 1 to 16 being the unique number for the sensor that is to be linked with the sonoff Rf. should hear two beeps from sonoff rf then sync your sensor. Then add the following to configuration.yaml #add to configuration.yaml binary_sensor: - platform: mqtt alias: "Movement Upstairs" name: "Movement Upstairs" payload_on: "1" payload_off: "key1_off" state_topic: "tele/sonoff/RESULT" value_template: '{{ value_json.RfReceived.RfKey }}' optimistic: false qos: 1 retain: false # note that payload_on: "1" is a reference to the sensor that you synced with the sonoff rf and can be number between 1 to 16 Add the following in the automation.yaml #automation.yaml - id: reset rfkey1 (movement upstairs) alias: Reset RF bridge RfKey1 hide_entity: true trigger: - platform: state entity_id: binary_sensor.movement_upstairs to: 'on' for: seconds: 5 action: - service: mqtt.publish data: topic: tele/sonoff/RESULT payload: "key1_off" # the following will turn a light on when movement is triggered. - id: turn_on_movement alias: Turn on light when there is movement initial_state: 'off' trigger: - platform: state entity_id: binary_sensor.movement_upstairs to: 'on' action: - service: homeassistant.turn_on entity_id: light.stairs_lights Hope this helps

Hi, Thank you for the wonderful information. I also started automating my home setup last year and figured out using the sonoff door sensors that they create only time alarm trigger instead of open and close state trigger. I wanted my balcony lights to Turn ON as the door opens and Turn OFF when we close the door and through the Sonoff door sensor, it certainly was not turning OFF the lights. So I got a Sonoff PIR sensor and stuck it behind the door wall and set the PIR sensor alarm to Turn OFF the balcony light. So the PIR sensor triggers an alarm if I come in front to open the door, which will trigger an alarm to turn OFF the already OFF balcony light and then the door sensor will trigger the Balcony light to Turn ON and when I enter the room and close the door, the sensor again Turns OFF the door light. The only catch here is the placement of the PIR sensor, as initially I stuck the sensor at the edge of the door and it used to trigger 2 alarms, one seeing me approaching the door and then after opening the door, it triggered another alarm turning OFF the balcony light as it saw the door coming it's way. So I moved the PIR Sensor to the middle of the door and now it's works perfectly as it probably senses myself approaching the door and the door opening under the same alarm trigger. It's probably not the perfect solution and works only 8 out of 10 times correctly. But considering the cheap price of Sonoff, I really won't complain for the 2 times it messes up.

Great and interesting video ! We're lucky to have you around Dr. Zzs ! Where would we be without you ;)

Another great video as always. I flashed my bridge with Tasmota and am using the door sensors. I send a push notification (and to my google home) when a door is opened...basically an alert if my kid runs out of the house. In Node-Red I take the payload, parse it to JSON, then grab the Payload.RfReceived.Data value to determine which sensor it came from. Works like a charm, and might get you back to Tasmota!

Amazing! this is going to make my migration from LightWaveRF to Ikea Tradfri so much simpler (and cheaper)! Thank you!

Great tutorial and really helps with my RFBridge deciphering the MQTT messages using Espurna.

I would really l enjoy more RF videos. There are so many super cheap sensors and devices out there.

Great video, keep ´em coming :-) To make a door closed sensor, I have replaced the Normally-Open (NO) reed switch with a Normally-Closed (NC) in a Sonoff DW1 That way I can use two door sensors to detect the state of a door. The NC to detect the opening of the door and NO to detect it being closed again.

I thought my life was fun and simple until I saw this video. haha. lol. I am about to embark on a long and troublesome journey down the rabbit hole....cool video btw. :)

hi, I have created the same single code sensor , using Node Red, publishing to MQTT Topic. I works great. Same yaml config used.

Good videos, I like the way you explain everything. Please keep them coming!

Thank you for great job! I have made a pretty good automation system in my home based on you videos practically with zero knowledge in linux and yaml in the begining. One observation: instead of making automation to revert sensor state to 'off' we can add 'off_delay' setting in configuration.yaml

New to this stuff here, struggling with Home Assistant and Tasmota for a week now, but I'm starting to get the grasp of it. You know what is very hard to find for newbies like me? Good conceptual information about how things work, how Home Assistant is organized and so on. Almost all videos and articles are too specific about a particular subject. Maybe you can fill this gap :) I'm using Tasmota with the Sonoff RF Bridge, and this is what I'm doing to configure it in Home Assistant: binary_sensor: - platform: mqtt name: "PIR Garage 1" payload_on: "XXXX" payload_off: "XXXX_off" device_class: motion state_topic: "tele/srf/RESULT" value_template: '{{ value_json.RfReceived.Data }}' retain: 'true' Where XXXX is a value that I can read using the "Console" button in the Tasmotized RF Bridge web interface. I'm using automation to send an MQTT message to "turn off" this binary sensor, same as you are doing.

Amazing !! . thx a lot .. already ordered one of those kits for myself . As always you are awesome

Thank you for your tutorial tutorials and, although novice, I put the firmware tasmota in sonoff RF and implement an idea of yours from another tutorial to rescue data. Here I leave it and as always, thanks binary_sensor: #Sensor de movimiento - platform: mqtt name: "Sensor Movimiento" state_topic: "tele/sonoff_RF/RESULT" qos: 1 payload_on: "D3AE4E" payload_off: "D3AE4Eoff" value_template: "{{ value_json.RfReceived.Data}}" retain: false device_class: motion

Just what I need it. Burned my Sonoff RF last night waiting for the new one. I am going to test my Paradox alarm system with this. I will post the result. Just making it more challenging I use your Automation to my office to turn off the lamp and the LED strip switch but some times I leave the B1 lamp on in color mode. So how to avoid turn off when the lamp is in colour mode and turn it off when it is in white mode? Thank you and keep up the great job

God I thought the bridge was much bigger before this video and was surprised when he held it up

I wonder if this will work with Tesla HomeLink to open an electric gate? Gate has a Sonoff SV set up with D1 Mini WiFi keys but this system needs something that is compatible with Homelink.

oh oh, I've just found there is an Hassio option to avoid the automation.yaml configuration to reset the SINGLE STATE BINARY SENSOR back to off. Here is: "off_delay " (integer)(Optional)For sensors that only sends On state updates, this variable sets a delay in seconds after which the sensor state will be updated back to Off. I used it, in this way into configuration.yaml: - platform: mqtt name: "Porta Terrazzo" state_topic: "tele/bridge-1/RESULT" value_template: '{{ value_json.RfReceived.RfKey }}' payload_on: "7" off_delay: 30 device_class: door qos: 1 when the binary sensor went ON it will be backed to off after 30 secs and NO Automation is requested to do the reset job.

You are the best, DrZzs: Thanks for the great video!

Hi Sir, Do you have an updated video on doing the same thing using the sonoff bridge flashed with tasmota and portich?

What do you think, wich software is better for DOOYABLINDS. OpenMQTTGateway or Tasmota with the Portisch firmware? I will control the bilinds in HomeAssistant. I hope it´s possible to get a state in % or somthing linke that.

Another amazing video! This is getting better day by day!

hi, thanks for all your great videos. floating head cracks me up every time. ive had the rf bridge up and running with tasmota for about 6 months. took me ages to get my head around the decoding of the json. one problem was that tasmota sent hex over mqtt from the bridge but needed dec to activate rf relays and sockets. i changed a few lines of code around in tasmota to make this work. i never forked it and put a pull request in github but i may go back and see if i can remember what i did. again thanks for all your help with home assistant

Hi Dr ZZE please i tried to flase my sonoff bridge with this bin but went it's run i can't fine the wifi host

Thanks so much DrZzs, another really informative vid!

Hi Im John from Italy.... I'm a big fan. I am looking for a woreless battery powered external pir motion sensor that can trigger my external flood lights as a traditional sensor but I would like to create some routines to control my flood lights through a sonoff basic. Any idea's? The basic idea is for security purposes or to light up the surroundings at my arrival at night through a voice command or IFTT geofencing. Thanks and continue making great content

U can also use node red buy searching the payload for a particular code and publishing a different mqtt topic with a different payload. Your videos are amaing. i always look forward to them please keep on making them

Awesome video as always. Keep them coming! thanks a lot!

Fantastic video, thank you. I've been able to replicate your schema on a Sonoff RF bridge flashed with Tasmota, configured on Hassio, with the following setup: on configuration.yaml file - platform: mqtt name: "Porta Terrazzo" state_topic: "tele/bridge-1/RESULT" value_template: '{{ value_json.RfReceived.RfKey }}' payload_on: "7" payload_off: "700" device_class: door retain: false qos: 1 optimistic: false on automation.yaml file - id: Reset Porta Terrazzo alias: "Reset Porta Terrazzo" hide_entity: true initial_state: 'on' trigger: - platform: state entity_id: binary_sensor.porta_terrazzo to: 'on' for: seconds: 30 action: - service: mqtt.publish data: topic: tele/bridge-1/RESULT payload: '{"RfReceived":{"RfKey": 700}}' as you can see I used numeric values for payload_on and payload_off (7 & 700) the reset automation starts after 30secs (instead of 5 secs) and activates the service mqtt.pub publishing the same topic with a short form of payload '{"RfReceived":{"RfKey": 700}}' still detectable by the value_template ( {{ value_json.RfReceived.RfKey }}' ) to reset the binary sensor. I've been able to configure 2 PIRS and 3 door/window sensors with a single state change (open).

Hi Dr I have Broadlink RF pro. I heard that Sonoff Basic RF is not compatible with Broadlink frequency so I ordered Sonoff RF Bridge. I have different types of down lights installed in my home (not my doing). Those come in different sizes and also use different power (12v, 16v with transofrmers and 230v). There are some downlights that are wifi based including hue range. However unlike normal lights where down lights are installed there are about 4-5 of them in each room. So If I am to get wifi based down lighrs I would be clogging my mesh network further. As such I am planning to add Sonoff RF basics for each downlight and then use Sonoff Bridge to control them. In that way I do not need to change the existing bulbs or power controllers and just need to add a soffbasic RF to the circuit which is very easy to do. My question is have you played with Sonoff Basic RF and can I easily on/off with the Bridge which mimic turning on off down lights via switch. Thanks

On my Linux Mint system, it know the battery status of my AA mouse battery. It is at 70% right now. Is there a way to get the battery state of these RF devices?

Another GREAT video in the can!

The mailman just delivered my RF Bridge, but this one is a Version 2.0. It'll flash successfully, but cannot connect to WiFi through OpenMQTTGateway ... even using the password "your_password". I flashed it with both the bin_1 and the bin_2 but no luck. Guess I'll wait for your Tasmota video for this RF Bridge. Wanted you to know about the V2.0 incompatibility. Been loving your videos since December - keep 'em coming DrZZs!

Hi Dr Zzs, First of all, great blogs / tutorials! I have learned a lot and because of you I changed to HA. I have only a question: I have Tasmotized my Sonoff bridge. I receive signals and working fine for that. However, I’m wondering if you also have a blog how to send 433mhz codes, to activate for example an 433mhz siren. HA greetings, Tedzor!

OMG is great but you should try Espurna it is really good and has a web interface as well

Hi! I got the "GS-WDS07 Wireless Door Magnetic Strip" from banggood which actually transmit two separate codes for close and open. So that is nice. But there's another problem: if HA is restarted it'll show the doors as "closed". How do I make HA remember the last status? Better yet: is there a way to request the status from these switches? Or hack them into sending their status at intervals... Thanks!

Great videos. Would you be able to make a video with the same parts but with openHAB. I have followed a lot of videos but i cant seem to get the door icon in the Control page to open or close.

great video! but i seem to have run into a strange problem, i am only able to get message as 0 for a door sensor on OMG but when I add a PIR sensor to the OMG, both the sensors start to send the same message information. thanks please help

Have you tried the Xiaomi Gateway? Very cheap sensors and very reliable. I'm in the US and bought the gateway which came with the China->US power adapter and I couldn't be happier.

Has Tasmota improved in regard to messaging or would you still recommend openmqttgateway?

hi Dr, thks for the video. Just wondering do i still us the ewelink to add devices to the RF bridge AFTER flashing the bridge? or we have to add all the devices first before flashing? Thanks in advance. Jacky

I had similar problems with tasmota with ir receiver. You need to recompile it to support longer mqtt messages. The default mqtt size is too short for this kind of messages and corrupt them.

Thank's for this helping videos!

I offset the door sensor on my garage door so that you get a message when the door opens (sensor passes by) and closes (sensor passes by again). It is not bullet proof, but at least you get a 2nd message.

So you're using a gateway to convert RF to MQTT. Can't we skip the gateway and simply have an RF receiver on the Rasperry?

Do you know of a solution that would work like this for 319.5 MHZ sensors from a QOLSYS IQ 2 panel? Love these videos. The WLED videos helped a ton! Keep up the great work.

Superb ji with the fake payload

amazing stuff! thanks a lot.

Can the sonooff rf bridge be used with anything that runs on 433MHz like for example a cheap wireless doorbell?

I'd be interested to see this bridge used to control an automatic garage door or gate

Great video, thank you.

if you cant find the wifi network after flashing just flash tasmota bin and then flash the openMqttGateway... work for me !

Thanks for great videos DrZzs! I have had problem to find sonoff devices (S20, S26, ..RF bridge at the latest) on wifi after flash in every case except for a TH10. Have tried both ESP Easy and Tasmota. The flash seems to be successful but then nothing. With Wemos D1, success every time. Never any problems. Any advice?

Where do you host home assistant? On raspberry pi? Do you trust its reliability?

I've had the RF bridge and some sensors for a while now and it runs on tasmota. sonoff POW and RF bridge sends its important messages through Json This is how i extract the code RF bridge sends through Tastmota - platform: mqtt name: "Motion" state_topic: "/home/rf-bridge/tele/RESULT" value_template: "{{ value_json.RfReceived.Data }}"

i have got a few 12v23A door sensors but the battery was empty after a year i wonder if i replace them for 3V (CR2032) it would last longer? great video BTW. keep it up!

Hi everyone. I´m new with Sonoff. Does anyone know how many PIR or magnetic sensors may be connected to an RF Bridge ? I need to connect more than 64 sensors. I´ve read limit is 16. Maybe with Tasmota or another firmware, limit may be higher. Thanks !

I read all the reviews of the Sonoff RF bridge and they complain that it only supports 4 devices. But I can’t figure out if that’s a limit in EWeLink itself or the hardware? When you flash it with new firmware are you able to support more than 4 devices? If so what is the limit before it fails? I’d like to setup what you show in the video but I don’t want to waste my time if it doesn’t scale well.

Good video, thanks. Any chance you could do a video on IR blasters and HA?

Your audio is good again!

Can you help me to send rf-commands using rf bridge through Home Assistant? Nobody rewieved this ability...

DrZzz do you think if I use a 433 RF Transmitter Arduino module to tramsmit sensor data (from temperature sensor for example), it could be read via the Sonoff bridge? The idea is to build a DYI low power temperature sensor with something like Adafruit Trinket + Temperature Sensor + 433 RF Emitter to transmit temperature to Sonoff Bridge and then to Home Assistan.

Will Broadlink RM Pro read these sensors (double code ones) ? Or just the Sonoff RF hub is capable of this?

Hi there, I had a problem with some single code Window/Door Sensors which I solved by soldering 2 pads together on the PCB. Now, the sensor sends one separate code for on and one for off. I cannot find any internal photos of the DW1 Sensor that you are showing in your video, but if you use one sensor as a test subject and poke around some empty contact points, and at the same time bring close/away the magnet, just look at what codes are displayed in the MQTT sub topic.

It did not work as I expected, but thanks good vid

Great Video! Easy to follow also, even if I haven't got the stuff yet I can already Imagine doing it. :) By the way Dr. Zzs? May I request if you can cover sonoff POW on how to tasmotize it and use it's sensor? TIA!

thanks doc. I will get the bridge with out the sensors. for the other one you showed ($10) can be used with out automation to indicate if the door is open or cloased ? i believe this bridge would work with the 433mhz fan controllers. not to mention the sonoff RF. not sure if it will works with the new US touch switch that does include the 315mhz radio. Doc, since you have the touch switch please test and let us know if it works on the US touch switch.

As you mentioned in today's RU-vid live can you please post link for other dot Bin files so that I can give a try with other files & verify if those work for me. Thanks in advance

Awesome, as always ! For door sensors (that give the current state) what do you prefer RF, Zigbee or Zwave ???

What's the Range of the Rf devices? I live in a big house. and therefore I got a lot of ZigBee and z-wave stuff. but at the price point, the RF stuff comes at it made me interested. then again if I need to have multiple bridges like you do with IR I think I might just pass on the RF stuff what you're experience with this?

you are my hero ... TQ ...

After flashing Sonoff Bridge will also suport more devices to be added to same bridge ? Initially support only 4 and in case you need more have to buy another bridge .

I used this one: espurna-1.12.6-itead-sonoff-rfbridge.bin. When I did setup the mqtt user and password it added automatically in homeassisant without modification to the config file

ow control 433mhz autlets with sonoff RF bridge ower home assistant?

Nice videos as always! Is the Sonoff RF Bridge an alternative to the popular Broadlink RM Pro?

Hi, having trouble with this. I just get a command window that cycles through a few attempts and the flash failed. "trying to connect". Ive followed your instructions but im stuck. What am i doing wrong?

I once shook the hand of Theo Tasmota!

I have a GE Simon XT alarm that I was using before I set up HomeAssistant. I am going to order the RF Bridge and try and use the sensors from that with HA through the bridge. - Has anyone else used this RF Bridge with existing alarm sensors yet?

A quick (not complettly perfect) solution to the "Sonoff DW1 one code problem": Have two DW1 sensors mounted exactly over each other on the door/window frame. Have a magnet on the door leaf aligned to the bottom DW1. If the door is open, both DW1 pulls, first the lower next the upper. Program that in this case the upper DW1 state change will be ignored. (This is the not exact part of this solution.) The lower DW1 status change shows the opened state of the door. When the door is closed, only the upper DW1 status will change. This will be the door locked status. (But the really exact solution a sensor firing two sates.)

Hey Dr Zzs, help me! how can I link tasmotized sonoff basic to eWelink?

Hey all. Is there anyone who can tell me if you need to flash a sonoff Dw-2 RF door/window sensor in order to receive codes with an rf sniffer for connected to raspberry pi? @drzzs

Great video! What is the range of the RF bridge? Can you get away with using just one for an entire house?

What's inside the DW1 sensor? Maybe a NO and NC reed switch can be used on the one sensor with a firmware mod?

Thanks a million...as usual. My Tas flashed RF bridge has been a paperweight for a few weeks now. Was up and running, but I could never get the RFkey commands right to retrieve the mqtt codes for commands. So I gave up and waited on your video. ;-) Question: What is the total number of sensors per bridge that can be added? In eWelink app you can only add 4 alarm type sensors per rf bridge. Hence the reason I am using 3 of them for basic coverage...ummm...2 now, cuz I killed one with Tas. LOL

Great video! Ordering one tonight! Can it send 433MHz tho? Would be cool for those cheap Switchplugs. Also, for the door sensor, perhaps a switch? On signal: if (door is open): door = closed. else door = open

I use espurna firmware on sonoff bridge .. please give a try... is very good and easy

DrZzs, i just flashed it.. and i dont have any other wifi appearing... can you help? THanks. Marc.

Hi. Great videos. I’d like your opinion in how I should invest in devices because I only have one RF device that my garage door. Should I buy the only RF motion and window sensors? Thanks.

i got a 433mhz on off switch, i cant figure out how to set it up to turn on a light in HA, i got the sonoff rf setup in binary sensors, i tried this automation not working alias: test 433 trigger: - entity_id: binary_sensor.433_kontakt platform: state to: 'ON' payload: 13259682 condition: [] action: - data: entity_id: switch.akvarie_lys service: switch.turn_on

Hi aden . I have just got the bridge and installed/ flashed the bridge with the open mqtt. I cannot see the payload after I have set up the settings etc. Anyone have this experience ?

Does your PIR2 work fine? Mine shows an inconsistent behavior, sometimes I can dance in front of it and the thing doesn't detect any motion.
