Sonoff RF Bridge with Tasmota 

Thanks!

Thanks! That's why we do it. :)

Excellent!

Excellent! I love my RF bridge. It has been super reliable. Hope it works for your siren!

ya, I hate funky sized batteries. And if you're going to sell something with such a screwy sized battery, add $2 to the price and include a battery please! Anyway, glad you got it!

Awesome! Thanks again to you for pointing me in the right direction. Sounds like you are the master of the RF Bridge. I'll be coming to you for any future questions :) Are you on Discord?

ha! i wouldn't say master. Ive been programming arduino and RF for many years so i can understand most of how the tasmota firmware works. i cant help but think that tasmota and home assistant is the best thing since sliced bread. my discord number is #1361.

Hey - hope you can help; when i restart HA after a config change, the sensors on my RF Bridge all go into a closed state even though they are open. Also, my cover.garage goes into a unknown state as i have a RF reed sensor as well. As soon as i open any of the sensors it gets back on track again. Seems like the RF bridge is not retaining the last state per device. any suggestions? Thank you

Hi. The rf bridge is not smart enough to retain the states of any rf devices it controls or monitors. Home assistant can do this and if you look up recorder logbook and history there are some setting to be able to reload previous states of all entities. Remember RF is only one way communication so the states are assumed based on the last received communication. If a communication is missed then the states can become out of sync.

This is perfect thanks, final piece in replacing my dead RMPro with one of these. Fraction of the price and so easy to learn codes compared to the pot luck disaster with the RMPro. As usual, far more complicated to read about than do. @DrZzs, tried your EZ flash technique for the first time with this, and again, so simple, thanks.

Mersi gagiule :-)

Good luck!

ha! glad to hear you got it working. I love the fridge one. Especially with the automation to announce that it's open and someone needs to close it. I hope the videos work. Sometimes I make mistakes or forget steps or things change. I'll keep trying to do good stuff that works :)

DrZzs The big problem that I had was reported by others. Termite would not work. While fiddling around , I broke a wire . My programming setup was a kludge so I rebuild it. Anyway I read the comments and realized a lot of others had the same problem. So you might state that we read the comments before we start implementing the video. This is not a problem with the videos. Thanks again for your fabulous efforts.

Thanks!Good feedback too. It's always a little hard to know what to repeat and what I can skip over.

Glad you posted this! I forgot to switch them and couldn't figure out why it wasn't working! Thank you!!

exact reason I am on this!

good point! thanks!

How is this not the top comment? It's so useful!

Thanks man! Got your email too. Hope your stuff arrives soon! Let me know how it goes with the setup!

Ha! Thanks man. :)

hahaha

Excellent! Glad my parents didn't think of that ;)

Awesome man! Glad to hear it worked! Thanks!

Ha! You're welcome!

Great! Get some details about your outside beams. It's possible there is a way to get them to interact with Home Assistant.

Revelation he uses google and Alexa for the announcements and a push notification for an iPhone.

Hey DrZzs, I managed to get the RF connected a week ago, however I can't for the life of me, get the Automation to work!

excellent!

Thanks! Hope they're helpful to you!

You are very welcome!

@@DrZzs do you know a good mqtt server where i can put tasmota message on it ? Thanks. Marc.

DrZzs what mqtt broker do you have ? thanks. Marc.

you generally put tx to rx on both ends, not tx-tx or rx-rx (They stand for transmit and receive. One tx has to go to the other rx)

That's a good questions. I don't know the answer. I'd have to get an RF temp and play around with it. Do you see anything happen in the Console when the temp sensor is active? That's where I'd start looking. I wonder how an RF temp sensor sends the actual numbers for the temp?

Excellent! My Tasmotized RF Bridge has been one of the most stable devices in my smart home. good luck with it!

@@DrZzs I look forward to a high wife approval rating.

You're probably right. I'll have to look at it again. It isn't as necessary to make the fake "off" code anymore since they added an "off_delay" option to binary_sensors in HA. So now when you set up the sensor entry in HA you can set off_delay: 5s or whatever time you want for it to reset to off.

Sounds like a great setup. So no firmware change on the Xiaomi gateway?

nope, all the xiaomi sensors once logged onto the gateway appear in HA, have doors and smoke detectors which if they go off set off the house alarm. Sweet!

@@markszymura What about RF Generic controllers/Buttons? Do you know if Xiaomi Gateway "listen" this controllers? Thanks.

Really?? I better check with mine. Thanks for the tip!

nice! I have a bunch of 434mhz fans i want to try to use this on.... what range can the rf bridge transmit? will i need one in each room?

Thanks! Sounds like you're off to a great start. Generally, I would say yes, Tasmota has been better for me than OpenMQTTgateway. I know OMG is good and a lot of people use it and are happy. I'm just more comfortable with Tasmota so that's my preference. I don't know what specifically to do about the OMG access point showing up all the time. Makes me wonder if it does that by default sometimes.

👍

hehehehe Just don't tell her where I live :) We must never let our wives meet either. That could be trouble for our Smart Home future.

Thanks for this

yes. You can transmit codes from the bridge. Check out the video on the new TX switch. I show how to record a remote code that you can transmit with an MQTT command. (hopefully I put all that info in there...)

oooh, good question. I haven't tried that. Guess I better find some spent batteries, put them in the sensors and see what happens.

that's a good point. You're right, it should be. But I don't experience that delay. I'm not sure why not. I'll have to do some thinking, or watch the logs and see what's happening.

@@DrZzs👍 thanks

This is the first year Thanksgiving Point is doing one. It’s a natural fit. Should be a great place to have it.

hacking sonoff rf bridge: tinkerman.cat/hacking-sonoff-rf-bridge-433/ and custom firmware: github.com/xoseperez/espurna/wiki/Hardware-Itead-Sonoff-RF-Bridge---Direct-Hack on tasmota wiki you'll find info about the sonoff rf bridge v2, too, the one you have (in which the 2 gpio are wrongly marked....)

you can add a IR transmitter, too: 1technophile.blogspot.com/2018/02/adding-infrared-emitter-to-sonoff-rf.html

other info: github.com/xoseperez/espurna/wiki/Hardware-Itead-Sonoff-RF-Bridge

Thanks man. I'm getting another RF bridge so maybe I will finally try ESPurna.

DrZzs thank you for your videos, very well done and informative, and you're funny, which is a bonus ;-)

Thanks it's good to have options

the sonoff motion sensors are just rf devices, no wifi so no firmwares available, but you can add those sensors to sonoff basics or sonoff th, for example... even to s20 models...

So they can't be flashed with tasmota?

Jeremy Orchuk tasmota is a firmware for esp8266 devices, so no...

Thanks for the information, guess it would be better to do a plug in device for those anyway.

Jeremy Orchuk sonoff th is what you're looking, for 0 DIY hacking... www.itead.cc/sonoff-th.html Of course if you need to pilot some electric load based on those info... Otherwise go for a small wemos d1+temperature sensor shield...

I think there are some sensors that report a code for low battery. I don't expect you can get an actually battery level from these sensors since they are RF and would need a unique code for each %. The only way I can think of to see what the low battery code is (if your sensors send one), would be to put a dying battery into the sensor and watch the tasmota console for a new code. I would guess that if the sensors send a low battery code it would say so in the marketing information. If it doesn't say something about that, then it probably doesn't send one. I haven't watched Rob's latest video yet, so I can't say much else about comparing those sensors to these RF sensors. They aren't much the same though. RF is likely always going to use much less power than any Wifi (mqtt capable) sensor. If they have found a way to bring the power usage down to comparable levels with RF sensors that would be revolutionary! Hope that helps!

@@DrZzs thanks for the info. Totally agree.

Thanks! Let me know if you get stuck this weekend :) I would bet there is a way to get the Bridge to learn your codes. First test would be to get the bridge flashed then go to the console then push the buttons on your remote. Hopefully an mqtt message will pop up and you'll have what you need. If that doesn't work there is another way to get the bridge to learn codes. You can put the bridge in learn mode for one of the 16 keys then press the button on you fob. If that doesn't work either then we ask Sam Day, cuz he's a level 40 RF Bridge Wizard. If Sam doesn't know how to do it, then it can't be done. Give it a try and let us know how it goes. Good luck!

It works really good. But I´m getting this errors " Error parsing value: 'value_json' is undefined ".

It seems that the problem was with the reset automation. I had to chenge it to => payload: '{"RfReceived":{"Data":"45F765off"}}

The door sensors are still going strong. So over a year! Haven't checked the Flood sensor in a while. I should probably do that.

Thanks! I haven't heard of one, but I would be surprised if something doesn't exist that can do it. I'll ask around and see if anyone else knows.

Good question. You are probably correct. I honestly don’t know for sure.

DrZzs for that you need to decode the protocol, too, so the right device is the rflink... tech.scargill.net/rflink-and-node-red/
