I love 433MHz sensors because they are cheap and work over a long distance. My most complicated device is this weather station with many sensors. We also use BLE devices like the Xiaomi body scale in our bathroom. Today I will show you how to connect such devices to your smart home without hacking. And, as usual, you will learn some tricks and why the BLE proxy of Home Assistant sometimes does not work.

This presents a perfect solution for the b-parasite capacitive soil moisture sensor (Florian is a contributor). I was planning to set up an entire raspberry pi just to pick up the BLE sensor readings for a few plants, but there is no need for that anymore. There is no need to waste the power, space and an expensive pi. Now I can hide the BLE-MQTT gateway in a wire wart. Thank you!

Thank you Andreas, great as usual. My 2 cents: 1- people around (the community) is unbelievable, having so much time and sharing with all! 2- majority of users (of anything) NEVER change passwords or even apply one - I could easily turn off heating system of all my neighbours who just bought this winter thermostats - nobody bothered to secure it! ;-)

@kyleolson8977 Год назад

The question is - does it matter that nobody changed the thermostat password? Nothing in your home is completely secure from local attacks. I can trash the flowers in your garden. I can egg your house. I can break your windows, run into your house, and grab the computer and run out if you aren't read. Your home thermostat isn't likely a valuable target, as long as we're talking about target local attacks (not internet attacks to make it part of a Botnet). The thermostat being set wrong might make you very cold, but it's going to be hard to use it to do serious damage outside of a complex TV Murder plot. Few people aren't going to have a malicious neighbor who knows enough to use 433mhz to mess with it from 200 yards away. The password on the thermostat is not nearly so important to protect against you, Mr. Homonto, unless you are a serial neighbor thermostat changer. It's about the other people in the same house who don't have permission to mess with it, and many households aren't worried about that.

just think, a burglar could inject water into the door lock, turn off the heat, and the water will freeze and break the lock. then they can turn up the heat and enter with no restriction! better change that password right away, your security depends on it! 😂 just kidding, but I lock my doors and don't leave the keys in my car... and can't believe some people still refuse to do so. I like to make it just a little challenging for the bad guys so they'll go to the unsecured targets instead.

@mindshelfpro Год назад

Awesome and timely video. I use RTL_SDR dongles on the USB ports of several OpenWRT flashed TP Link Router/APs whose primary use is Wifi range extension and secondary use as general purpose Amateur Radio listening (saving Raspberry Pis), and was going to run RTL433 on one of the APs. I also got some ESP32 boards to start ESP BT Proxy to integrate a BT Lock I received with HA. I was actually looking into using a BT dongle on an AP and see if it was possible to setup a BT Proxy with OpenWRT since I already have 4 OpenWRT APs around the house. This Lora ESP32 alternative is enticing. Again saving Raspberry Pis and keeping the RTLSDR dongles for other projects. Thanks for the introduction to this solution!

@bertdebondt9145 Год назад

I've been using 2 Sonoff RF bridges some 3 years now. They work great. Replaced internal RF chip first with Portisch firmware for RAW capturing even more RF signals. Later replaced the Portisch with even more tuned versions of the original Portisch EFM8BB1 firmware. (for ex. Halfbakery's,...). I use this for some RF PIR sensors, but also to send RF commands to my garage doors ( which I first captured using RAW sniffing with the SonOff bridge of my original garage door hand remotes). In parallel of the RAW mode (RfRaw 177), I let a custom rtl_433 Home Assistant Add-on subscribe on the RAW stream. The rtl_433 HA Addon can decode even more complex RF protocols (like weather stations,...), so I can see multiple temperature sensors in the area, the publish nicely with a treeview in the MQTT broker. So I guess it's the same RF protocol list as the OpenMQTTGateway you now decribed, but there the ESP32 chip handles it all. The only downside of the Sonoff RF bridge is signal strength/antenne & with longer distance the receiving RF packets gets split into more packets. (unusable to decode or resend) That why I am curious to test out that LilyGo Lora32 433Mhz board, the antenne looks better than the spring antenne inside of the Sonoff RF Bridge. Also the the protocol (de)modulation (FSK, GFSK, MSK, GMSK OOK, On/off keying) is handled by the Lora RF chip. I'm also interested to see if I can also sniff RAW RF codes with the Lora Board and are also able to (Re)Send RF (RAW) signals. I looked at the OpenMQTTGateway documentation and I think it can also send RF signals by publishing to the MQTT broker Topic. So I just ordered one with your affiliate link. Anyhow, again a great informal video by the Swiss Guy 🙂

@AndreasSpiess Год назад

You seem to know what you do. Maybe you have to do some coding to achieve everything you want. And also, the list of supported devices is not as long as with established projects. The receiver of the LoRa boards is quite good and you can add an external antenna (maybe you watch my antenna videos).

@akiko009 Год назад

Nice. I've run into enough instability over long periods of time (months) that I've also integrated a hang/crash/noactivity detect to my 433 receivers. That way the units will reboot if it stops processing data. It's pretty easy to implement a python sanity check, and the only special case was when one RTL-SDR started repeating received data, regardless of what was actually being received. (I think it was a driver issue.)

@AndreasSpiess Год назад

RTL_433 probably was not intended for "productive" use. We started to misuse it because it was so handy...

@SmithyScotland Год назад

Yet more stuff I didn't know I needed. I currently use an RTL dongle attached to a pi, but it seems to consume a fair amount of CPU and energy.

@ziomalZparafii Год назад

Yeah, I run Node-RED (and other bits of my home automation) on RPi1 512MB and to use RTL I had to use Linux tricks to limit CPU usage like "nice" or some similar settings. It just wanted to consume it all.

Hello Andreas, as usual this is again a great video and great content from you. The only small remark/experience from me: after watching your video I was like: hey as Andreas mentioned, let's get rid of my bulky DIY RFLink box attached to my HA Raspi 4. I have ordered the TTGo board and flashed it. Unfortunately I couldn't discover any of my devices (mainly PIR sensors and Remote controlled RF433 power sockets) I went to the OMG community page and unfortunately I discovered that the chip on the TTGo (also on the Heltec Lora board) does not allow changing from rtl433 to RF / RF2 / Pilight (Switching Active Receiver Module functionality) This is not a big deal I will buy another same board as I wanted to start playing with Lora anyway but maybe you should have mentioned it in the video (of course if you were aware). Thanks anyway, I will setup the BLE proxy now ;)

@AndreasSpiess Год назад

The chip should not be the problem. But maybe your sensors are not yet supported by the software (I thought, I mentioned that not all are supported). Maybe you go to their GitHub and ask for the support for your particular sensor.

@erich7431 Год назад

@@AndreasSpiess Yes you’re right this is not the chip itself but currently the devs have not yet added support for RF/RF2/Pilight on this chip. I got confirmation on the community page and also there’s a compatibility page in the documentation (I should have read before purchasing the board ;) ) stating the ttgo board does only support rtl433. My sensors are using RF transcoding. I will reinstall OMG on an esp32 or 8266 board with srx/stx882

Thank you for your effort. This would be the third possibility to connect 433MHz sensors. Currently I am using RFLink for 433MHz. Unfortunately the latest SW is of 2017, but it still works stable. In 433MHz I am using sensors only, because actors do not have a backchannel. Some people are using ESPHome as 433MHz Gateways. Up to now I do not use BLE sensors at all, because using Zigbee or Homeatic. But we will see, what future will bring.

@AndreasSpiess Год назад

I also used RFLink but never liked their closed source approach. But I agree, it was stable. BLE is cheap and supported by the Smartphones. So I assume it will survive. But I also use Zigbee. Usually, I adapt the communication to my "sensor of choice" for a particular purpose.

The receiving frequency has to be right. And the protocol supported by the project. I do not know if they already support 915MHz devices (because I do not have such devices). Maybe you ask on their project page?

Excellent video! Do you know if the less expensive Lilygo boards, like the TTGO T-Higrow LoRa Shield 868Mhz / 915Mhz Function Expansion Board, can be used? Obviously they need power, but there seems to be little need for the SD card slot and display. I believe the board you used is aimed at counting devices passing by.

You can use all sorts of boards if you manage the GPIOs yourself. But you need a LoRa module, of course.

@divingquokka 10 месяцев назад

I could not get a different model (even with SD card slot and a display) to work with stock OpenMQTT. I donated it to the developers so they can try to make a version for it and bought the supported one. So before you buy, check if your particular board is supported.

@dan-nutu Год назад

I was thinking the same - does this new combination (ESP32 LoRA 433MHz + RTL_433_ESP/OpenMQTT Gateway) support all the devices that the old combination (RPi + USB RTL-SDR + rtl_433) support? It would be nice to have a way to send 433 MHz modulated signals to test this, similar to rtl_433 but working the other way around (i.e. modulating rather than demodulating signals). As you say, these LoRa ESP32 modules also have the 433 MHz transmit hardware. At some point somebody will write that software. I can think of some silly pranks, too, e.g. broadcasting tropical temperatures to your neighbours' weather stations in the middle of the winter :)

@jrbenito5983 Год назад

@@dan-nutu At this time the OpenMQTTGateway has a limited support regarding RTL_433 Protocols. For instance, it only supports OOK based protocols and not FSK ones for now. I believe this is constrained by the resources on ESP32 and radio configuration, different from a SDR decoder software, the LoRa module cannot do all modulations at the same time and its reconfiguration takes time.

I do not know which sensor you use. If the sensor supports 433 or BLE and is on the list of supported devices, you can use it. If the ESP32 does the measurement, I would go with the Wi-Fi of your ESP32 for transport. Then you could use ESPhome or Tasmota, if one of them supports the sensor you use. If you just use the ADC, both should work. And both support MQTT. Then you only need one ESP.
