ble_monitor VS ATC_MiThermometer

For those who are interested, the Passive BLE monitor Home Assistant integration supports quite a few thermometers. The Govee support is based on a component I wrote, Home-Is-Where-You-Hang-Your-Hack/sensor.goveetemp_bt_hci/. If you are looking for just the decoder, check out Thrilleratplay/GoveeWatcher.

However, I use some of their other (older?) BLE temp sensors, and for Home Assistant, you can use this driver for them: https://github.com/custom-components/ble_monitor

FWIW, if your HASS is running on a device (like a Raspberry Pi) that has Bluetooth, you might be able to get away with a custom component like https://github.com/custom-components/ble_monitor instead. Of course, if your setup is working for you already there isn't much incentive to change it.

https://github.com/custom-components/ble_monitor will work with govee

Once again, who knows better how to install it other than the guys who made it? No one , luckily for you, even being an Hacs integration (so not necessarily polished) the documentation seems very well written

Yes, there's an installable component with HACS : https://github.com/custom-components/ble_monitor It's working really well 👌

I want to do a little IOT project where I establish a MQQT-Broker on my Raspberry Pi and send it readings from my measurement devices (xiaomi Mijia-LYWSD03MMC). The plan is for these devices to connect to my ESP32, allowing me to transfer data to the broker on the Pi. I've successfully connected my ESP32 to my Wi-Fi and to my broker, but I'm experiencing significant difficulties in connecting it to my two measurement devices. I have essentially followed the instructions provided in this GitHub repository (https://github.com/atc1441/ATC_MiThermometer) as best as I could. I also checked some other repos but they didn't really help me as they were too big/complex...

If you get off WiFi and on Bluetooth: https://github.com/atc1441/ATC_MiThermometer They last a year with a single CR2032 which is hard to do with WiFi.

I then copied this Python script to the Raspberry Pi 4 and was able to read the temperature and humidity! (https://github.com/atc1441/ATC_MiThermometer/tree/master/contrib/python)

I’m using 16pcs Xiaomi Thermometer LYWSD03MMC BLE thermometer around the house with custom ROM from here https://github.com/atc1441/ATC_MiThermometer

I use the Xiaomi (pronounced Show Me) Mi Temperature and Humidity monitors (version 2) and flash the firmware with a 'open source' version (here or the older one here). I've found battery life good (8 months + with the newer software on one sensor) and bar from one corrupt display (right next to an outdoor electricity feed - well the box is handy and dry) then they have just run and run and run.

The thermometers in screenshot are Xiaomi Thermometer LYWSD03MMC with ATC custom firmware. Their bluetooth broadcast data collected by some cheap chinese ESP32 board and ESPHome addon in Home Assistant.

You can replace their firmware with one which is more open and broadcasts the values without needing to connect to the device: https://github.com/atc1441/ATC_MiThermometer
