ATC_MiThermometer VS Home Assistant

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

Apparently the same issue has been reported with Philips TV [1] and Fritz!Box [2] as well.

The plug would transmit power readings to my Home Assistant setup.

Home Assistant can cast dashboard/media/etc to your display and has shopping lists. https://www.home-assistant.io/

If you provided MQTT support like plenty of IoT companies do, then any open source home automation tool can integrate! Home Assistant (https://www.home-assistant.io/) have a grading system, so a local-first implementation would give you their highest score since they also really care about privacy. https://www.home-assistant.io/blog/2016/02/12/classifying-th...

It's hard not to raise a little smile at Google's automation scripts, which bare a not-entirely-passing resemblance to those of a certain other, more comprehensive home automation system...
