ATC_MiThermometer_Gateway

Python gateway for the custom firmware for the Xiaomi Thermometer LYWSD03MMC.

Roadmap

Done:

  • Make in runnable in a docker container (because only cool people are using docker)
  • Make docker image smaller. I mean shiiit 1GB D: should be possible to be under 500MB (It's now around 100MB)
  • Implement a loop for fetching the data every X seconds

TODOs:

  • [WIP] Can run on Raspberry Pi (3, 4, zero w) or any other Linux driven hardware which has BLE and WiFi support
  • [WIP] Storing temperature, humidity and battery state as json in a text file
  • [TODO] Make a microPython version for using the raspberry pico w or any other microcontroller with BLE and WiFi support
  • [TODO] Collect data from multiple devices/gateways
  • [TODO] Command line tool for managing the devices
  • [TODO] Analyzing tool for making statistics
  • [TODO] HomeAssistant integration
  • [TODO] MQTT publishing
  • [TODO] Maybe... a webinterface. But I suck at web stuff, so I don't know.
  • [TODO] Implement other BLE Sensors

Current State

Getting started

First of all, you need to flash the custom firmware on your LYWSD03MMC device. A step-by-step guid is in his youtube channel, the video is linked on his GitHub repo. It's straight forward and does not require any special hardware.

Run Gateway

The libraries are needed to be installed as root, because the gateway itself needs to be executed as root, else it is not able to use the bluetooth adapter. In the future, I try to do it better. Also in the future it will be much easier to start and install.

Install bluez. It's needed for bluepy to communicate with the bluetooth adapter.

sudo apt-get install -y bluez

Install PIP Libraries

sudo pip3 install -r python/requirements.txt

Run Gateway

cd python/src
sudo python3 main.py

Shell Scripts

build_docker.sh

Arg Meaning Default
-t | --tag Set a tag for build develop
-i | --image Set a image name for build dasmoorhuhn/atc-mithermometer-gateway
-h | --help Get this help in the CLI

run_docker.sh

Arg Meaning Default
-d Run in Backgrund
-t | --tag Set a docker tag develop
-b | --build Build the image before running the container
-l | --loop Start the gateway in looping mode
-a | --api Start with the API false
-tz | --timezone Set the timezone Europe/Berlin
-to | --timeout Set the timeout for the bluetooth scan 20
-h | --help Get this dialog in CLI

Docker

Build docker container ()

sh build_docker.sh
# Or
sh build_docker.sh -i your-image-name -t your-tag

Run docker container. Killing the hosts bluetooth service is needed to access it from the docker container.

sudo sh run_docker.sh

MicroPython for MicroController

Coming when I develop it...
