This small python tool can read data from Jeelink RF sticks , decode and forward it to Mosquitto MQTT. The Jeelink must run the FHEM LaCross Sketch.

I have created this tool when I switched from FHEM to Homeassistant and wouldn't loose my cheap LaCross/Technoline temperature sensors.

Features:

• read LaCross sensors from jeelink
• publish sensor values to MQTT
• support temperatur, humidity and an "online" status of each sensor
• support "online" status of jeelink device

TODO:

• remove pyserial-asyncio dependency and use native async
• Use fnotify to reload config on change
• extend config file with MQTT and SERIAL settings
• replace sensor, which is not received by x time with unknonw received (battery change)
