 - 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
+- Storing temperature, humidity and battery state as json in a text file
+- Can run on Raspberry Pi (3, 4, zero w) or any other Linux driven hardware which has BLE and WiFi support
 
 **TODOs:**
-- [WIP] Can run on Raspberry Pi (3, 4, zero w) or any other Linux driven hardware which has BLE and WiFi support
+- [WIP] MQTT publishing with discovery for homeassistant
-- [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
