Hello!

My name is Arnold. I like reverse engineering and improving my home environment - such as by measuring CO2, ventilation, and monitoring and controlling my Daikin heat pump over the main controller interface via the P1/P2 interface.

By using my software and hardware, by providing feedback and contributing to it, and by sponsoring me you stimulate me to further develop these projects!

Many thanks for your support!
