Hi all,
my neighbour has a solar thermal system using a FP10 pump control by Hanazeder. Based on prior work here I wrote a Python-based server that reads the pump control via RS232 (optionally via a USB-to-RS232 adapter or even a Ethernet-to-RS232 converter) and publishes the energy and sensor readings and pump state to MQTT. It also supports MQTT autodiscovery in Home Assistant.
You can find the project at https://github.com/unverbraucht/hanazeder_server - feedback welcome. I’ve attached some screenshots.
