I had quite a hard time figuring out wether my heatpump would be compatible with heishamon. But once I figured out that HeishaMon was supposed to replace the CZ-TAW1 Module, I was able to figure out that I needed the CN-CNT connector. But this is where the issues stopped. Four days after my order it arrived well packaged on my doorstep. Physical installation took 10 minutes and the software setup was a breeze. I was pleased to find a template for Home Assistant integration which had me up and running in no time. This is what open source hard/software should be!
Device connected as plug-in replacement for CZ-TAW1. Came straight up with web interface for commissioning, connected to local wireless and reported parameters on its web page. Hadn't used MQTT before, so took a while to work out how to pass data to Home Assistant, but now working solidly. Just what I needed.

Great product. Extremely simple to setup and works perfectly
I order the PCB to control my heat pump. The setup process is extremely simple even if you have no electronics experience. It took me less than 5 minutes to get it to work and I can now control my heat pump via mqtt, which is fast and flexible unlike the default cloud service provided by the heat pump.
Hallo, rund rum ein gelungenes Produkt. Bei Problemen mit dem Verbindungskabel wurde mir sofort unbürokratisch geholfen. Das Ersatzkabel kam innerhalb 3 Tagen bei mir an. Vielen Dank für alles, Gruß Theo
I bought the manufacturer's WiFi adapter CZ-TAW1 thinking that I can get a lot of information from the system and can remote control it fluently. Unfortunately that was not the case. I have a HomeAssistant based system for monitoring my home and use Grafana together with MQTT as well. HeishaMon does everything that I want. This PCB was a super easy way for me to start using HeishaMon: Just unplug the CZ-TAW1 and plug in the same cable to this PCB. Simple configuration and all was working. Thanks a lot!
