Hi all,
Last weekend I assembled the Wifi OTGW board from nodo-shop.nl. I have it connected using the NodeMCU and I am able to receive information from the boiler (Remeha Tzerra). However the iSense thermostat give the f203 error (and the backlight does not work). when I connect only the iSense to the OTGW board and check the log in otmonitor no data is received at all from the thermostat. I measured the thermostat connector on the OTGW and it showed ~23volt.
Do you guys have any idea what is wrong?
Thanks a lot in advance!
Maarten
