Hello Frank. (and Martin)
In the old situation with the SMO20 and the F2120 there was the NIBE-Uplink communication and app. To communicate with Home Assistant i used the GitHub - elupus/hass_nibe: Home Assistant Nibe Uplink Integration construction; this builds a new Integration in H.A. named: “Nibe Uplink Heat Pumps”. This worked fine, even without using a NibeGW Gateway.
Now I updated my SMO20 to the latest software: SMO20 to MODBUS and myUplink apps. myuplink apps delivers much more logging data of the Heat pump; very nice.
However: The Nibe-Uplink platform is still working, but is not connected anymore to the SMO20 due to the update.
My problem is the integration towards Home assistant. I cannot find the correct settings to connect H.A. to the SMO20 with MODBUS. I tried all kind of settings, but did not realize the H.A. connection.
So i had it working with Nieb-Uplink software, but cannot connect to the new myUplink platform…
