Connecting the NuHeat Signature floor heat thermostat

Hello,

I’m new to Home Assistant and am trying to setup my Nuheat Signature thermostat.

I have retrieved my device id and added the settings to my configuration.yaml but am receiving an error on startup. I did notice that Nuheat made changes to their API so I am wondering if this integration is now broken.

Do I need to sign-up for access to their API to make this integration work? I’m not a programmer but am tech savy. I have been able to get almost everything else working so far.

Any help would be appreciated.

Thanks!
