Honeywell T6 Pro Z-Wave Thermostat not working

Need to get a Honeywell T6 Pro Z-Wave Thermostat working with Homey Pro, but haven’t been successful. Installed the Homey Pro Honeywell app & when pairing it, I get an error message indicating that the device is unknown. It adds it as a device anyway, but when clicking on this device it indicates an error as an unknown device.

Does anyone have a Honeywell T6 Pro Z-Wave Thermostat working with Homey Pro?

Hello! Any success on this?

The honeywell home app isn’t working anymore. it seems the api certificate is expired and i found some news regarding a new end point api.honeywellhome.com instead of api.honeywell.com. Who can fix this?

Thanks for bringing this up @Niels_van_der_Voort .

Has anyone successfully connected their T Series thermostat? I get stuck on the credentials page. I have the Honeywell “First Alert” app and those credentials do not work. I notice the credentials page when trying to connect is called “Resideo”. I am wondering if I need to create new credentials somewhere else.
