Unable to connect Honeywell Lyric T6 thermostat with HA

Happy new year!

Last week I have bought a Honeywell Lyric T6 thermostat. Everything is working fine with the Resideo App but now I also want to connect it to Home Assistant.

On the Honeywell developer site (Resideo) I already have created an App with a consumer key and secret but when I add the integration in HA, I am getting the message ‘invalid client_id’.

Can someone help me to get this working?

Thanks,

Tjerk
