Hello,
As of 12/30/24 I was able to get this node working with my T9 thermostat. Helpful hints:
Trying to piece together documentation fixes/help from others into one place (these fixed my problems).
Developer, greatly appreciate your updating your documentation in all locations. Or at least make this post sticky. Thanks.
Documentation link to API website is no longer valid. Ie. https://developer.honeywell.com is a dead link. It is now: https://developer.honeywellhome.com
If you have an existing account already set up, and it has been a year or more since you set it up, you may be using the OLD Callback Url. If you are trying to replace a Honeywell Tstat, you may need to change/update the "call back url".
Or, you get the following error when logging into udi-honeywellhome-auth.azurewebsites.net
"code": 400, "message": "The redirect URL provided does not match the redirect URL registered for the app."
Then do the following:
Open https://developer.honeywellhome.com
Login as normal.
Goto "My Apps"
Select your app, in my case it was called ISY Nodeserver
Hit the pencil edit button.
Change the Callback Url from the old one to the new one:
https://udi-honeywellhome-auth.azurewebsites.net/auth
Once that is corrected you can proceed to add the new Tstat.
