I have posted information in other topics, but just to keep everyone informed, I have heard that SmartThings are changing the rules of the PAT. Newly issued PATs will expire after 24 hours and will have tighter rate limits. That obviously makes them useless for use with Homey.
The only alternative is to switch to an OAUTH2 login, but the private tokens only support 500 users. That is also useless for Homey as my current app has around 1500 users.
It’s possible to request a token that supports more users, but I have not had a response to the request. Also, I believe those come at a cost, which I think is why Athom abandoned their official app.
Old PATs should continue to work as before, so if you have already been using the app then it should continue to work.
Unfortunately, I feel this is the end of SmartThings integration with Homey, unless I get a response about a more suitable OAUTH2 token.
