New Homey user and while adding all my devices, Samsung Smartthing keeps saying this error, I’ve generated countless tokens with different approvals, starting with just apps as instructed, then installed apps, devices, etc but none seem to work?

I’m also struggling with Nest devices, I go through the whole log on then it just goes back to the app with no devices shown? Chromecast seems fine.

You need a subscription for the SmartThings API (required for use with Homey). Do you have this subscription already? You can subscribe on the SmartThings developer portal

Thank you for coming back so quick!

So it’s now a paid API integration for Samsung? Even as a personal user?

Yes, with the recent changes to the API, you need an API subscription to integrate SmartThings with Homey

Hi Jason,

If you have Home Assistant installed, there’s a [local API](https://github.com/mbillow/localthings) alternative. You can then use the HA Community-App to send the data to Homey.

Thank you both, I managed to get it running on the Samsung TV community app!

I’m now struggling with the Google Nest app (official) - I grant all the access to my doorbells and cams but after it goes straight back to the app without adding any devices?

Does the Homey mobile app restart after you logged in at Google and sent back to Homey? I also have this sometimes, it means your phone’s RAM is almost 100% used and Android closes the Homey app when the browser opens. Fix is usually to close some apps or reboot your phone

Thank you, I’ve managed to get to both working finally! Restarted my phone and around 4 attempts later, it found them!

Appreciate everyone’s help!
