When I add integration, the smart things windows pops up. All it says is “Home Assistant is not configured correctly to receive updates from SmartThings. The webhook URL is invalid:”
The only option I have is close. The instructions is saying use Nabu Casa. I don’t want to pay a monthly fee when it can be done for free. All the videos I see it is suppose to have a “summit” button instead of the close button. I have spent many days trying to figure this out. Hopefully someone can point me in the right direction.
The Smartthings integration requires your homeassistant instance to be accessible by secure https . If you’re not using nabu casa you need to set that up yourself. You can use a reverse proxy to do this like the nginx addon.
