For Homey can you find the channel it’s using on Homey Developer, under System Information. I don’t think it’s possible to check which channel the IKEA gateway is using, but I think it’s always 11.
Homey requires an internet connection to be able to update its access tokens, which are used by the app and the website (https://my.homey.app) to log in on your Homey. When those tokens expire and you don’t have an internet connection, you’ll get an error message saying that Homey is offline (although most flows will still work, you just won’t be able to control Homey).
