Refresh in Google Home

I’m struggling to get the refresh option with the test app. Is this what the refresh service is supposed to do?

I don’t know if that’s how its meant to work using the api key, but after 24 hours my 1 wemo light never came across from HA so i un-linked and then re-linked and it came across.

It’s a bit of a pain having to re-assign the devices to rooms again in the home app though

After running the service things turn up so no need to relink!
