I added a new switch to my eWeLink app and went to Google home to relink so that the switch was visible. The link appeared to work and the devices, including the new switch appeared in the list, however, when I attempt to turn the switch on or off from Google Home, I get a response "Sorry there was an error and I am unable to control your home device"
You can also say to Google: "Resync my devices". That should get it to see the devices again. You can use this instead of re-linking your account.
