Have been running some 433 plugs with my Heart for a couple of months controlling it with Google Home. But after adding a new plug and trying to sync with Home i get the error message " The account owner will need to sync Animus Heart" while my Philips Hue bridge syncs just fine. Tried removing remote access and adding it again without any luck. Is there a quick fix?
Have you updated to the latest version of your Heart?
Go to settings->update and check for updates to see if there are later releases.
