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"
It can be down but it should show a page telling that to avoid us retry again and again
I am in France. Where are you from Graeme ? the server may not be the same ?
