Had the relay on charge all night along with the cell. Both working fine in the house. Went to town and tested it as the wife went in the Post Office. When I opened the app, I got the message (in the RW Relay App) I was not on the Internet. And the app would not start. The Relay had a solid red light on and it would likewise do nothing.
After some time, when I got on WiFi both seemed to work okay.
I was not aware I had to be on WiFi for them to work ?
And the app keeps telling me the volume is too low and I might miss messages. But the Relay was at max volume.
