Hi, we have had a garden room built about 80m from the house. Have best protect fitted and the garden room has hard wired wifi from the same router so I know the wifi network is great. When I try to install new nest protect it always fails as cannot connect to another device as house too far. I assumed as wifi network identical, it would work but can’t seem to make this happen.
During the add process, there comes a time when you confirm that it should start connecting, at which point you should make sure that your other Nest Devices (=supporting)
is active. With a nest protect you press the button so it does a self-test (which you can cancel if you want, it is then active enough).
