I have multiple smart switch devices at home, and I’ve been able to add them overtime, however recently I bought several more, and I’m not able to add them following the same process, or other that I found online due to the firmware and app version updates. I though it was something with the new one, so I tried with one that si had before, but was also unable. As part of the process and I’m able to put WiFi information, it detects the device, and indicates in a status “pairing ...” but never finishes this step. Tried different phones and WiFi with no success. Other devices already enrolled are working fine.
