How to Fix / Troubleshooting

Safety first: No hazardous voltages for battery devices.

Steps:

Reboot gateway: Power cycle the Ally Gateway and wait until it is fully online.
Reset thermostat: Perform a factory reset on the thermostat to clear any previous network information.
Start pairing correctly: Use the Ally app to start device discovery, then put the thermostat into pairing mode as described in the manual.
Move closer: Place the thermostat within a few meters of the gateway during pairing.
Update firmware: Ensure the Ally Gateway firmware is up to date before retrying.

Thermostat does not appear in the Ally app during initial setup, even when in pairing mode.
