Thermostat shows Wi‑Fi connected but mobile app cannot control or see the thermostat.

Safety first: No electrical hazards; do not open the thermostat.

• Update app: Install the latest version of the Payne thermostat app on your phone.
• Check account: Ensure you are logged into the same account that originally registered the thermostat.
• Re‑pair device: In the app, remove the thermostat and add it again using the pairing process.
• Check router settings: Disable client isolation or AP isolation on your Wi‑Fi router so your phone can see the thermostat.
• Factory reset thermostat: As a last resort, reset the thermostat and set it up again from scratch.
