Thermostat frequently disconnects from Wi‑Fi and shows offline in the app, then reconnects later.

Safety: No mains work required.

• Improve signal strength: Move the router closer to the thermostat or install a Wi‑Fi extender.
• Change Wi‑Fi channel: Log into your router and select a less congested 2.4 GHz channel (1, 6, or 11).
• Disable aggressive power saving: Turn off router features that disconnect idle devices too quickly.
• Check antenna orientation: If the thermostat has an external antenna, adjust its position for better reception.
