Thermostat frequently disconnects from Wi‑Fi; app shows device offline intermittently.

Safety: No mains work required unless relocating the thermostat.

Steps:

• Check signal strength: Stand near the thermostat with a smartphone and check Wi‑Fi signal. If weak, move the router closer or add a 2.4 GHz access point.
• Change Wi‑Fi channel: Log into your router and select a less congested 2.4 GHz channel (1, 6, or 11). Avoid auto channel if it changes frequently.
• Avoid metal enclosures: If the thermostat is mounted in a metal box, replace it with a plastic back box or use a surface-mount kit.
• Static IP or DHCP reservation: Configure a DHCP reservation for the thermostat to avoid IP conflicts.

Outcome: If dropouts persist despite strong signal and stable network, the Wi‑Fi module may be degrading; replacement may be required.
