Thermostat frequently disconnects from Wi‑Fi and appears offline in the Mysa app.

Safety first: No high-voltage work is required.

Steps to improve connectivity:

• Check signal strength: Stand near the thermostat with a phone and check Wi‑Fi signal. If weak, move the router closer or add a 2.4 GHz extender.
• Use 2.4 GHz only: Ensure the thermostat is connected to a 2.4 GHz SSID and that band steering is not forcing it to 5 GHz.
• Change Wi‑Fi channel: In the router settings, select a less congested 2.4 GHz channel (1, 6, or 11).
• Re-add Wi‑Fi: In the thermostat menu, forget the current network and re-add it.

If dropouts continue despite strong signal and proper router settings, the Wi‑Fi module on the thermostat may be failing. Replace the thermostat.
