Thermostat loses Wi‑Fi connection frequently and drops out of app

Safety first: No mains work required.

Steps:

• Check Wi‑Fi signal strength at the thermostat location using a smartphone; if weak, move the router closer or install a Wi‑Fi extender.
• Change the router's Wi‑Fi channel to a less congested one (1, 6, or 11 on 2.4 GHz).
• Disable aggressive power-saving or band-steering features that may disconnect IoT devices.
• Update router firmware and thermostat firmware to the latest versions.
• Re-add the thermostat to the Heatmiser app after performing a Wi‑Fi reset on the thermostat.
