Thermostat frequently disconnects from Wi‑Fi and loses connection to the mobile app.

Safety: Network changes are low risk; avoid opening the thermostat while powered.

• Step 1 – Check signal strength:
  • In the thermostat or app, view the Wi‑Fi signal level.
  • If low, move the router closer or add a Wi‑Fi extender.
• Step 2 – Change Wi‑Fi channel:
  • Log into the router and select a less congested 2.4 GHz channel (1, 6, or 11).
• Step 3 – Disable router power saving:
  • Turn off aggressive power-saving or client isolation features that may drop idle devices.
• Step 4 – Ensure stable power to the thermostat:
  • Frequent reboots due to power dips can appear as Wi‑Fi drops.
  • Check power supply stability.
• Step 5 – If issues persist:
  • The thermostat Wi‑Fi module may be marginal; consider replacing the Protherm smart thermostat.
