Thermostat shows Wi‑Fi connected but the Ferroli app reports the device as offline.

Safety first: Network configuration only.

• Ensure same network:
  • Confirm that your phone and the thermostat are on the same SSID (not guest network).
• Restart router and thermostat:
  • Power cycle both to clear IP conflicts.
• Reserve IP address:
  • In the router's DHCP settings, reserve a fixed IP for the thermostat's MAC address.
• Check router isolation settings:
  • Disable client isolation or AP isolation that prevents devices from seeing each other.
