Thermostat does not respond to Bosch app commands when away from home, but works locally.

Safety: No electrical work is needed.

• Check local control: Confirm that the app works when your phone is on the same Wi‑Fi network as the thermostat.
• Verify cloud status: Ensure the thermostat shows as online in the app and that no cloud error codes (E01/E20) are present.
• Router/firewall: If using advanced firewall settings, allow outbound HTTPS traffic and disable any rules that block IoT devices from reaching the internet.
• Account linking: In the Bosch app, confirm that the thermostat is registered to your account and not to a previous owner. Remove and re‑add if necessary.
• Test from mobile data: Turn off Wi‑Fi on your phone and try controlling the thermostat over cellular to confirm remote access.
