Thermostat displays error 113 and cannot reach the Ariston cloud; app shows device offline even though Wi‑Fi is connected.

Safety: No mains work required.

• Check internet: Confirm other devices (phone, laptop) can access the internet on the same network.
• Restart router: Power cycle your router and modem, then wait 5–10 minutes.
• Check firewall settings: Ensure the router is not blocking outbound connections or using overly strict parental controls that might affect IoT devices.
• Test with hotspot: Temporarily connect the thermostat to a mobile phone hotspot. If it connects to the cloud, the issue is with your home network configuration.
• Wait for service restoration: If Ariston’s status page or support confirms a cloud outage, wait until service is restored.
