Thermostat or gateway feels unusually hot to the touch or is installed in a very warm location, causing erratic behavior.

Safety: If you smell burning or see smoke, disconnect power immediately and contact a professional.

Steps to mitigate overheating:

• Relocate thermostat: Move the thermostat away from radiators, TVs, or direct sunlight to a cooler, shaded interior wall.
• Improve ventilation: Do not enclose the gateway in a cupboard or behind other electronics. Allow air circulation around it.
• Check power supply: Ensure the correct power adapter is used and that it is not overheating.

If overheating persists in a suitable location, the device may have an internal fault and should be replaced.
