1. An electrical appliance comprising:
a housing;
internal electrical components within the housing configured to provide a function of the electrical appliance;
a thermal sensor arranged to detect a surface temperature of the internal electrical components;
a processor in communication with the thermal sensor, the processor configured to determine the presence of an electrical hazard when a detected surface temperature of the internal electrical components displays a particular behaviour;
a wireless communication link configured to allow communication with one or more remote devices, wherein the electrical appliance is configured to send a signal to a remote device using the wireless communications link when the processor determines the presence of an electrical hazard; and
a memory holding data relating to surface temperature behaviour associated with a particular hazard,
wherein the processor is configured to receive surface temperature data from the thermal sensor and compare this against the data stored in the memory to determine the presence of a hazard.
