Determining an extreme temperature location from a plurality of locations

A method of determining a hottest location from a plurality of locations, the method comprising:

• receiving, at a local device from a remote device located at a remote location from the plurality of locations and connected to the local device in a daisy chain, a remote location signal indicative of the remote location;
• receiving, at the local device, a remote temperature signal indicative of a remote temperature corresponding to the remote location;
• obtaining at the local device a local temperature signal indicative of a local temperature;
• comparing at the local device the remote temperature signal to the local temperature signal;
• and
• if the remote temperature is higher than the local temperature, the local device transmitting an output signal indicative of the remote temperature and an output signal indicative of the remote location;
• or
• if the local temperature is higher than the remote temperature, the local device transmitting an output signal indicative of the local temperature and an output signal indicative of the location of the local device.
