In addition to the main unit it has several remote sensor nodes to measure temperature and relative humidity at a number of locations around the house. The version I have installed is based on a Raspberry Pi computer which is located close to the main electricity meter. The RPi uses Wi-Fi to communicate with the remote nodes and has a web-based interface so the data can be viewed anywhere.<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-1 is-cropped
