The LUX Power Bridge provides 24V AC power to thermostats in homes without C-wires. Thermostats that connect to WiFi networks and home automation systems like Amazon Alexa and Apple HomeKit need a consistent 24V AC power source for optimal performance. The LUX Power Bridge allows homes with 3 and 4 wire systems to reap the benefits of smart thermostats without requiring a new wire to be installed between the furnace and the thermostat.
