The Aqara C-Wire Adapter makes installing the Aqara W200 Smart Thermostat possible even in homes that do not have a C-wire. Many older HVAC systems lack a common wire, which is required to provide continuous power for most smart thermostats. This adapter helps solve that problem by delivering stable power without the need to run new wiring through your walls. Designed specifically for the Aqara Thermostat Hub W200, the C-Wire Adapter ensures reliable operation and allows your thermostat to stay connected and responsive while supporting advanced smart home features. Installation is straightforward and typically takes place at the HVAC control board. By connecting the adapter to your existing wiring, it creates the equivalent of a C-wire connection so your thermostat can receive consistent power.
