WallSwitch is a power relay to control 110/230V power supply remotely. The relay power supply is not galvanically isolated with terminal blocks; therefore, WallSwitch switches only the power received at the power supply terminal blocks. The device has an energy consumption meter and features three types of protection: voltage, current, and temperature. WallSwitch controls the power supply of electrical appliances connected to the circuit with a load of up to 3kW using Ajax apps, automation scenarios, the function button on the relay, and by pressing Button. WallSwitch is connected to the Ajax system via the secure Jeweller radio protocol. The communication range is up to 1000m in an open space. The device works only with Ajax radio signal range extenders and hubs.
