Wireless smart relay for mains-voltage circuits that brings any 110V or 230V load up to 3 kW under Ajax control — wall lights, ceiling fans, AC units, electric heaters, pool pumps, water heaters, garden floodlights, anything you’d want to switch remotely or schedule automatically. Where Ajax Relay handles low-voltage circuits via a dry contact, WallSwitch connects directly to mains, with built-in power consumption monitoring that streams real-time wattage and historical usage to the Ajax app — so you finally know which device is the silent power hog, and you can shut it down with one tap. Compact enough to fit inside a standard wallbox behind an existing switch, WallSwitch operates in three modes selectable in the app: bistable (toggle on/off), pulse (timed activation up to 255 seconds for momentary loads), and counter-action for sequence logic. It pairs with the Ajax Hub 2 over the encrypted Jeweller radio protocol at distances up to 1,100m line-of-sight, includes two-way communication so the hub confirms every switch action, and supports tamper detection plus overload protection that automatically disconnects if the load exceeds safe limits. Operates from -10°C to +40°C, with up to 100 WallSwitches per hub. Triggered by any device or scenario in your Ajax system: arm the alarm at night and the porch light comes on, a fire detector trips and the boiler cuts off, schedule the pool pump for off-peak hours, dim the lounge ceiling load when a movie scenario fires. Ideal for villa automation upgrades, retrofits where smart switches are needed without rewiring, and commercial spaces tracking per-device energy consumption.
