The AEOTEC Heavy Duty Smart Switch handles 40 amps at 220 volts. That puts it in a different category from most smart home switches, which typically top out at 15 or 20 amps. This one is built for the big stuff: electric water heaters, well pumps, EV chargers, or workshop machinery.

The switch works as a Z-Wave Plus device, so it integrates into an existing smart home hub without needing its own app. You get reliable wireless control and the ability to set schedules. The real value is the energy monitoring. It reports real-time power consumption, which lets you see exactly what that old water heater costs per month. You can then use the scheduling to turn it off during peak rate hours.

One honest limitation: this is an ON-OFF switch, not a dimmer or variable controller. It also requires a neutral wire and proper 220V wiring knowledge for installation. If you need to control a heavy appliance and want to track its energy use, this is the most straightforward solution available. It feels solid in the hand and the relay clicks with authority.
