This is the switch for a water heater, and the reason it exists is that ordinary smart wall switches are not rated for that load. A villa water heater circuit is protected at 20A behind a dedicated isolator, and fitting a standard 10A lighting switch there is a genuine hazard rather than a technicality: the relay contacts and the terminals are not built for the current, and the failure mode is heat inside a closed back box. This model is rated for the job. Once fitted it gives the heater a schedule, which is where the money is in a Dubai villa: the heater runs for the hour before the household wakes and the hour before evening showers rather than holding a tank at temperature around the clock. It runs on Zigbee through an Aqara hub, so the schedule keeps running when the internet drops, and it keeps a physical control at the wall for anyone who wants to override it. It needs a neutral at the isolator position and it must be fitted by a qualified electrician onto the existing dedicated circuit. Never move a heater onto a lighting switch to make it smart.

Dubai villas and most apartments have electric water heaters on dedicated 20A circuits with their own isolator, usually above the bathroom door or in a service cupboard. That isolator position is where this switch goes, and only a qualified electrician should do it. The saving is real here: a heater left on continuously in a villa is one of the larger single loads on a DEWA bill, and a two-window daily schedule covers normal household use. Do not solve this with a smart plug or a lighting switch. Neither is rated for the current, and the consequence of undersizing on a heater circuit is heat inside a sealed back box.
