Smart thermostat for 16 A loads

The MHCOZY TH16 is a Wi-Fi 2.4 GHz smart thermostat that switches resistive or inductive loads up to 16 A and 3000 W from a single gang box. It includes a waterproof DS18B20 probe on a 1 m cable for ambient sensing from −55 °C to 125 °C.

Fits a standard junction box

The unit measures 9.4 cm × 5.7 cm × 3.3 cm and weighs 50 g, so it sits inside a typical wall cavity behind a blanking plate. It needs an 85–250 V AC supply and a 2.4 GHz Wi-Fi 2 router; the app then handles scheduling, voice scenes and real-time power data without extra hubs.

Suits single-zone heating control

Installers automating one heater, towel rail or under-floor mat will use the auto-range and timer functions daily. Buyers who need multi-zone scheduling, humidity-triggered actions or 5 GHz Wi-Fi backhaul should look at a different controller.

Questions about this item

What is the maximum current the MHCOZY TH16 can handle before it trips?

The switch is rated for 16 A and a maximum load of 3000 W at 85–250 V AC. Exceeding 16 A will cause the device to shut down for safety.

How hot does the unit get when it runs continuously at full load?

The housing is specified for an operating range of –20 °C to 70 °C. At 16 A the internal components will approach the upper end of that range, so mount it in a ventilated enclosure.

Which sensor must already be wired in for temperature control to work?

The included 1 m waterproof DS18B20 stainless-steel probe (range –55 °C to 125 °C, 3.0–5.5 V) plugs into the switch and must be installed before the thermostat can regulate anything.
