DEWENWILS 40A Wi-Fi Pool Pump Timer HOWT01A1: features, specs and uses

The DEWENWILS HOWT01A1 is a heavy-duty Wi-Fi timer that switches high-power equipment on and off on a schedule. It is built for pool pumps, and DEWENWILS also lists water heaters, pool filters, spas, irrigation systems and landscape lighting. It can be controlled from a phone, so you can run the equipment without going outside.

Timer modes

The timer offers programmable, random and countdown modes, with up to 12 ON/OFF settings. The programmable mode runs the schedule you set, such as running a pool pump for certain hours each day. Random mode varies switching times, and countdown mode turns a device off after a set period. DEWENWILS says scheduling helps avoid running equipment all night if you forget to switch it off, which can save energy.

Load capacity

The specs are 40 amps at 120-277 VAC, with a 2HP load capacity. That covers many residential pool pumps, but the actual current draw and voltage of your pump matters. Check the nameplate on your equipment against the timer's limits, and have a qualified electrician do the wiring if you are not experienced.

Wi-Fi, app and voice control

The timer connects to your router with no hub. It works with the ECO Plugs app, Alexa and Google Assistant, so you can use a phone from anywhere or give voice commands. It supports 2.4 GHz Wi-Fi only, which is worth checking against your router and the signal strength where the timer is installed, since a pool area can be far from the house.

Wiring

The package comes with two updated jumper wires intended to make wiring easier. A hanging mount point at the top lets you hang it on a wall. Wiring a high-power pool pump involves mains voltage, so follow the manual, switch off power at the breaker first, and follow local electrical codes.

Built for outdoors

DEWENWILS describes a metal sealed cover and a waterproof pad, and an operating temperature range of -40°F to 140°F (-40°C to 60°C). The unit measures about 5.8 x 2.8 x 8.8 inches and weighs 1.2 lb. It is UL listed, which DEWENWILS cites as quality assurance. Even so, choose a mounting spot that suits the manual's guidance for outdoor use.

Who it suits

It suits pool and spa owners who want to automate a pump or heater, and gardeners who want to schedule irrigation or landscape lighting. It is less relevant for small plug-in loads, where a simple outlet timer would do.

What to check before you buy

• Electrical match: compare your equipment's voltage, amps and horsepower with 40A, 120-277 VAC and 2HP.
• Wiring: decide whether a qualified electrician should install it.
• Wi-Fi: the unit needs 2.4 GHz coverage at its location.
• Apps and assistants: confirm the ECO Plugs app, Alexa or Google Assistant works with your phone and setup.
• Mounting: plan for wall mounting using the hanging point.
• Heater use: check the manual on connecting water heaters.
