You cannot cut an electricity bill you cannot see. The devices in this guide fix that: smart plugs and meter sockets that show exactly what each appliance draws, in real time, in shillings. Once you know the fridge takes a third of the bill or the heater eats more than the rest of the house combined, the savings become obvious. Here is the range we sell in Kenya.
The smart plug with monitoring: Tuya 16A
The Tuya WiFi smart plug is where most people start. It switches whatever is plugged into it from the app and shows live power readings, voltage, current, wattage and frequency. Rated 16A and 3200W, it handles heaters, irons and water heaters, and it works with Alexa and Google. It is the cheapest way to discover what a single appliance costs per day.
The meter socket: Manhua TG44ME
The Manhua TG44ME is the dedicated energy monitor, the modern replacement for the Kill A Watt that older guides talk about. It plugs between the wall and the appliance and measures voltage, current, wattage and running cost on its LCD display, rated 16A and 3600W. No WiFi needed if you just want to read it, which makes it the tool for a quick audit of every appliance in the house.
The premium plug: Atorch S1
The Atorch S1 does what the Tuya plug does with more polish: 16A up to 3680W, surge protection, live monitoring and remote switching from the Tuya app. It is the pick for anyone who wants the monitoring plug as a permanent installation on one appliance, like a fridge or a server.
DIN rail meters: the whole-house view
For the distribution board, two DIN rail meters cover different jobs:
- Atorch GR2PWS: a 100A meter with a built-in relay. Set a unit allowance in the app and it cuts the circuit automatically when the allowance is used. This is the model landlords use for rental units, prepaid style, without wiring a token system.
- Atorch AT4PW: a 100A meter that also lets you switch the connected load remotely, with live readings on the LCD and the app.
Both are installed by an electrician alongside the breakers, and both talk to the Tuya app like everything else in this guide.
What the numbers mean, in practice
A meter socket changes behaviour fast. The common discoveries in Kenyan homes:
- The fridge runs 24/7 and often draws more than expected, especially if the door seal is tired.
- Standby power is real. TVs, decoders, microwaves and phone chargers left plugged in draw a surprising total over a month.
- Heaters and irons dominate while they are on. A few hours a day can outweigh everything else in the house.
- The water heater is the classic hidden bill, heating and reheating all day.
The quick picks
- First device: the Tuya smart plug with monitoring.
- Audit everything quickly: the Manhua TG44ME meter socket.
- Permanent monitoring of one appliance: the Atorch S1.
- Rental units and whole circuits: the Atorch GR2PWS with auto cut-off.
For the wider picture of cutting the bill, the energy monitoring guide and the KPLC to solar guide are the deep reads, and the starter guide puts these devices in a full smart home setup.
Frequently Asked Questions
How do I find out what an appliance costs to run?
Plug it into a meter socket for a day or a week. The meter shows wattage in real time, and you multiply the units used by your KPLC rate per unit. The TG44ME does the multiplication for you.
Can a smart plug handle a fridge or heater?
Yes, if it is rated for the load. The Tuya plug handles 16A and 3200W, which covers fridges, heaters and irons. Always check the appliance wattage against the plug rating.
What is the DIN rail meter for landlords?
The Atorch GR2PWS sets a unit allowance per rental unit and cuts the circuit automatically when it is used up. It is a prepaid-style control without installing a token system.
Do these devices work with Alexa?
The WiFi models do. The Tuya plug, Atorch S1, GR2PWS and AT4PW all work with Alexa and Google Assistant through the Tuya platform. The TG44ME meter socket is a standalone display model without WiFi.
