The most affordable way into Sonoff energy metering is the POW Origin — a 16 A relay that reports power, current, voltage and accumulated kWh to the eWeLink app, breaks usage down by day and month, and exports a six-month hourly archive to Excel from your phone.<br><br>The module wires into the appliance line: both live and neutral land on its 1.0–4.0 mm² terminals, and the case clips onto a DIN rail in the panel or sits in a box next to the boiler. Threshold protection cuts the load when power, current or voltage leaves the limits you set, a push notification flags the daily consumption goal, and schedules plus Alexa and Google Assistant voice control run through eWeLink.

What you need on your side and what we deliver.
Three typical automations we set up after the install.
On the line of an 80-litre boiler in a Chișinău flat, the relay shows how many kWh go into hot water, and the hourly history tells whether night heating pays off.
Before central heating starts, an electric radiator runs on a schedule, and a push arrives when the daily goal is exceeded — consumption stops being a surprise.
A week of eWeLink charts shows what a fridge in a house near Chișinău really draws and helps decide whether a replacement is worth it.
Real-time consumption tracking via the eWeLink app. Daily, weekly and monthly history helps identify the most energy-hungry devices.
