Sonoff POW Elite 20D 20A smart relay with power monitoring and WiFi (POWR320D / POWR316D)
The Sonoff POW Elite 20D WiFi 20A smart relay is the next part of my smart home project. I wanted to be able to measure higher loads and possibly disconnect it when we are not at home. Let’s see what it can do…

What’s in the box, what do you need to know?
The basic idea was to be able to monitor how much my air conditioner was using and set a good average for myself in the summer. Of course, we don’t just turn off anything with a compressor (like refrigerators), but with the consumption next to my needs, I can create an alarm if I reach X kWh for the month, or see how much a 1-1 degree change actually matters.
For this task, the Sonoff POW Elite 20D WiFi metering smart relay seemed perfect on paper, but it didn’t disappoint during the tests either.
It is a DIN rail mounted, single phase, dual line display meter and smart relay with Wifi. It has 16A and 20A versions. I chose the 20A rating, independent of the load…who knows what I’ll use it for in the future.
A bit more legible:
- DIN sin mountability – removable plastic fitting if you don’t want to use it in the breaker box
- One phase
- Relay with 16A or 20A load capacity
- Two-line display that does not have backlighting
- Display alternates between kWh and W/A and V every 5 seconds
It has a screw-in cable socket which is much more secure, and a plastic cover for this part.
It connects to the network via WIFI and Bluetooth is also available for pairing thanks to the new ESP32 chip.
The contents of the box are short as usual: a Sonoff POW Elite 20D WiFi metering smartrelay, a setup guide and that’s it… nothing more.
Features of the eWeLink application
Easy access to the relay switch on the main card and detailed information on energy consumption is immediately available.
By entering the more detailed menu, the following information is available:
- Electricity consumption (kWh) Today
- Electricity consumption (kWh) Yesterday
- Energy consumption (kWh) Month
- Current current (A)
- Current voltage (V)
- Current power (W)
Other settings that are interesting are the push notifications that you can use to receive a notification when you reach a set level or an alarm.
With the OPS (overload protection) function, three adjustable parameters, power, voltage and current threshold, if any condition is met, the device will switch off / relay will switch off the load.
Home Assistant and Tasmota
Thanks to the eWeLink add-on, all our eWeLink devices can now be integrated into our Home Assistant system and automations. This is no different with the Sonoff POW Elite 20D WiFi meter.
And if you need more, you can get everything you want with Tasmota thanks to the usual ESP32 flashing.
Installation
- Turn off the circuit breaker of the apartment/house that is connected to the circuit / or the main switch instead…
- You can install the Sonoff POW Elite 20D WiFi where you need it, then follow the wiring suggestion: from the original small circuit breaker to the new meter, phase and zero in the right place, and from there to the original device. DO NOT remove the old breaker, it is important that it stays in line!
- Once everything is in place and you’re sure the wiring is correct, you can get the power back on. If you’re not sure, get an electrician to do it, because you can get electrocuted if you’re not careful!!!
- Launch the eWelink app on your mobile
- Find the add button and click on it in the app
- Click on the bluetooth paring option and you will see our Sonoff POW Elite 20D WiFi device with the usual random name in the list
- Next you will be prompted for a WIFI connection, select your own wifi network and enter the password, then click Save in the top right corner
- 5-15sec to sort the data and you’re done
