Rank #6 in Best Smart Plug 2026: 10 Ranked, and Why 13 Amps Means Three Different Wattages
EIGHTREE Alexa Smart Plug with Energy Monitor, BS1363, 4-Pack
Price and rating as shown on Amazon when we collected them. Both change.
The EIGHTREE ET32 is an energy-monitoring smart plug sold here as a four-pack, and it takes sixth place in our smart plug ranking. At GBP 27.99 for four it comes to GBP 7.00 a socket, among the cheapest four-packs on this page, at or below the Tapo P110 at GBP 7.99. It is not cheap for the usual reason: it does the same energy monitoring, cost estimation, timers and scheduling as the plugs above it, runs on the widely used Smart Life app, and carries 1,568 ratings at 4.6 stars.
It is the second EIGHTREE in this ranking, and it sits at the opposite end of the detail scale from its sibling. The ET35 at number four publishes 13 amps, 2,990 watts and 230 volts, the only listing here whose arithmetic runs on Britain's real voltage. This one publishes no voltage, no wattage and no current at all, so there is nothing to multiply. What its specification table does publish is worth reading both ways. It is the only listing on this page to name the British standard it is built to, BS 1363 and UKCA, which from an unfamiliar brand is worth more than a familiar logo that names nothing. And in the next row it states the plug has four wires, where a British plug has three, alongside a plug type given as "ELECTRICAL" and a connector type of "Quick Connect", neither of which describes anything.
How those 1,568 ratings break down
An average hides its own shape. This is the spread behind the 4.6 stars.

Quoted from customer reviews on Amazon
Verified purchaseEasy to set up and works perfectly
“Setup was super quick — it connected smoothly to my Wi-Fi and synced with Amazon Alexa without any hassle.”
Verified purchaseGood quality, very useful - much more useful than expected
“It is unbelievably useful to have the energy monitoring on a per plug basis which these offer when using the Smart Life app to isolate which devices are using the most power and just how much they are costing, on an ongoing basis.”

Questions people ask
How much is the EIGHTREE ET32 per socket?
At GBP 27.99 for four it is GBP 7.00 a plug, among the lowest on this page, at or below the Tapo P110 at GBP 7.99 and under the EIGHTREE ET35 at GBP 8.75, and it still includes energy monitoring. Prices here move week to week, so check the live figure before buying.
How many watts can it take?
The listing does not say. Unlike its sibling the ET35, which publishes 13 amps at 230 volts for 2,990 watts, this one gives no voltage, wattage or current at all, so there is nothing to convert. As a 13-amp British plug the ceiling is the socket, and a 3kW kettle or heater sits at it.
Does it actually meet British plug standards?
Its specification table names BS 1363, the British Standard for 13-amp plugs and sockets, and UKCA, the post-Brexit conformity marking. It is the only listing on this page to name a standard by number. That is the maker stating conformity on the listing; we report it rather than certify it.
Why does it say four wires?
A British plug has three: live, neutral and earth. The four in the table is a catalogue field filled in wrongly, the same kind of error as the "ELECTRICAL" plug type and "Quick Connect" connector type in the rows near it. The hardware is a standard three-pin type G plug.
Does it monitor energy use?
Yes. The listing sells it on real-time energy monitoring through the Smart Life app, with charts and a cost estimate if you enter your tariff. As with every plug here, it does not publish an accuracy figure for the meter, so treat the readings as a guide.
Does it need a hub?
No. It connects over 2.4GHz Wi-Fi and works with Alexa, Google Home and SmartThings without a hub. Being 2.4GHz only, it is the band its own 5GHz sibling at number four exists to avoid.
