TP-Link Tapo P110 Mini Smart Wi-Fi Plug with Energy Monitoring
The default cheap smart plug for Alexa and Google homes, and the one to pick if you want a rough answer to what an appliance costs to run. Treat the energy figures as indicative, not metering. If you are on Apple Home, or you want Matter, buy the P110M instead.
Our editorial rating, not aggregated user reviews
Reviewers are close to unanimous on the basics. It is genuinely small, so it does not steal the second socket on a double outlet, which most rivals do. It needs no hub, schedules keep running when the internet drops, and it costs about a third of what a name-brand plug used to. Mighty Gadget called it the best smart plug on the market and scored it 90%. So why not an eight? Two flaws that each rule it out for a whole group of buyers. The first is the headline feature itself: the energy figure is a one-hour average rather than a live reading, TP-Link has said so in its own support threads, and owners comparing it against a meter report it under-reading variable loads and drifting badly below about 5 W. It is fine for spotting what a tumble dryer costs and not trustworthy for solar or for anything you would put in a spreadsheet. The second is Matter: the plain P110 does not speak it, so Apple Home households cannot use it at all, and the near-identically priced P110M can. Set against that, recurring owner reports of plugs dropping off Wi-Fi and failing to rejoin after a router reboot, though TP-Link claims a 2025 firmware fix. Excellent value, real limits.
Pros
- No hub. It joins your Wi-Fi directly and is set up from the app in a couple of minutes
- Small enough that it does not block the neighbouring socket on a double outlet, which reviewers repeatedly call out as its edge over bulkier rivals
- Schedules and timers keep running on the plug itself when the internet goes down
- Energy history is kept for you, with daily figures over the past month and monthly figures over the past year
- Very cheap for what it does, and reviewers rate it well ahead of pricier plugs on value
- Works with Alexa and Google Assistant
Cons
- Energy readings are an hourly average, not real-time power, and accuracy falls away under roughly 5 W. Owners comparing it with a meter have found it under-reporting variable loads such as a washing machine cycle. Good enough to rank your appliances, not good enough for solar monitoring
- Not Matter. The plain P110 has no Matter certification and no Apple Home support. The P110M is the Matter version, and it is easy to buy the wrong one
- 2.4 GHz Wi-Fi only, and there is a long tail of owner reports of plugs dropping offline and not rejoining after a router restart. TP-Link says firmware from 2025 addresses this
- This is the single-plug listing. The P110 also sells as a 2-pack and a 4-pack under nearly the same name, so check the quantity before you order
- Mains plugs are physically regional. A UK 3-pin is not a US 2-pin is not a Schuko, and mains voltage differs (roughly 230 V across Europe, 120 V in North America). Buy the version sold in your own country's store and never an import listing
- No IFTTT support, and Tapo and Kasa devices still sit in separate apps
- Requires a TP-Link account and the Tapo app
