Best smart-plug routes by need
| Model | Best fit | Main reason to avoid |
|---|---|---|
| TP-Link Tapo P100 | Simple Tapo app, schedule and voice-control use where energy monitoring is not required | No plug-level energy monitoring; older hardware versions and pack contents must be checked |
| TP-Link Tapo P110 | 2.4 GHz Wi-Fi control plus Tapo energy monitoring for a suitable indoor appliance | Not Matter or Apple Home; manufacturer load restrictions still apply |
| Eve Energy (Matter/Thread) | Local Matter-over-Thread control and energy data in a compatible platform/Eve setup | Needs the correct Matter controller and Thread border-router route; no retailer CTA is retained here |
| Meross MSS315 UK | Matter-over-Wi-Fi and Meross energy monitoring where the exact UK version fits | Requires a suitable 2.4 GHz/IPv6 network and Matter controller for the chosen platform |
| Kasa KP115 | Existing Kasa households maintaining a supported installed device | TP-Link marks it as phasing out and points buyers to Tapo P110; it is not a current default recommendation |
1. Tapo P100: simple control
Choose P100 when the requirement is a compact indoor plug for manual app control, schedules, timers and supported voice control, with no need for energy data. TP-Link still lists it in the current UK smart-plug range. It may be sensible for lamps and other suitable low-risk devices already managed in Tapo. Avoid paying for a multipack until one unit has been checked in the intended twin socket and on the household’s Wi-Fi.

2. Tapo P110: energy-monitoring value
The P110 adds energy monitoring to the Tapo route. TP-Link’s official UK page lists 2.4 GHz Wi-Fi, no separate hub, local control, schedules and a 13A maximum indoor output. It also says EV charging is unsupported and gives a restriction for larger motor/compressor loads. Match the exact appliance rather than using “13A” as blanket approval.
Energy data is useful for answering a defined question—such as measured standby consumption or runtime. It does not save money by itself. Compare measured kWh before and after a safe schedule, then apply the household’s actual tariff.

3. Eve Energy: Matter over Thread
Eve’s official Energy page documents the current Matter/Thread product and its energy functions. It suits buyers who deliberately want Matter-over-Thread, local operation and the platform support exposed by their Apple, Google, Alexa or SmartThings controller.
Do not assume “Matter” means no infrastructure. A Matter controller is required, and a Thread product also needs a Thread border router. Check whether the chosen platform exposes energy history or only on/off control. The previous Amazon route is omitted because its redirect evidence was not sufficiently reconciled for this release.
4. Meross MSS315: Matter over Wi-Fi
Meross lists a UK MSS315 with energy monitoring in its official product catalogue. It is a different network route from Eve: Matter uses the existing compatible Wi-Fi/IP network rather than Thread. Confirm the UK version, exact Matter-controller requirements and whether energy data appears in the Meross app, the chosen ecosystem or both.

Who should avoid a smart plug?
TP-Link’s official KP115 page labels that Kasa model as phasing out and identifies Tapo P110 as its replacement. Existing KP115 users can follow current support information, but new buyers should not choose it for an assumed long-term Kasa advantage.
Do not use one for medical or safety-critical equipment, an appliance that must remain powered, EV charging, or anything whose unattended start could be hazardous. Portable heaters, cooking appliances, compressors, pumps, refrigerators and other high-load or continuous devices require explicit approval from both manufacturers—not a generic wattage assumption.
Also avoid buying when the wall socket is loose or damaged, the plug would be enclosed behind furniture, the Wi-Fi is unreliable, or nobody will maintain the account and firmware. A permanent smart wall socket or professionally designed control may be more appropriate for a fixed load.
Ownership, privacy and offline behaviour
Compare hardware, hub/controller requirements, app account, support period, standby draw, multipack waste and replacement cost. Check what schedules continue without internet, the power-restoration state after an outage, data export, household sharing and account deletion. Use unique credentials, enable available two-step verification and install updates.
For load and overheating checks, read the smart-plug safety guide. Continue to energy-saving devices, energy monitoring, smart wall sockets, Matter and the budget guide before expanding to a whole-home plug fleet.
Related UK control routes
For heating, use the radiator-valve guide, thermostat guide and savings-method guide. A plug-in control is not an EV-charging substitute; see the EV installation guide.
The wider navigation path retains the energy-control hub, canonical smart-plug guide, wall-socket guide, light-switch guide, smart-bulb guide and lighting-system guide. These solve different installation problems and should not be treated as interchangeable products.
