Verdict: buy it for a specific measurement or control job
Review method: we compared manufacturer documentation with the selected Amazon.com listing on September 27, 2026. This is a specification-based editorial review; we have not bought or physically tested the product. Calculations below are illustrative, not measured performance. We do not reproduce customer ratings or assign a test score.
This review covers the P110M US two-pack, ASIN B0DKGBP38V. It combines a switching function with energy information, so it can be useful for a desk lamp or other equipment whose instructions permit external switching. A sensible starting question is: “Will this help me identify use I can actually avoid?”
Our editorial preference would be to use one device for a clear trial before expanding across an apartment. If an ordinary switch already solves the problem, automation may add convenience rather than financial savings. If you only need a short measurement session, borrowing a suitable meter can be the better purchase decision.
Specifications to check on the exact version
| Decision point | Practical meaning |
|---|---|
| Network | 2.4 GHz Wi-Fi; Bluetooth is listed for setup. Do not buy expecting a 5 GHz-only network to work. |
| Electrical rating | The US product page lists 100–125 V, 50/60 Hz. Match the delivered label; do not use this review as approval for 230 V. |
| Load type | Listed maximum: 15 A / 1,800 W for general or resistive use, with a separate 1/6 HP motor limit. The watt figure is not universal appliance compatibility. |
| Functions | Energy tracking, cost estimates from rate inputs, schedules and remote switching are advertised. |
| Selected package | Two plugs. Check the listing selection because different packs and regional products share similar names. |
The manufacturer’s US page is the rating source here. We have not independently checked measurement accuracy, tiny-load resolution, radio range or reliability. For a heater, compressor or equipment with a high starting current, obtain explicit compatibility from both manufacturers rather than relying on the headline current alone.
Matter support: verify the feature, not just the logo
TP-Link has announced energy-reporting support through Matter 1.3 firmware, initially for the P110M. That announcement does not establish that every regional unit, firmware version and controller combination will show the same energy history today. A platform supporting on/off control does not by itself prove that its interface displays energy data.
Before purchasing for an existing smart home, write down the plug hardware version, the controller or hub you use and the particular function you need: present watts, cumulative kWh, history or automation triggers. Check current support for that combination. The firmware announcement also calls for updating the product and hub.
For apartment Wi-Fi, check whether you can connect personal smart devices and whether the network isolates clients. Keep access limited to people who need control. A remote-control feature is useful only if you are comfortable maintaining another connected device and its app.
A standby-savings example that includes the plug itself
Suppose a compatible device has an avoidable 5 W standby load for 16 hours a day. At $0.18/kWh, removing that load would avoid 0.005 × 16 × 365 = 29.2 kWh, or $5.26 a year before the smart plug’s own use. Those are hypothetical inputs, not P110M test results.
For sensitivity, assume the smart plug itself averages 1 W throughout the year. This is an example assumption, not a specification: 0.001 × 8,760 = 8.76 kWh, costing $1.58. The modeled net benefit falls to about $3.68 per year. Substitute a verified self-consumption figure and your actual schedule before deciding.
If an illustrative allocated purchase cost were $12 per plug, simple payback under those assumptions would be about 3.3 years. This is not a current Amazon price. With only 1 W of avoidable standby over the same 16 hours, the modeled device saving is smaller than the assumed plug overhead. For the general method, see standby power worth unplugging.
A useful first-week trial
- Choose one non-essential device whose instructions permit external switching. Keep its normal schedule for the baseline.
- Record the dates, cumulative kWh and what the connected equipment did. Keep watts separate from energy over time.
- Introduce one schedule change, then compare similar days. Note weekends, extra work hours or other differences.
- Verify that restoring power behaves as expected while you are present. Do not assume a device resumes safely or that an app command is a physical safety disconnect.
Do not remotely cut power to equipment that must remain available or complete a controlled shutdown. Convenience should not create data loss, interrupted maintenance or unsafe operation. Off-peak scheduling changes cost only if your tariff actually varies by time; it does not necessarily reduce total kWh.
Who should buy it, and who should choose differently?
| Decision point | Practical meaning |
|---|---|
| Consider it | You want ongoing records and permitted scheduling, have suitable Wi-Fi and will use the information. |
| Choose a local display meter | You want occasional measurements without app setup; compare the P4460 below. |
| Keep your existing switch | The load is easy to control manually and automation has little practical value. |
| Wait for confirmation | You need a specific Matter energy feature or have an uncertain motor/electrical load. |
Check the total delivered cost, pack size and return conditions at the retailer. We do not promise a saving or publish a fixed price. Read whether an energy-monitoring smart plug is worth it before deciding how many, if any, to buy.
