The Shelly Plug M Gen3 is a Type F plug for European Schuko and Type E outlets, while the TP-Link Tapo P125M is a Type B plug for North American sockets. The wall you have decides between them before any spec does.
The Shelly Plug M Gen3 switches up to 3000W at 13A on a 220 to 240V supply. The TP-Link Tapo P125M handles 1800W at 15A on 100 to 125V, enough for a heater but a lower ceiling on a European circuit.
The Shelly Plug M Gen3 carries a voltmeter, an ammeter and power and energy meters, so it reports what the appliance draws. The TP-Link Tapo P125M is a plain on-off plug with no metering at all.
The Shelly Plug M Gen3 carries a three-year warranty and stores schedules, timers and local actions on the device so they run without the cloud. The TP-Link Tapo P125M backs its plug with two years.
Both are Matter-certified and reach Apple Home, Alexa, Google Home, SmartThings and Home Assistant. The TP-Link Tapo P125M leans on Matter alone for that reach, while the Shelly Plug M Gen3 adds the official Home Assistant integration and an open local API.
The Shelly Plug M Gen3 has a built-in voltmeter, ammeter and energy meters the TP-Link Tapo P125M does not.
The TP-Link Tapo P125M is built for that standard, while the Shelly Plug M Gen3 is a Type F plug.
Its 3000W and 13A rating gives more headroom for high-draw appliances.
The TP-Link Tapo P125M is the more affordable of the two and a full 15A plug for the price.
TP-Link Tapo P125M owners keep returning to how little there is to set up: they plug it in, scan the QR code and are finished, with several noting they never installed a vendor app at all. Reliability is the second theme, since buyers who had grown used to plugs silently leaving the network report this one simply staying connected, even through short power cuts and, in one case, an outdoor lighting box through a Canadian winter. The compact body comes up repeatedly because it does not block the second socket, and the physical button earns its own mentions. Their warnings are that Matter needs a controller already in the house before a third-party ecosystem can see the plug, that there is no energy monitoring, and that one early buyer was steered wrong by the quick start guide during onboarding.
It depends on the socket. The Shelly Plug M Gen3 is the better plug for a European Type F outlet that needs energy metering, more load capacity and a longer warranty. The TP-Link Tapo P125M is the better pick for a North American Type B outlet where a simple, cheap Matter switch is enough.
No. The Shelly Plug M Gen3 is a Type F plug for European Schuko and Type E outlets, while the TP-Link Tapo P125M is a Type B plug for North American sockets.
No. It is a plain on-off plug with no metering. The Shelly Plug M Gen3 is the one of the two with a voltmeter, an ammeter and power and energy meters built in.
The Shelly Plug M Gen3 handles up to 3000W at 13A on a 220 to 240V supply, and the TP-Link Tapo P125M up to 1800W at 15A on 100 to 125V.
Anyone on a European socket who wants to meter a high-draw appliance, run local schedules without the cloud and get a three-year warranty.
Buyers on a North American outlet who want a compact, inexpensive Matter plug that leaves the second socket free and does not need to measure power.
