After what felt like years of silence from Zemismart, I finally got some new toys from them. Time to see if they’re any good.
Smart switches aren’t exactly thrilling these days, but this one caught my eye: the SRS01-P2TW. It’s Wi-Fi and works with the Tuya or SmartLife app—I already had SmartLife on my phone, so setup was easy.
I plugged it in using one of the live connectors and the neutral. No load attached yet—most switches today max out at 10 A, and Zemismart are honest about that on the box.
If you plan to use inductive loads, stick to 6–7 A. If that sounds like Greek to you, don’t wire it yourself.
Power on, I tapped “Add Device” in the app… and almost instantly, the switch appeared as SRS01-2PM (Power Monitoring). It has both Bluetooth and Wi-Fi, so it can connect before you even enter your Wi-Fi details—handy, but not revolutionary.
From there, setup was smooth. The app shows two on/off controls, plus buttons for “All On,” timers, electricity usage, settings, and “All Off.”
Buttons light up when active, and the consumption page tracks today’s kWh, current, power, voltage, and total kWh.
The settings menu is surprisingly detailed, with timeouts and other options for those not using a full home automation setup.
Next, I added the device to Home Assistant via the Tuya integration. A couple of clicks later, and the device appeared—no fuss. The image on the left shows how the SRS01-2PM appears (as a device) in Home Assistant settings.
A small bi-colour LED on the unit can be controlled via the app or turned off entirely.
Local control is possible by connecting wall switches to the S1 and S2 terminals. Unlike some Zigbee switches or Sonoff’s “magic switch,” this one requires a neutral, which not every wall socket has—but that’s fairly common.
So far, so good. It’s a small device, similar looking to many others of its kind and it does exactly what it promises—no drama, no surprises.
Nice little unit. I had planned to test the flow meter (in the lead photo) next but we’re moving shortly and as the council have just fitted a new sealed “smart” water meter it’s not that easy to get to the piping – so that review will have to wait.
