SwitchBot Smart Relay Switch 2PM, Power Monitoring, Smart Relay Module with Built-in Bluetooth Repeater, Wi-Fi&Bluetooth Switch Works with Alexa/Apple Home/Google Home/Matter Hub Required, 2.4GHz, 16A

I've been slowly but surely turning my home into a smart home, and the garage door was one of the last holdouts. This SwitchBot switch caught my eye, and it has genuinely worked wonders!The installation process was relatively straightforward, connecting it to my existing garage door opener's wiring – if you're comfortable with a bit of DIY electrical, it's manageable, but if not, a professional could do it quickly. The real magic happened once it was set up with my smart home ecosystem (I'm using Apple Home, but it works with Alexa and Google Home too, and Matter compatibility is a great future-proofing bonus).Now, as I pull up to my house, I can simply tell my phone's assistant, "Hey Siri, open the garage door," and poof, it opens hands-free! No more fumbling for remotes or punching codes, especially when my hands are full. The power monitoring feature is also a neat bonus, letting me keep an eye on usage. The built-in Bluetooth repeater ensures a solid connection, and it runs on 2.4GHz Wi-Fi, which is standard for most smart devices. This little relay switch has added a huge layer of convenience and efficiency to my daily routine, making coming home a breeze.

I got this expecting to wire it into my outside light switch to control it with Alexa, switching it on at dusk and off after I get home.Upon reading the instructions and investigating my lighting circuits, I realised I had no third wire to my switches, so would have had to put it directly into the light fitting. A task impossible for me, as it was simply too small for even this tiny piece of kit.I did look at the app that sets it up and controls it. The instructions mentioned needing a connectivity hub of some description, which I don't have. Slightly confusing, as other reviews said you could connect it directly without a hub.I might get an electrician to have a look at it and see what they can do next time I need work in the house. For now, it'll sit on a shelf and gather dust.

This is a tiny bit of kit packed with useful functions. Not only is it a two channel switch but it also incorporates power monitoring. It does need a neutral so if you're a UK household with loop in wiring you can't fit it behind a light switch easily.This is really versatile in that you can connect it to an existing Matter compatible smart home like Smarthings or Homekit - I connected it directly to Home Assistant without any issues. It also connects directly to its own app via WiFi if you don't have an ecosystem to connect to so no need to worry about buying a hub or similar.In operation it is responsive and reliable - I've not had it drop out or 'go missing' in the couple of weeks it has been in use operating my external plug sockets.

The price is £26.99 at the time of review and while it is good value for money, it can be lower compared to other similar products on Amazon. Glad I ordered as it has been useful, but maybe a bit of mixed feelings. This product is suitable for those who want to automate two circuits—like lights and fans—without rewiring everything. Its main functionalities include remote control via Alexa/Google Home, energy monitoring, and creating custom automation scenes through the app. You can even pair it with sensors to trigger actions like turning on lights when motion’s detected.What I loved most was how the build quality is solid—the V0 flameproof casing feels sturdy, and the 16A rating handles heavy loads without heating up. The ease of use is decent once you’re past the initial setup; the app’s energy graphs helped me spot which appliances were draining power. On the flip side, the instructions are vague—I had to watch YouTube tutorials to figure out wiring, especially since my older switch box lacked a neutral wire. Also, the 2.4GHz Wi-Fi requirement caused hiccups until I moved my router closer.If you’re intending to buy this, then I’d advise to consider whether your switch box has a neutral wire and enough depth—mine barely fit, and I had to adjust the wiring. Double-check compatibility with your smart home setup (Matter support’s great, but some hubs might need tweaking). The copper-nickel contacts are reliable, but if you’re not comfy with basic electrical work, maybe get a pro to install it. For the price, the control are neat, though the app could be more intuitive. If your priority’s long-term energy savings over plug-and-play simplicity, this’ll do the job.

This unit operates much like the other variations of relay switch you can hide behind a lightswitch. Itself the unit is tiny and just a little larger than the single relay Sonoff MiniR4's.The unit supports matter although I don't currently have a hub to test this. For now I've been using the mobile app to control the lounge lights via bluetooth which works well & shows the power being consumed when switched on.Ideally I wanted to use this with Home Assistant but the double relay version of the switchbot we have here is not currently supported unlike the single relay version. Their site does show that this functionality should be available this month (May 2025) so will wait and see.For those that may want to install ESPHome the device is an ESP32-C3 connected to a HLW8112 power monitor and has connection points to all the standard programming pins which can be accessed by removing the bottom cover which is held on with a few clips. One thing I'm not sure about is if the chip is locked down at-all...
