SwitchBot Smart Relay Switch 1,Smart Relay Module with Built-in Hub, Wi-Fi&Bluetooth Switch Compatible with Alexa/Apple Homekit/Google Home/Matter Hub Required, 2.4GHz, Home Automation

I wired it in conjunction with one of my led momentary push buttons, 28vac I think. You just need the 120 hot and neutral on the right terminals, then the 2 far left terminals are switched. I don’t think it matters, just the 2 low voltage wires either side. I think you can have it wired into the ceiling garage door opener, but I had an electrical enclosure to use. Good luck on getting Alexa and Siri shortcut to work. Really had to dig deep and figure it out. I did not have to download Matter, even though Alexa wanted me to. I think I only set it up on the, new to me, Switchbot app. Then I was able to get Siri shortcut, then finally somehow got Alexa to recognize the bot. I set the momentary switch duration in the app to the lowest setting I found(1 sec). I can now tell Siri to open the garage, so relieved. All my big garage leds come on when I get home from the Alexa arrival routine, which messes up my garage door clicker reception from my truck is mostly why I went this route if you are wondering. Don’t let the picture fool you, it really is small, might seem bigger in the pic. Just hope this helps anyone going into it blind like I did. Thanks.

I bought this to extend the Bluetooth range between my SwitchBot hub and sensors. I do not use the switching function. As a Bluetooth extender, it works flawlessly. I like the flexibility to use a variety of power sources. I attached an old 24 volt passive POE (power over Ethernet) adapter so I could safely hang it on the wall and plug into any nearby outlet. The instructions list several options for power inputs (100-240V AC; 12 or 24-48V DC). Wiring and setup were simple and its tiny size allows it to go just about anywhere. I'm not sure I would pay full list price (since I'm not using the full functionality), but significant discounts are frequently available. SwitchBot devices have been very reliable for me.

This should be a 5 star product but their decision to use 4 point type for the instructions makes the manual uselesss. Functionally it has been flawless. It was relatively easy to set up in the app and Alexa automatically added it to its device functions. I quickly added 4 more to my system for a total of 8. They activate/automate 12V lights in the RV, the remote switch on a gate opener, exhaust fans and low voltage lights. So far they have all operated exactly as they should. The less than 2"x3" instruction sheets are just silly.

I used this to control a device powered by 12V DC. Works perfectly and integrates with my smart home.

The relay switch is a smart little device! It's great. It allows you to turn on any plug or light into a connected device basically. Then it becomes integrated into Switchbot ecosystem (and because it's matter compatible, into the whole smart home system) and you can automate whatever it's connected to. I've got it attached to my foyer lights so they turn on when I unlock my front dooor. I'm not good with electrical stuff but it was pretty easy once I was able to figure out which wires were which. I will probably get another one to use for my garage door.
