SwitchBotSmart 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

It works, and it's good. Small, real Matter support. Better than Tuya things.The only problem is that it takes time to open the light from the app, because the guys who developed the app block your control until it gets the electric consumption. So don't get the P model, unless you really care about knowing the kWh usage.Also, this supports 1 switch only, so be aware that if you need to control more than one switch, choose the other ones..

I used this relay to make my pool lights smart and it works flawlessly, even inside the metal enclosure that contains all my the pool wiring and breakers. My router says the wifi signal is very weak, but this relay still works like a champ inside this closed metal enclosure and enduring Florida’s heat! This device is so great and reliable that now I am looking into other SwitchBot products for my smart home.If you are curious: I replaced the wired Intermatic manual pool lights controller with this little relay, not connected to any switch at all. This means that now I control the lights only using the app or HomeKit.

Bought this to have a contact closure input, which it does do splendidly. Except only for the load its currently operating and you can not disassociate that link or use the button press as a separate signal in your smart home controllers. It did however take my bluetooth curtain controller and make it shared as matter, which is awesome

Easy to set up. Multiple options for powering the device. Works great.

Easy to initiate into the Switchbot system. The contacts are dry. (Isolated) which greatly enhances the usefulness. Can be powered from just about any voltage. Contacts are rated at 16 amps but getting any conductor larger than 16 gauge in that tiny connection is a loser. Bluetooth lag time on activation could be an issue if you have a lot of other devices on line.

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.

If you live in an older home with old wires this will not work for you

There are already well established home automation protocols that have been in use for years, but this company decided to not pay any of that attention, and lead potential customers into thinking this will work fine with a SmartThings Zigbee hub, which it will not.So, just to humor things and verify it's even working, I add the switch to my SwitchBot (I use their little temp / humidity sensors) app just to see if I can live with switching them that way. All installed fine, but one of the switches were defective; 120VAC in just fine, the relay in the switch clicks as it is supposed to, but no 120V output whatsoever.Boxed 'em up and sent them back. There's another 1/2 hour of my life I'll never get back due to someone else's negligence in making a defective, terrible product.
