Used to ‘Alexa’ my electric gates
Rather than look for the gate remote I wanted a single bolt free contact Alexa controlled relay small enough the fit in the gate controller box. This is it. Set it up with a battery in the house first, took a couple of attempts but that’s the same with everything Alexa generally. Moved it out to the gate controller box that’s around 30m from my house and the router is around 10m from the external brickwork of the house. Bingo. This thing is brilliant. I used an insulation pad for the rear of the board at it doesn’t come with mounts or pcb holes for mounting.

Surprisingly Easy Setup
Using it as a remote power switch on my PC, with the 5V line. App surprised me by connecting first time contrary to what I have seen in other reviews. Perfect.

Easy to install, enables you to control your 240v circuit from a 12 volt power source
This Wi-Fi smart switch, is such a good idea. It enables you to switch on and off a 240 volt circuit, remotely just using the 12 volt circuit of your camper van. This is ideal as it saves you I've had the 240 volt circuit permanently live. The switch looks to be quite well constructed, and it's clearly laid out. The switch itself was easy to install and can be hidden out of the way. The app is simple to use, and enables you to control the switch via Wi-Fi connection. You will of course require a Wi-Fi hub of some sort in the camper van to enable you to use this switch. That said it's still a great idea.

I've had it running a relay for my chicken coop door for a month now with no issue. Setup was super simple, the application is easy, the schedule works without issue, and it tied into Google/Alexa without issue. The ONLY downside I've had is that while it "works with" google and alexa it always turns on/off with the all/everything skill when I don't want it to. I've tried treating it like an outlet, appliance, and other, but it still changes status with the lights. This is a problem because it's opening/closing the chicken coop when I turn the lights on/off. Past that, this is a great little board.
