DieseRC 1 Channel WiFi Smart Switch, DC 5V 12V 24V 36V Passive Output Relay Module Ewelink APP WiFi Control Compatible with Alexa/Google Home, Inching/Self-Locking Switch

Used this four-output smart switch for a three zone drip irrigation system. The device powered up and was recognized by the app (eWeLink) quickly, then updated the firmware in a minute or so. I used the original drip system controls 24 VAC transformer to power this device. A wide range of options are available, as you can use DC 5V, DC 7V-48V, or AC 7V-32V to power it. The outputs are dry or passive, which means there is no voltage except what you provide. So I took the same 24 VAC power transformer from the original drip control and ran it to the "C" on the relay, so that when the device responded to an on command in the app the voltage would pass through to the "NO" on the device relay and activate the water valve wired to it for the zone. The other side of the 24 VAC transformer went to the white common wire from the water valves. All worked perfectly the first time. I purchased the four-zone device, but only used three, hence the three-zone drip system. Super value for $17.99. I can't speak for the long-term reliability, as only time will tell. Key points that make it great: Excellent voltage choices, DC 5V, DC 7V-48V, or AC 7V-32V. - USB or screw down terminal for voltage input. - Dry/passive output contacts.

So far so good. I have only had it a few days, but it was easy to set up and connect to Alexa. I like the small size because it fits into my raspberry pi project box and helps me use Alexa with my pi project.

Works great -- can be set up to turn on the connected device automatically when the power comes on. Integration with Alexa is seamless.

These switches work great for many applications where you need switching control over WiFi. There small enough to fit in most applications and very easy to install and use. I had no problem setting it up with the downloaded app from google store or Apple Store. I do recommend this WiFi switch.

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.

Out of 8 devices 5 stopped working within minutes. App identifies the device and then cannot add to the list. Device stopped blinking, not connecting to the Wi-Fi or connects and fails immediately. This happens even w/o external load is connecting.Wanted to remotely control several LED strips spread around the house. Bought a pack of 4 and a remote. First device works. Then 3 failed. Asked for replacement. Out of replacement package 3 already does not work.

This great little product was a simple yet Very effective fix to my ENEL Juicebox EV Charger Pro40, since ENEL decided to throw-in the towel on US & Canada product sales & support. This simple solution provided me to no longer rely on ENEL server-network to turn-On & Turn-off my charger at my preferred time-of-day. It also allowed me to control it from my Amazon Echo unit using Alexa voice commands & setup custom charge routines. This is a great product at a reasonable cost.
