DieseRC 1 Channel WiFi Smart Switch DC 5V 12V 24V 36V Passive Output Relay Module Ewelink APP WiFi

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. Read more

This WiFi smart switch relay module has been exactly what I needed for my home automation project. Setup through the app was straightforward and took only a few minutes. The eWeLink app integration works flawlessly, and I can control my devices from anywhere with a reliable connection. The build quality is solid with good solder joints and quality components visible on the board. I've been using it to automate a fan in my workshop, and it handles the load perfectly without getting warm. The fact that it supports multiple voltage ranges (5V, 12V, 24V, 36V) makes it incredibly versatile for different projects. Response time is instant whether controlled via app or voice assistant. The compact size makes it easy to fit in tight spaces. Great value for anyone looking to add smart control to existing devices or DIY home automation setups. Read more

Perfect . . . Hand shake with WiFi network was not a challenge at all. Just follow the instructions. Using on my sprinkler controller (normally closed side for the common wire). I had a bunch of mini usb power supplies so not an issue there. Literally took 10 minutes to setup the app, the wifi connection and the hard wire pigtail for the common wire. To test I had my wife watch the relay and I drove a few miles away with her on the phone. Perfect. Read more

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. An image is attached of this great little product installed in my ENEL Juicebox Pro40 EV Charger. Read more

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. Read more

I purchased a Chamberlain garage door opener years ago and just installed it, only to find out the logic board was defective. I could not pair a MyQ device or even the enclosed remote button to operate the opener. The opener was so old, I could not even find a replacement logic board. Every vendor was out of stock. And, it would have cost me from $85 to $115 plus shipping charges. So, I bought this EW-1CH unit. It is very small. I used an empty plastic prescription bottle with a hole in its cap for the wires to house the unit. I powered it with a spare USB mini cable and a 5V power adapter. After downloading the eWeLink to my iPhone, I paired the EW-1CH to my phone and set the device to inching mode (momentary contact instead of toggling on & off) and used the default setting of 0.5 sec. For wiring, two wires went from the unit's common and NO (normally open) terminals to the two terminals on the opener where the wires from the push button were connected. Finally, I set up eWeLink in Alexa and created a routine so I could give Alexa a verbal command to operate the garage door. I am very happy with this purchase, especially the $ I saved. Read more
