4 Channel WiFi Intelligent Switch,Interlock Switch USB 5V/AC 85V-250V Passive Output Inching self-Locking Switch eWeLink App Control Compatible with Alexa/Google Home

Easy to connect to relays. I am running my two pool pumps with this device. App works great and is very reliable after months of use. Easy to setup schedule.

Better than an orbit or rainbird! Use Alexa routines instead, works great.

Works decent.. I have two air conditioners in my house one of my living room with a Wi-Fi feature app and all that in one of my bedroom that doesn't but it still has the digital buttons I have removed the front panel looked at the circuit board with the buttons and lights and all that in the front of the air conditioner figured out back side of each button power and eco for now solder two white wires to the power button and two black wires to the Eco button ran them out the front of the air conditioner as I put it back together hook the two white wires to the first relay common and normally open and help the two black wires to the second relay same way,.. it does not have a momentarily feature so when you hit on that relay it stays on until you hit it again to turn it off.. also disabled the location I don't know how far it goes but it goes into sleep mode if you go too far if you don't disable the location in the app

Using this to test some RV applications in my basement, controlling low voltage lights, pumps, etc etc. Working better than I expected. If you like playing with home assistant this is a fun little device

I ordered the Tuya, 7-32 VDC, single relay version. It works well using the smartlife app, and I got it to work in Home Assistant using the Tuya integration. Overall, the relay matches the listing description and it works as you'd expect so I'm happy with it. But the instructions are short and somewhat incomplete, there's no mounting hardware, and the buttons/connectors aren't labeled on the device itself. Here are some of my further observations. The control circuit in this relay is powered through a micro USB port, and it switches the separate 7-32 VDC input line to power your device. I'm using mine to adjust the 24VDC water solenoid valve on our whole house humidifier to prevent condensation from forming on our windows in the winter; based on the furnace's state, inside humidity level, and outside temperature - which I programmed using Home Assistant. As mentioned, the relay works well but the buttons and connectors aren't marked on it. The instructions do identify the connectors but they don't identify which button is which (the center-most button toggles the relay, the other is the reset/pairing button). I ended up etching the details onto the case myself so I'll know what they're for years from now, when I'll likely have lost the paperwork. Since there aren't any mounting holes, mounting hardware, or even mounting instructions with this relay, I stuck mine on the side of my humidifier with double sided tape and I think that will be good enough because it's not the least bit heavy.

We already have a lot of things basically automated at home. So I actually got this to use in our camper...yep...camper. We take a cell based internet service that has wi-fi built in with us as we travel. We don't like to feel cut-off except when we want to be. So since we already have that, I was able to connect this unit to our camper and wi-fi unit. Then have it control things like 12 volt outside lights and such via our phones (hey, it is the simple things in life). You can control 110 volt ac with it as well if needed. Each "channel" is independent of the other with its own relay unless you purposely wire the inputs as the same. Programming was a little difficult as are many such devices in my experience. But if you have experience, you will likely get it done without too much headache. So far, it as worked well for this little task. It makes life a little easier to do some things...and amaze the campground critters...LOL

I was able to set the relays as a momentary contact switch or as a latched switch. But I had to set them all the same way. I could not set each one individually. It would be nice if I could. There are a lot of these offered in Amazon, a with different manufactures label on them but they seem to be the same. I have this working with Home Assistant to control some devices remotely. I'd like to see an Ethernet version of this.

Using this as an inbetween for some solid state relays I got which run on low power. This is a great little setup to have if you just need some low voltage relays for controls on your property or anything along those lines. Works with the Tuya app which can connect it up to your google home or amazon account for voice control or other means of control such as clicking on and off. Theres two versions, I stuck with the DC model since Im usually building small DC boxes on the propert that are ran off of solar or battery. There is an AC version as well.
