DieseRC 4 Channels 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.

Works great in my wireless remote door lock.

Exelente Tim I love I just like do a pro yet invent circuit and work great thank you

Easy to setup with app. Control devices with phone. I use this to control (turn on/off) LED strip lights. Works as expected. Recommend.

Moved into my RV full time and wanted to be able to control lights with my Google home and app and this did the trick. Instructions aren't too clear but if you take your time you'll figure it out. Not sure if they make a case for this to be installed into but that would be a nice feature.

Excelente 👌

Intermittently connects to Bluetooth. Will not stay connected to WiFi despite strong signal. App is terrible. Should have bought Shelly.

Used in my car camper for operating interior lights, worked really well for what I needed, I will be working into the camper van when I get the time instillation wasn't too bad when I read the instructions properly,

Snabb leverans Enkelt att köpa Framför allt bra bifogad funktions beskrivning 👍👍

The 5v Dc supply would have been a issue so sent back

Fait parfaitement le job en contact sec, facile à mettre en œuvre et bien détecté en Wifi via l’application

Funzionare funziona e il controllo remoto va, ma alimentandolo da USB qualunque cosa gli collego (lampadine, piccoli motorini 5V) non si accende nulla. Purtroppo il tester ha smesso di funzionare nel momento sbagliato, quindi non so nemmeno se arriva corrente ai capi, ho provato il collegamento diretto da polo positivo a polo negativo senza passare per i vari NO ma niente
