Review: Outstanding and versatile smart 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.
Review: Is a great circuit to adapt to any equipment.. I did I love 👍👍👏👏👏🫵💯💯 - Exelente Tim I love I just like do a pro yet invent circuit and work great thank you

*by B***D on April 29, 2024*

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.
