Shelly Wave i4 DC

Wired this to four momentary switches to trigger scenes without touching my phone, and the response is instant every time. It runs on DC power so I tucked it into a din rail box next to the panel. Setup through the gateway took a few tries but that was on my end.

Using the four digital inputs to fire off my kitchen lighting scenes, and the response is instant every time. Setup took a few minutes once it paired with my gateway, and now one button press runs the whole sequence.

Wired this to my garage door contact and a couple of wall switches, and the four digital inputs handle all of them without any lag. Scenes trigger the moment a contact opens, which is exactly what I needed for my automation.
