SONOFF RE5V1C - 5V WiFi-puls-/självlåsande relämodul

Tiny thing, but the inching mode is exactly what I needed for my door lock — set it once and it pulses perfectly every time. The LAN control without internet is a lifesaver too, since my wifi drops constantly but the relay still responds instantly.

Honestly didn’t expect something this small to switch so cleanly—the inching mode responds instantly every time I test it. I’ve got it running off a 5V adapter and it barely sips power, plus the LAN control still works when the internet drops, which is a lifesaver.

The 5V input makes it super easy to wire up with a spare phone charger, and the dry contact output is perfect for my smart door lock. Even when my internet goes down, the LAN control still lets me trigger it from the app, which is a lifesaver.
