Review: Great addition to home automation/access control systems - I'm quite experienced at installing and configuring gadgets like this, but even so I was impressed by how easy this was. Perhaps because it's a single-channel, single-purpose device that doesn't try to be over-clever? Live and learn. Previously I've tried all-in-one boxes that do too much and don't do any of it particularly well or with any repeatable reliability. I particularly liked that setting up remote control key fobs is done with the help of the app, so there's no more fiddling about with tiny switches (or worse, shorting out two miniscule contacts on the PCB) while trying to decode what the invisible indicator LEDs are telling you. Just ask the app to enroll new remotes, and press the button on the key fob when prompted. Done. Love it. ## Features - WIFI app remote control your Garage Door opener light fireplace,Works with tuya/smart life app,doesn't support ewelink. - easy to setup with low voltage 5V 12V 32V,dry contact relay passive output,without voltage at output,only on/off signal at output contact.support 2.4G wifi only - Widely Usage,12V Google home with 2 work mode,change to inching mode in tuya app-timer,works as wireless emulate momentary button with inching mode.Close the inching mode,it will be toggle mode,works as wireless switch - Schedule and share control,create smart scenes,share control with family.you can customize the power-on state.
