#1

I just installed my refurbished Garadget unit. No issues connecting to my wifi and I have a pulsing cyan LED as expected. I believe I have the unit wired correctly to the first two connectors but its not working consistently. It will open the garage but it will not close it. If I short the 2 wires with a screw driver the door opens or closes as expected.


#2

What Garadget does to open the door is exactly the same thing that it does to closed it - momentarily shorts the connected terminals simulating push on the button. Is there a difference if you wait for short time after opening garage before attempting to close it?

You can try increasing the push time from 0.3 to 0.5s.

Finally got it to work. I ended up having to adjust the Relay On Time to .7 seconds.

Thanks!
