How to close the Shelly contact for a given number of milliseconds and then to reopen it
Hello,
I would like to use a Shelly 1 to trigger the opening of my garage door. 

To achieve this, I just need to give an ON signal to the garage door board. This signal  that should last some milliseconds, in other words I have to close the Shelly contact for these milliseconds and then to reopen it.

How can I achieve this with the plugin? I am missing this!

Thanks for helping, 
Dan
