Trying to automate my gate opener

Hi @Sirhc,
I use Shelly Uno's to detect the status of my garage door openers (after I had good feedback on another discussion. Afterwards I found confirmation in the Shelly community that at this moment, Shelly Uni is the only Shelly device that can measure a status (0 or 1) based on an external voltage. I am by far an electronics specialist, but it has been working fine all the time...
