External Switch via AddOn

Is it possible to set the External Switch as detached? I am working out the best way to operate garage doors, and it would be great to be able to connect a magnetic reed contact to the External Switch terminal, as that would allow the icon in the app to show a garage door picture, and the word 'Open' or 'Closed', as required.

I know that I can use the standard switch input, with the state shown on the app button as a red or green bar, but it would be very nice if I can actually have it show 'Open' and 'Closed' text.

I've answered my own question.

A new checkbox has appeared, which allows the external switch to control, or not control, the relay.

Unfortunately, when I try to 'detach' the switch from the relay, with the app, it reports 'something went wrong'.

But! The web interface to the Shelly 1 does allow me to achieve my goal.

Thank you Allterco. But please stop adding features to the app, and concentrate on making it reliable and robust.
