Jumper is at 12V!
That was my intention, but I had second thoughts because I measured out that between SW and L(-) has 1/2 of sources voltage. So no need for any isolation?

Danke Schön!
Not quite what I was looking for. I was a bit unclear with my setup. The lock is Abloy EL581 and has a bolt with 2 states. It's either in or out.
Lock is already powered up from another circuit so basicly I just need a locking state (in this case NO (=Open) is enough). Shelly output goes to access controllers "open button" and it opens the lock.

Hello,
I have pretty similar setup with this:
Make Your Garage Door Opener Smart: Shelly 1, ESPHome and Home AssistantI've been adding more and more devices to my smart home lately, so naturally, my garage door opener had to follow. But instead of swapping it out for a new…savjee.beOnly difference is that I'm using 12 VDC and the input sensor is normally open information from the lock.
So I want to have lock state (open/locked) to Shelly, but I don't want to send any current to lock. Do I need like a optocoupler between lock and SW / L(-)?
Thank You!
