Shelly BLU Button & BLU Door/window - Shelly app + Home Assistant setup

I find this setup frustrating. I need these devices to fork a URL (rest) when a door is opened for example. So you create a scene and then an action, but an action has to be device, notification or scene. Device and Scene don't work because they a grayed out, notification has no URL options. I don't want to integrate wit HA, I just want to fork a URL with the id of the device in the post, so it can drive my home alarm system. This seems like a basic function.

Hej Er der begrænset rækkevidde på dørsensor Da jeg har en som ikke kan få til at virker og har forsøgt at flytte router osv Imødeser dit svar

Is it possible to switch power off with Shelly Plus 1 using this door/window sensor actions? So that when the door opens, the power switches off from Shelly Plus 1.

What a crap system, I will stay on wifi.

So this is without a Bluetooth dongle on the home assistant gateway and you are using Shelly Relais as a Bluetooth proxy?

Great vid thanks
