Actions with timer option

Hi

I want to turn on the garage lights when I open the door and turn them off after automatically after 40 seconds.

I have a Shelly1 on my garage door and I want to control the garage lights that are connected to a Shelly2.5

When I set the action on the Shelly1 I cannot save the option timer.

Shelly1 - On the Actions I enable the "BUTTON SWITCHED ON URL" and add http://[shelly2.5 IP]/relay/0?turn=on&timer=40

I save and when I go back to the Actions menu, I only have http://[shelly2.5 IP]/relay/0?turn=on, the &timer=40 option was removed .

Everything works fine without the timer option, but I would like to have it (firmware 1.9.4)

Regards

Thank you for the advice it worked just fine. 👍

Now the lights turn on when I open the door, but also when I close the door.

How can I solve this situation, because I only want the light to turn on when I open the door?

The action is only on the "BUTTON SWITCHED ON URL".

I have a magnetic switch to know when the door is open. With this switch I also know when it is opening and close, because the status changes (opens Off to On) (closes On to Off).

How can I use this information to control the lights?
