[solved]Send only once when contact is opened

---

Hey guys,

I could use some help with a rather simple rule that I can’t get to work.

I have a wireless door contact (ID contact1) and I want pimatic-prowl to send one message when the door is opened AND (via pimatic-ping) two devices are absent.

My first try was:
contact1 is opened and iphone-1 is absent and iphone-2 is absent

but this sends a message every X seconds when contact1 is opened and the two devices are absent.

What do I need to change to send only one message as soon as contact1 is open?
I think I have to introduce a new variable (NotificationSent) that is set to true and to false once the contact is closed again.

Thanks for your help,
Dominik

i think if $contactname1.contact changes and and iphone-1 is absent and iphone-2 is absent then ... should do the work, because the rule is only triggered when the contact changes.
In the GUI rule screen you can find this function under “variable changes”.

Additional info:
Are you aware of that iphones disable wifi after some minutes? That would mean your iphones sometimes get absent but in reality they are still present. There are different ways to solve that. One would be to add another ShellPresence sensor and use hping3 to wake your iphone ever X minutes. See other forum.pimatic thread. I have to mention that this solution doesnt work at 100% of the time (read threads in the other thread). If you find a better solution let me know!

You might also want to add another attribute to your rule, so the rule is only triggered, when your contact changes from closed to opened. Something like if [see above] and contactname is opened then ... should do the work.

Hello,

adding “changes” actually did the trick, thank you!
I know that “pimatic-ping” isn’t the perfect solution but I’ll take that into account.

Best regards,
