Rule to trigger only once on a certain time
I am trying to include on my Zipato an existing intercom for the entrance door. I have added a Fibaro multisensor to it for that purpose, which is detecting properly the existing call signal needed. What I want is to send a push message when someone calls.
My problem is that this intercom sends activation signals not once, but several times each time someone calls (the signal goes OFF->ON->OFF->ON... several times). So I am receiving more that one push message for each call.
I am trying to build a rule to take in account only the first activation and ignore the rest for certain time 120 seconds). But the rule is not working properly and several messages are sent.
Could someone help??
