I'm not so sure what to do next and how to move on. Tried every possible angle but I simply can't seem to get a doorbell driven blockly event to run stable. Occasionally it is fired but most of the time it is not. In the log I see the below:
2018-01-25 20:15:59.547 RFLink: 20;6D;ElroDB;ID=141c85d3;SWITCH=1;CMD=ON;CHIME=01;

Although it is the same doorbell that was pushed a number of times you can see in the log that sometimes it shows as ID 141c85d3 and on other occasions it shows as de0ed593. This seems weird to me, but none the less, I have added both ID's as a doorbell. And although the log states that both ID's trigger the event "EventSystem: Event triggered: Deurbel_1" nothing happens.
I have broken down the event to as little as:
if Deurbel1 != Off or Deurbel2 != Off DO --> Write a message on the log "There is someone at the door".

First I started out with IF Deurbel1 = On but clearly, that did not work. So based on earlier posts I found on this forum I changed that to not equal Off which seemed to work for just one time. I don't know what is causing the event to trigger but does not seem to work.
Do any of you have some pointers on where to start looking?
