Strange Triggers for PiFace...

[jadijkstra2000]

First I have my doorbell connected through MySensors, I thought it was stupid because the MySensors gateway is connected on my raspberry, 10cm next to the doorbell hardware... I used this in the past because the doorbell cable/button is to sensitive for PiFace2...and debounce was kinda difficult to do on the PiFace.... but wireless tranmitter over 10cm still is stupid, so I thought, well okay I will make a bridge with an arduino and a relay which I put in front of the PiFace2... so when someone hits the doorbell button, an arduino triggers a relay which triggers an input on the PiFace.

Again, this works like a charm... except... I have the following:

EventSystem/Afzuiging - Stand 3_1 -> I cannot understand where this comes from...and yes, sometimes the doorbell is triggered by "nothing" ...

And I see Open/Closed by Admin, EventSystem & Timer …only 1 should trigger…
