Hello everyone, I have a garage door sensor that when the door opens is emits a 1-0-1 sequence of events in about 2 seconds, then when it closes the inverse 0-1-0. A steady 0 means the door is closed, a steady 1 means the door is open. The image below shows first an opening sequence, then a couple minutes later a closing sequence.
Does anyone have any suggestions how I can generate 'door opening' and a 'door closing' events from this state? Thanks in advance.
This example may help you The inject and split simulate your payloads.

I think the trigger needs to be 2.5 seconds, or thereabouts doesn't it?
yes you are correct i did not see the times on the image . maybe a second would do as the payloads seem a second apart.
[edit] 2 seconds should be fine

[edit] added per topic in trigger
That's really cool - many thanks. It works perfectly after I fiddled with the times a bit and landed at about a second in the trigger. I see you cut the logic to just looking at the last digit, rather than the whole sequence, which in this case should be safe. Good solution, many thanks
