Hi, guys.
I have my first 2×4 working well in its intended function, and am confident enough that I just bought my second unit, and will be deploying it in a week or two.
One oddity remains, though. Every now and then, I get a group broadcast saying that one of the inputs has changed. Within a second or two, I get another saying the input has changed back. I spent quite a bit of time making sure my contacts weren’t really wiggling around or too far apart, etc. Finally, in order to eliminate the contacts or wiring as a possible problems, I removed one of the contacts entirely and just hardwired it “closed.” I still get the group broadcasts for this input.
If I query the device during the time between the broadcasts (gotta be quick!), I get back a reply, but the bitmask in Cmd2 is all zeros, indicating that all of the inputs are open. A moment or two later, I get the second broadcast, and a query THEN tells me that all the inputs are closed. So I think it’s definitely the 2×4 reporting wrong, not the wiring or contacts. Fortunately, even though the 2×4 thinks everything is open during this brief period, it only broadcasts about the first one.
When this problem started, it was happening 2-3 times a day, but recently it’s only been about once a week. It’s almost always the first dry contact that reports erroneously.
Any idea what’s going on?
