ZOOZ ZSE42 v1.0 w/ 700 Chip difficulties

[GJ Software Products]

I've had 1/2 dozen or so if these devices for a couple years now, they all used to work fine, but now at 5.8.4 the behavior has gotten strange.  The other day one triggered when it detected moisture, then testing the others they did not trigger, they wake up when they feel like it, I excluded and re-included, they came in as a wake device(maybe just saw the one property?), I continued to fool with them, one after I had the battery out for ~! hour, let me include it in as a leak detector, it worked for a bit, but then it stopped working after I ran it through a few wet/dry cycles.  Has anyone else had recent difficulties with these ZOOZ LSE42s?  Got any recommendations?  Thanks.
