On a side note, it was total serendipity that I found the excessive battery reporting thing.
I was in the logs looking for something else and found that.
A search on the forums indicated a firmware upgrade would fix.
Two of my three ZEN34's were at 1.01, while the third, and probably newest one, was at 1.4.
I did notice that z-wave would hiccup once in a while, but figured, hey that's z-wave.
Then, there's the wrinkle of probably pressing the up button only six times instead of seven!
An amber (to me-I'm partly colorblind) starts flashing. I didn't bother trying to see what that did-the button still did what it was supposed to, and that's good enough for me!
That seemed to help on the second one.
I was still pretty quick on the trigger though, because the blue light still went off quick, so who really knows?
Disabling the device is a good idea anyway: the first one turned on/off all the lights in the house and the second one turned open/closed a valve.
Of course, I'll have to remember to re-enable it, lol.
Looks like I shot myself in the foot.
I turned re-enabled it while it was still updating.
Now, it looks like it's permanently disabled.
Will be restarting hub shortly, lol. That's my go to move.
Yeah, leave it disabled.
Also, you may need to power off the hub and the device to clear the zwave radios before it will work again. I have had that happen before if they get stuck part way through.
Luckily, it was only uploading the file to the device not flashing it, so the device should be unharmed.
Some of the Zooz devices will factory reset themselves (or clear the lifeline association) after a firmware update. That may have been what happened on this one, maybe because it went from an old version. Usually does not happen on the newer devices anymore, I think they realized it was overkill and annoying.
