MR40Z Minoston: Frequent Updates from a Battery Device

Configuration Z-Wave
1

I have a battery operated MR40Z Minoston / S2 Remote Control Switch. Every so often I notice a flood of “Last Seen” messages in the log book. I’m trying to understand why I’m seeing them. They do stop after a while.

As a battery operated device I would not expect it to be sending updates frequently. But, the battery level isn’t really dropping much, so I’m wondering if the device is actually sending data.

The ZUI logs show the following. But I’m not clear if that indicates the device is sending its battery level or if (somehow) ZUI is generating it.

I don’t think it’s configuration:

Can anyone explain what’s happening?

Thanks

My guess is a firmware bug. I have a Zooz ZEN34 2-button scene controller and it has the same problem. Has happened twice now, and both times Zooz’s only response has been to suggest a factory reset, which solves it temporarily.

The behavior is the device reports battery levels for a couple hours anytime it wakes up, or you press the button. It only took a few days for the battery to deplete 50%, then less than a week to go to 0% even after the factory reset. This switch is only used once per day, and I extended the wake up time to the max (once per day).

I think I’ve seen similar issues with one of my Zen34 devices.

Is there an explanation of how to read that zwave-js output? I’m not clear what SERIAL represents (or if it is useful to me), as well as what CNTRLR and DRIVER represent or differ.

Thanks,

They are just the logging component names. SERIAL is serial data.
