ZW100, Multi Sensor 6 - Motion Auto Off/ON Problem

Tags: #<Tag:0x00007faed939cda0>

Hi All,

openHAB version: 2.5.0 - also tried on 2.4.0
running on Raspberry Pi

I got a new zw100 this morning and the issue that I am seeing is that whenever the alarm cancels it automatically goes back to ‘ON’ a few seconds later. Has anyone seen this or know what could be causing it. I have another one that I got about a year ago that works just fine.

Thanks in advance,

This is the device.

I see configuration parameter 4 sets the motion sensitivity and the default is maximum sensitivity.

The sensor may be detecting other motion.

Thanks for the link. It was initially set up higher but I changed it to 1 - minimum sensitivity and didn’t notice a change in behavior.

Did you wake up the device so it actually received the configuration? (assuming you are running on battery).

Yes I have. And don’t see any ‘pending’ notifications in Habmin.

I think that you need to adjust the “Motion sensor reset timeout” to 10 sec. As far as I can see from your log, there is around 60 sec. between the “Off to On” and “On to Off” which is matching your current value of this parameter.

The 60 seconds timeout is for testing. That part is working fine. Will up to 4 minutes like the other one when I figure this out.

It resets after 60 seconds (normal) but then 2-3 seconds later it fires back to ‘On’ as if it detected motion when it hasn’t. The log above shows the consistency of the behavior.

My theory is that the device remembers a motion and sends it after the reset.

Just because “kitchen” was mentioned - I expect you know these things will be triggered by e.g. a hot air vent or heated air plume from an oven etc.
