I have a simple iot app:

raspberry pi 4
aeotec Z-stick7
aeotec aërQ temp/humidity sensor
mosquitto
zwave-js-ui

The setup works fine, yet state changes are not being reported so often.

Yesterday evening, circa 23:00, the sensor reported 22.7 degrees to zwave-js-ui. This morning, circa 08:00, 19.2 degrees. No reports in between.

These measurements are accurate, however, the temperature will have fallen gradually during the night (the sensor is placed near a window that was opened partially at around 23:00 and the outdoor temperature sank till circa 8 degrees last night).

The log in the zwave-js-ui webapp registers no events between 23:00 yesterday and 08:00 today.

I'm guessing I need to tweek the parameter [3-112-0-1] Temperature Change Report Threshold?, which appears under Control Panel -> Node -> Configuration v4

But to what?

I'd like reports at least every degree of change.

It's worth pointing out that I get reports if I quick push the button on the sensor.

I found this post https://github.com/zwave-js/node-zwave-js/issues/2595, suggesting that this was an issue on older versions, called zwavejs2mqtt. The issue was unresolved, closed as stale.

    maybe the 0.1 is incorrect and is in reality 1.0 ... try setting the threshold to 1

  • Yes, that seems to help; i'll monitor a bit more this evening then repost here. Do you want to make it an answer I can accept? Or I can do it later.

Perhaps there is an error in the software, and the resolution is not 0.1, but it is 1.0.

Setting the threshold to 1 may reveal such an error.

  • This solution worked on my Ubuntu 22.04 laptop. However, on my raspeberry pi (debian) the zwave-js-ui interface will not save the parameter when I change it to 1. Highly frustrating. It's the pi that will be the "production" machine. I wonder if I set the parameter to '0' (disable) this will allow the device to report all changes?

  • Now also working on my pi; seems like I have to save the setting 2-3 times for the software to work out that I'm serious about this :)
