Aeon Labs ZW100 reporting odd temperature reading

Configuration Z-Wave
1

Hi,

I’m not sure when the change occurred but I noticed tonight that my ZW100 multi sensor is reporting a temperature of -3276.8C. The other sensor values also don’t look quite right to me, although not so wrong as to be as obvious as the temperature.

Is there anything I can do to address the issue or, mores to the point, has anyone ever seen a similar issue?

Thanks

Pete

HI,
Yes I get this issue occasionally with the 6IN1 units, I get it more often with the 4IN1 units (DSB05), so the workaround I use is to use grafana and put a max and min on my charts, so out of bounds values like this don’t make the chart unreadable.

Not ideal, but it works for me.

Same here. I use this strategy to get around it:

I run two HA instances: One small slave instance for the Z-Wave network only and then I pull all the entities into the main HA instance with the “home-assistant-remote” custom component. The reason is, that this allows me to restart HA, without having to restart the Z-Wave network, which sometimes takes up to 15 minutes. Anyway, that component allows it to define min/max values, which I use to get rid of the problem.

I had that issue a long time ago. I can’t quite remember what fixed it but I think it was upgrading the firmware on the multisensor

FYI with the new OZW Daemon (which will replace the current Z-Wave integration soonish) you don’t need to run a second HA instance for the Z-Wave network, you can install the OZW Daemon to the Pi and it then communicates to HA over MQTT. I’d advise you to take this tep sooner or later as the old integration is going to be deprecated. If you are interested, I wrote a guide here.

I am aware of that, but last time I checked it didn’t seem ready yet. Do you know of any document/page that shows, which features have been implemented and which have not?

7

What features are you looking for or is it more about device compability?

8

Nothing in particular. More like getting a general understanding how usable it is right now.

Thanks for the information and apologies for the long delay in replying.

I’ll start by checking the firmware version and updating if needed.

Peter, did you figure this out?

I have just migrated my ZW100 from Vera to ZwaveJS, so I don’t know if the erratic temperature reporting problem remains.

But I have had it running through a outlier filter for a while now, which helps to a point.

- platform: filter
  name: "Filtered ZW100 Sensor"
  entity_id: sensor.temperature_sensor_zw100
  filters:
    - filter: outlier
      window_size: 6
      radius: 10.0

Unfortunately, it does :frowning: Even on the latest FW.
