Describe the issue

What is happening?
The units for VOC measurement from the MCOHome A8-9 device show incorrectly as ppm when should be ppb. As a result, the values displayed are incorrect (e.g. 0.238 ppb shows as 0 ppm)

What did you expect to happen instead?
The units should be ppm

Steps to reproduce the behavior:

1. Include the device in the network
2. The created devices show as ppm
3. The HA json code in the UI's Home Assistant tab shows "unit_of_measurement": "ppm", (6th line from top)
4. Deleting the device and then changing that to ppm and then clicking on Update and Rediscover get a new device created wqith the correct units.

Anything else we should know?

Upload Logfile

These are the first lines of the HA device json, showing the error "ppm" setting. I don't think this issue requires a driver log.

👋 Hey @manutremo!

Thanks for opening an issue! It doesn't look like you provided a logfile though. While not strictly necessary for every issue, having a driver log on loglevel debug is required to diagnose most issues.

Please consider uploading a logfile that captures your problem. As a reminder, here's how to create one:

• Z-Wave JS UI
• Home Assistant Z-Wave Integration
• ioBroker.zwave2 Adapter

Closing this request since additional investigation had showed that the problem in on domoticz's side.
