Thanks ! Don’t worry, I’m mainly trying things on my new raspberry pi 2W. I will try to reinstall everything to see if it helps
Hi @junelac . I’ve been able to reproduce on 4.2.1 (doesn’t happen for me on 4.2.0).
I have a fix out here:
Thanks ! I will try it and give you my feedback as soon as I can
just to be sure: the changes are not yet available in the official add-ons (marked with a blue chck mark) ?
I’m not sure if the blue checkmark takes the latest from the source code, or if it needs a new release of openhab to take effect.
I have made a jar available, which can be copied into the addons-folder to take effect if you want to try it out:
thanks, the addons works now !

So Jan 6/2025, I received my four brand new I-9PSL and my O-1PST. I immediately hooked up and flashed them to 3.1.13 had them integrated reporting on the dash board within the hour, and had them in my Openhab instance by morning… WOOPS, discovered there was no NOx sensor Channel in the openhab binding, only a NOX recalibration one… ok… TVOC worked fine raw was a confusing number but it was there… . fast forward 2 weeks… the firmwares now read 3.1.21 on all four (been way to cold to install the outdoor one yet) and the TVOC channel no longer shows up in openhab binding… So I assume somewhere between 3.1.13 and 3.1.21 the output of /measures/current changed breaking the openhab binding, The values in the PM also changed as well somehow, as now I had to rewrite my display widget to automatically calculate the PM1, PM2 and PM10 (sorry wasn’t watching PM) values to get them to match betwixt the units display and the openhab… website doesn’t mention the apparent 7 minor releases since Jan 6. There seems to be rampant breakage in the offing at the firmware level. Any way I can help to update the binding, I’m willing.
Thanks! I also finally got my logging issues resolved and started seeing the following in my logs, but this could be my meddling with the things linked to the channel:
Failed to update item 'airgradient_34b7daa1e394_Particle_Count' because '488.33' could not be converted to the item unit 'kg/m³'
If this happens to make more sense to you, I look forward to fixing it…
It would be really nice, and if we had a TVOC_Index and NOx_index channel too so I can finish my widget that mimics the airgradient I-9psl oled screen
Hi, yes, I am working on it. These are the values I’ll be able to fill out for 3.1.21. I expect to have something ready during the weekend.
Super awesome… if you need anything please feel encouraged to reach out and I’ll assist however I may, Even if I need to ship supplies, you know cheetos, pizza, soda, etc.
A screenshot of the widget with data is all I need 
The warning above for a particle count converted to kg/m3 sounds like you have a item for e.g. pm003-count (which is just a dimensionless number in the system), but trying to convert it to kg/m3. I’m not sure where the conversion happens, but try to look at the item - metadata - unit. Maybe that is configured strangely?
It is getting late here, but I have something that works on my local OpenHAB 4.2.1.
I created a prerelease here, and you should get more data if you copy it to your addons-folder:
I added a sources jar so you want to see what I have done. I’ll create a proper release of it tomorrow.
Oops. sorry. life went nuts. The village idiots banded together and elected a felon… Here’s the widget code:

at some point I’ll get time to figure out the apropriate vertical and horizontal lines to separate th8ings…
Cool widget! I have no idea on how to correctly get those borders in there, but I have sent out a pull request on the changes I added.
