Error on startup with the updated version

[steepleian]

Hi,
Firstly, thanks for this extension. I am attempting to set it up to use the SDS011 particle sensor in conjunction with the weewx-sds011 driver.

Does this version have backward compatibility or is it purely Python3x? The reason I ask is that it is throwing the following error at startup: -

I ran 2to3 on the code and changed litre to liter because the spelling changed between WeeWX 3.x and 4.x. So it's Python 3.

Try this release for python2 support:

Thanks Jonathan,
I picked up the spelling difference last night and pleased to report that it cleared the error.
A question. I am using the UK DAQI. I notice that the category columns are all populated in the aqi.sdb database with zero. Is this correct? I am still getting a background colour but as the readings are at index 1 at the moment have yet to see if this will change when index increases. Am I correct in thinking the category is linked to colour or is it different for DAQI.
Thanks
Ian

To save confusion I will move the database discussion to a new issue.
