AirGradient API Binding

Many thanks from my side too for the binding.
I would have some newby question to the AirGradient configuration:

I’m using the local web access (currently also pushing it to the cloud, but plan to stop that at one point in time). Do I get it right, that with the local access I need to create a separate API thing for every AirGradient device I use? So, if I have 3 indoor sensors, I will end up with 3 API things + 3 location things?

And in addition I also experienced the issue from @mcheffe AirGradient local device TVOC channel not working about the tvoc always being NULL. I assume that’s the same problem as described by @rdslw above.
