Newer Airvisual Pro models cannot use the binding because the manufacturer changed the JSON format in a non-backward-compatible way.
See this discussion: https://github.com/openhab/openhab2-addons/issues/4593
We need users that are currently operating the binding with an older device.
We need to know if it is possible to update older devices to the new firmware.
If so, we can simply change the JSON parsing in the binding and tell users to update their devices to remain compatible with the binding.
If not, we need to fork the binding and create an “Airvisual Pro” binding for the newer devices and leave the “Airvisual Node” binding intact for the older devices.
