homebridge-airvisual-pro's Issues

I have added IQAir visual pro to homebridge,but can’t get any data.

Hi,
In Home App, there was showd humidity 0% and temp 0.0 and Air Quality Unknown and Carbon Dioxide Ready but no data. Why?

Thank u.

AirVisual JSON format issue

I've found that my AirVisual (System Version: KBG60F82 / Software Version: 1.1651) writes its measurements into a JSON object within an array rather than just into a straight JSON object, i.e.:

that.airdata.measurements[0].pm25_AQIUS as opposed to just that.airdata.measurements.pm25_AQIUS

In my case then, the plugin was initially not finding any measurements. A quick search-and-replace did the trick. It's possible that others are experiencing the same problem so it may be worth implementing a more generic fix catering to both formats.

Great plugin – thanks!

smbget fails; workaround available

Using ubuntu 20.04.6 LTS, this smbget command fails (to see if you have the same problem, try it yourself):

smbget -O -U airvisual%<password> smb://<ipaddress>/airvisual/latest_config_measurements.json

It is because samba requires more up-to-date security by default. A workaround is to edit /vi/samba/smb.conf and add

client min protocol=NT1

inside the [global] section.

Note that I"m not really a linux expert; there may be a better way to do this. It took a little time for me to figure this out, so hopefully this note will save someone else some time.

A better fix would be to use a utility that allows the protocol to be set explicitly, or perhaps use the AQI apis (not sure the tradeoffs). However, a temporary fix would be to at least add this hint in the setup instructions.

API

IQAir has official api.
There is no need to do exec smbget or it would be great to do both implementation: if homebridge hardware has internet - do request to api else do exec()
