homebridge-airvisual-pro's Issues

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.

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!

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()
