This aims to create a plugin for collectd that can read data from multiple SEM6000 devices.

Current progress:

  • Status monitoring works
  • Multiple devices can be read out
  • README updated with some documentation

Not working very well yet:

  • If a configured socket is unreachable, samples are lost for all devices because all devices are queried sequentially and the connect timeout is about 30 seconds ➡️ maybe use one thread per device?

Just minor nitpicks, definitely happy to have this PR :)
What is your opinion of using the mac to submit values?

did you want to indicate root rights for these commands (because of the preceding #)? If not, I'd prefer $ as shell indicator :)

Yes, the # should indicate required root access.

maybe just import the exception here? I don't know if it makes any performance difference but at least it would be less confusing why bluepy is needed in here.

Sounds reasonable. I'll do that!

I'd prefer to use the BT mac instead of a string as plugin name here. There's a good chance we can read the name of the socket over BT and expose it later with this plugin which would allow a mapping even if the name changes.

Are you sure that the name is actually stored on the socket? My feeling is that that’s only a mapping in the app.

I prefer to have a string in the plugin name, because it indicates the purpose of the measurements (which can change as devices are reused). If you don't like it, just copy the address into SocketName 😉 in the collectd config.

I hereby declare this ready for an initial integration, as I don't have a great solution for the reconnect duration right now.
