Hello, folks.
I have been using the PMS5003 for a while now with ESP8266. I have a Raspberry Pi 3B+ deployed in my basement that has been collecting temperature and humidity readings for me for a couple of years now, so I figured rather than use yet another ESP8266, I’d try to get the PMS5003 working on the Pi. I ordered a PIM477 breakout board and that made things much easier to deal with (THANK YOU!). I also found the Python package pms5003, which had things up and working for me in short order.
I am able to get the values as a tuple, or the ugly “raw_data”, but neither of these show the label for the value.
Tuple:
(0, 0, 0, 0, 0, 0, 16, 4, 0, 0, 0, 0, 4608, 209)
Raw_data:
{‘raw_data’: bytearray(b’\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x08\x00\x02\x00\x00\x00\x00\x00\x00\x00\x00\x12\x00\x00\xc7’), ‘data’: (0, 0, 0, 0, 0, 0, 8, 2, 0, 0, 0, 0, 4608, 199), ‘checksum’: 199}
What I am having difficulty with is accessing the readings as a dictionary. Reading this at github makes it seem like this should be possible, but I am just not seeing how to get this accomplished. I would like to pull this dictionary apart and reassemble it as json so that I can send it to my MQTT broker with the temp and humidity data as I am currently doing.
I did eventually find this guy’s gist at github, and while it does show how to access each of the readings individually, it doesn’t list them as key:value pairs as a dictionary would.
Does anyone know how to get at this “get_all_pm” method? I am running version 0.0.5.

get_all_pm- Returns all PM measurements as a list of dicts that contain the values and tags associated with measurements
Thank you in advance.
