Hi all! Long time reader, first time poster … 
I have the Dirigera hub for Zigbee control, connected to HA via Matter integration …
Unlike what the previous posts seem to indicate, I get single decimal place accuracy on temp and humidity… i also get PM2.5, and an Air Quality indicator.
Anyone know if “Air Quality” is some sum of all the sensors, or is it a possible representation of of the VOC ?
On my graphs, I seem to have a very smooth update every 5 minutes, I don’t know if that’s just the resolution of the graphs, or if it updates more regularly than that or not.
I do have a Zigbee/Z-Wave dongle, but i’ve got all the rest of the Zigbee stuff attached to Dirigera so Alexa can see it… this seems much less useful to connect to Alexa, so maybe i’ll just hook it up to that dongle as a second zigbee network to get the remaining features…
now to figure out what settings i need for automations to clear the air
