when I point my browser directly to my purple air on the bottom of the “live” webpage there are a bunch of three letter acronyms, some in green, some not. What do these symbols mean?

NTP LOC UPD PAA TSA TSS 3RD TSB TSS 3RD  
V7.02 2.0+BME280+PMSX003-B+PMSX003-A

I know v7.02 is the newest version number. NTP usually means a time server. LOC probably something to do with location. UPD prob something to do with location. PAA/TSA/TSS probably something to do with pressure and temp for sensor A and B.

thanks.
