As a Meteorologist, I love this! There is one little thing to be aware of with using Purple Air for temperatures, though, as their primary purpose is AQI not temp, all temp data comes with this disclaimer. That said, everything is still at lease directionally accurate.

"Temperature, estimated using a formula temp = 1.0227 * raw_temp_f - 9.3755 developed by Lance Wallace to account for heat generated by the WiFi module and other electronics in a PurpleAir sensor. This will not be accurate for all situations. More information can be found in Lance Wallace's notes."
