Environment Monitor · 
wrangle readings from a ZGm053UKA Mini CO₂ Monitor
- receives CO₂ concentration and temperature readings from ZGm053UKA Mini CO₂ Monitor over USB
- sends those readings to a datastore via HTTP API
Only works with the one device I have:
idVendor: 0x04d9 (Holtek Semiconductor, Inc.)
idProduct: 0xa052 (USB-zyTemp)
Config
