Your product looks interesting but I'm curious why you have a "contact for pricing" for your AirGradient One, are you targeting B2B sales with that device? I'm looking at your build kits which are pretty cool. I'd probably get the "PRO Pre-soldered" kit. Couple questions about them: > PCB has slots for TVOC, pressure or other sensors (sensors not included) Do you sell these sensors separately? or have recommendations on sensors you trust and work with this kit? Your AirGradient One comes with TVOC sensing built in so you definitely have something > 24 months AirGradient data platform (or connect it to your own server, e.g. home assistant) Can I use the device without connecting to a server?
