I have two of the INK-CO2W sensors and after 12 hours being placed next to each other they are reporting different values. One shows 410 for CO2, 68F for temperature, and 38% for humidity. The other shows 649 for CO2, 66F for temperature, and 42% for humidity. I put an Acu-rite monitor next to them and it reports 66F for temperature and 31% for humidity. I sent an email to support, hoping to hear from them soon. In the meantime, has anyone else seen this issue and if so were you able to resolve it?
