Everything Presence One/Lite/Pro - CO2 Add-on

Great product

Have nothing to compare against but the integration and responsiveness is great :) good job with the product

My bad for not checking it was compatible with my exact planned use.

I eventual got the Co2 sensor going, however: I fell that you need to elaborate on the instructions. 1, the device needs to be connected to one's computer via ESB and not any old USB power to enable the Firmware update. 2, make it clearer that the BOX below with the selection is where one starts the update from. Perhaps it's me but!!
