The information is intended to allow the occupants to escape safely if required. In the case of a CO alarm no one should enter the premises until qualified engineers have made it safe. The the case of a smoke alarm the occupants are the only ones that can safely decide if it is a false alarm -- if there is a fire no one should enter the premises until the fire has been dealt with by qualified personal. What you are suggesting would mean adding a general purpose computer to essential safety equipment. Anything that adds complications and could affect the main function of the safety equipment would need to be considered very carefully.
I never suggested that unqualified personnel should enter an unsafe environment or people add anything to essential safety equipment. The Leeo just listens for alarms and lets you decide what to do with the information. It does not affect the operation of the safety equipment whatsoever.
In the case of CO2, is it better to have qualified personnel attempt to arrive at 6pm after you get home from work and hear the alarm, or sometime closer to when the leak occurred and you were alerted on your smart phone? (I don't think emergency responders are twiddling their thumbs in the evening or there's light traffic)
In the case of fire, is it better to call the personnel before the retired lady down the street notices the flames and smoke while your at work??
