23. CO meter activation
This parameter activates reporting the value of CO concentration lev- el to the main Z-Wave controller.
25. CO level reporting hysteresis
This parameter defines a minimum change in CO concentration level which results in sending a new value to the main Z-Wave controller.
26. Threshold of CO meter activation
This parameter defines the CO concentration level, which exceeding will result in sending a new value to the main Z-Wave controller, ac- cording to parameter 25 settings. Adjusting the value allows to get the accurate data in case of danger and helps to save the battery in normal conditions.
Seems like its possible, but nether the code upon stable or beta is using it :
I dont have this device, best if you put a ticket in with Homey for a feature request :
