I hope google will make the temperature and humidity available to these
routines. If google can display them, then there should not be any
technical issue in passing the values to the routines.
In Google Home App, it does display the temperature and the humidity
reported by this Smart Life sensor. I just don't see a way to read
temperature using automation.
I don't see a way to read the temperature from a temperature sensor. In
my case, it's a Smart Life temperature & humidity sensor. I think being
able to determine the room temperature is very important for automation.
