FAQ
Is there an Alexa command that will read out the temperature?
Yes, you can query Alexa. If your sensor name is ATTIC TEMP HUMIDITY, as it is in my own home, you can say "Alexa, what is the temperature of the attic temp humidity sensor?" And Alexa will return with "The attic temp humidity sensor temperature is 111 degrees."
How often does the sensor check the temperature and humidity for automation?
The sensor updates the app each hour, minimum, but also updates if any of the following occur:
At least 0.9 F degree change over a period longer than 1 minute
At least 3.6 F degree change within 1 minute
At least 5% humidity changes over a period longer than 1 minute
The device reaches a pre-set high or low alert level (set by the user)
Or the SET button on the device has been pressed.
