Combining multipe temperature sensors to get an average

riaan · September 23, 2019, 12:41pm

I have recently moved from Smartthings to Hubitat, I really enjoy the fact that everything just works without babysitting the system.
Is it possible to set a rule to get a average temperature from two or more temperature sensors and have it trigger a action based on the average of the multiple sensors?

You could try using this example app from the Hubitat Public GitHub repository. It will create a child device that holds the average temperature of the devices you select for averaging. This child device can then be used like any other temperature device in any automations you'd like.
