Difference between 2 temp sensors

[hreed1985 (Heath Reed)]

Does anyone know of an app where I could do the following:

If Temp of NEST > Temp of Netatmo indoor sensor

then turn on NEST Fan

I’m looking for more of a difference between 2 temps and to just turn on the house fan to circulate the air.

Thanks,

There is smartapp supplied with the regular ST mobile app, in the green living section, which does compare two temperatures. But I don’t know if it works with those particular devices.

@hreed1985 I don’t have a NEST to test this out, but it should work. I have an app under review that averages the temperatures on the sensors. You can update it to look at the difference instead of the average. I also have the app on Github.
