I picked up a PEQ - 3-Series Motion Sensor at Best Buy today.
Linked right up and I now have a motion sensor that turns on my lights.
It can read the temp also (great added bonus)
However, looks like the temp is not updating sometimes unless I click refresh.
I am using Pollster to update my temp from my Nest, but I cannot seem to get the PEQ to show in Pollster to add it.
