Calibrating temperature for new (2014) SmartThings SmartSense Motion Sensor

[topl (Top Lertpanyavit)]

I can only answer the first question: the new motion sensor can only be powered by battery, as the micro USB port has been removed.

You can read more about it in the following thread:

Has everyone seen the next generation SmartThings?

We’ve updated a few devices and they are now available for sale. You’ll find a new (ZigBee-based) SmartSense Moisture, a new SmartSense Motion, and a new SmartSense Open/Closed. All are available in multi-packs. For more on what is changed in each device, check out the blog.

Cheers,
