Original Multi Temperature Sensor Gives Mediocre Data

[geeji (JJG)]

You might want to give a try at the Fibaro FGK-101, whose US version ships this month, and which uses the DS18B20.
Fibaro has been making Z-Waves devices and controllers in Poland since 2010, and all their product are beautifully designed and carefully crafted.
I posted a custom Handler for the FGK-101 there :

'Fibaro Z-Wave FGK-101 Temperature & Door/Window Sensor' Full Support Handler

The Fibaro FGK-101 Temperature & Door/Window sensor goes on sale in the US this month (908.4 MHz version) : At this time, SmartThings built-in support for Fibaro FGK-101 is fairly basic : just open/closed. But this Z-Wave device offers much more than that : temperature measurement, tampering alarm and a set of configurable options. AFAIK, it is the smallest available Z-Wave temperature sensor (76 x 17 x 19 mm = 3" x 2/3" x 3/5") and a very accurate one : the optional TO92 DS18B20 sensor is +/-0.5°C accurate from –10°C to +85°C (14°F to 185°F) according to the Dallas/Maxim DS18B20 datasheet : http://pdf.datasheetcatalog.com/datasheet/maxim/DS18B20.pdf. Although still a “work in progress”, the Handler below supports periodic and threshold controlled Temperature measurements, anti-Ta…
