Aeotec also makes a multisensor that does temp/motion/lux/humidity. It reports battery also. Wakes once an hour to report. It's more expensive than the monoprice one, currently on Amazon for $60:
https://www.amazon.com/Aeotec-Multisensor-temperature-humidity-vibration/dp/B0151Z8ZQY/I wanted a few of these for my crawlspace, attic, and garage. I initially bought a plug-in version (that would also act as a z-wave repeater) but currently it isn't supported by Indigo.
At the moment I only have the one installed in my crawlspace, as my z-wave network isn't robust enough yet for far flung ones.
The one I got was off by 3 degrees. There is a sort-of complicated way to fix this, but it won't work without me waking the device to send it a firmware update, and as I said I installed deep in the crawlspace and I don't feel like going back under there right now. So instead I just convert the temp state to a variable and have Indigo adjust the variable by 3 degrees.
I am intrigued by some of these other solutions though. On another thread, I think it was mentioned that an RXFCOM would also work for this, as there are many compatible thermometers. The reason that is cool is you could also add other weather type devices, like an anemometer, rain gauge, etc. I haven't ventured into RXFCOM, but it looks interesting.
