When you say for Outdoor use - what do you mean? What temperature extremes are you looking for? For 3 + years now I have been using multiple HSM100 Sensors   outside. The sensors are not exposed to rain as they live on the window sill with a 4 foot overhang or on the back porch . Know people all over the country utilizing these sensors outdoors. What you have to look at is that extreme cold kills batteries quicker.  8)

I'd like to have a sensor located outside so I can read the true outdoor temperature via Vera.
I can have it mounted under an overhang, but no guarantee it won't get wet during sideways rainstorms.
NY temps can range between 0(F) and 100(F).
I do have a real weather station at my house- I get about 6-8 months out of the two "AA" batts in it's outdoor sensor.

Live in FL so I understand sideways rain  -  have not had any issues to date. Do nothing special with the sensor. Battery life depends on wake-up and temperature extremes. With a wake-up interval of 6 minutes I get 10 to 12 weeks out of the batteries  The HSM100 sensor utilizes 3 AAA batteries.  8)

Thanks,
Maybe you're not the person to ask- but I noticed on the specs page for the HSM100 sensor it notes the temp range of 32° - 104°F (0° - 40°C).
Does this mean when it goes below 32°F the unit will just continue to report 32°F even if it's say 15°F outside?

I have, in the NY Catskills, multiple HSM100's in unheated areas and a HM-TS001 which is outside under the eave (I screwed the mount through the inside of a ziplock bag which is upside down and left open at the bottom) both of these sensors will report well below their rated range,  I believe I did hit an unchanging bottom in a wicked cold snap last year but if my foggy memory serves I think it was in the negatives like maybe -4 F, what I do remember is the temp went to -10 and I believe the sensor did not follow it all the way down. Another observation is they are both quite accurate if temps are stable but dont track changes as fast as my dedicated RC  thermometer. I would imagine accuracy takes something of a hit when they are outside their rated range but I've found them to be quite good.
PS: I'm not sure but I think the HM-TS001 is replaced by the ST814-2, they look exactly the same and though not outdoor rated they are much better sealed than the HSM-100

Thanks pgrover516....

Sounds good then, I can probably eve mount it on the west side of the house to protect it from nor'easters.

Nice thing is at that location it's only about 18-20' from Vera2 with only one outside wall to penetrate- so communication shouldn't be an issue.

Thanks again for the info guys... looks like the HS-TS001 is the way to go!

With it's exposed buttons and LCD display- the Everspring ST814-1 doesn't look like it would last very long in an outdoor environment....

I have the last generation of it working nicely outside for a couple years, read mounting in post above
