trane z-wave thermostat on sale at amazon

amazon is selling the trane TZEMT400BB3NX z-wave thermostat for $78.99 (free shipping via amazon prime).

i've heard some positive things about this thermostat in the forum. also it seems to be same hardware (possibly with different plastics?) as the RCS z-wave thermostat.

price-wise, smarthome sells it for $115. homedepot.com and lots of other places are $150. MSRP seems to be $300. so amazon's $79 seems like a pretty decent price.

i've installed a few of the venstar-insteon models and while they seem ok, they are sometimes glitchy and every few months or so seem to take on crazy set points for unknown reasons. for now, i'll leave my insteon units in place, but i'll put these trane units in a few locations where i have old non-communicating thermostats.

any advice for/against? other recommended thermostats?

these would be my first z-wave devices. so for now, the extent of my z-wave "mesh" would be 2-3 devices in widely separated locations in my house, plus i guess the aeotec z-stick interface. should i expect signal propagation problems with a sparse and widely distributed network?

make sure you don't get an old version

Resurrecting an old thread. I picked up a couple of these guys from Amazon last week. They are clearly two different versions. One of them shows up with the model number in the Indigo interface, the other (older software) shows up as Generic Thermostat. Functionality seems the same, but the direct LCD interface seems different on the unit. Is there a way to update these guys, or is it a replacement? I already ordered a replacement from Amazon, mostly because the one with older firmware appeared to be open-box, but out of curiosity, can they be updated?

Thanks.

Define/sync both thermostats, then copy/paste the Event Log results of both into a reply post for me. Presuming it is just another model ID we need to add, then we'll get it added to the next minor release.

Sorry for the delay. I assume you are correct.

This is the one that worked.

Got it. We actually had the latter defined in Indigo as well, but there was a typo in our definition file that prevented that model from being loaded correctly.

This will be fixed in the next version (6.0.8).

I hear you on the glitch. I get that a lot. The team here seem to think it happens when you have multiple ones ( I had 4)
Now one is Z-wave and even though it's unsuported it performs way better than my insteon did / does. The guys here also suggested the Trane's I think. So question? These are good to buy? I am replacing 3 with these, want to make sure

I have 4 of them*) since ~ july and they work fine, no issues

Karl

*) TZEMT400BB32.. the sub-version is important - make sure you don't get the old ones

I just posted version 6.0.8 which fixes the problem that was preventing some Trane thermostats from being recognized. Let me know if it works better now.
