Trane TZEMT400AB32MAA Thermostat Zwave questions/issues

Update.

After 6 days running just fine on my secondary Vera, I decided to move both thermostats over to my primary Vera. I dis-associated both of the thermostats, and associated them to my primary. For about 2 days they worked fine.

This morning, my upstairs thermostat (closest to Vera) was no longer responsive to Zwave commands. Currently the downstairs thermostat still works. Sometime between 11:00PM last night when I last ran a manual command and this morning, the thermostat failed.

My guess at this point is that either the Trane’s are not happy with being part of a network with other devices and acting as a routing node, or something with a plugin or another device on my primary Vera is causing the issues.

Since the Trane thermostats are my only current problem with my Zwave network . I am leaning towards something with the firmware on them with the rest of the network.

I’m doing a research project on home automation systems and am looking to talk with a few “power-users”, which many of you seem to be. Will you please shoot me an email if you’d be willing to have a brief discussion about your systems and your perspective on the features or functions you’d like to see in home automation in the future? Thanks in advance for your replies!

[quote=“niharmehta, post:5, topic:176171”]Is anyone else having issues with their Trane thermostats becoming unresponsive to Vera ? I have two installed and both of them generally drop off the Zwave network after a day or two. I pull the Trane panel to disconnect power and plug it back in and Vera is able to again connect.
I have excluded/re-included the thermostats and it has not fixed the problem. I do not have any other 900Mhz devices in the home that could be causing interference and all my other Aeon/Evolve/GE/Everspring/Schlage devices are working fine (about 18 other devices).[/quote]

Mine has learned to reboot after “Trane Wreck” I guess it is the onboard watchdog that reboot the MCU… that part works real good!

My Trane is in a mesh with about 20 other devices and in about 3 years hasn’t given me a lick of trouble with my UI5 Vera3. For about 2.5 of those years I know several devices routed through it without any ill effects. A few months back if performed the external antenna mod on Vera and now no other devices route via the Trane. The Trane now directly talks to Vera and is as stable as before.

Considering it works on one of your Vera’s and not the other I’m thinking you are right in your assumption that possibly a device or a plug-in may be the cause of your Trane wrecks.

To determine if devices route via your Trane, get it’s ID and in the Advanced tab of your other devices look for the AutoRoute variable.
It’s contents look something like eg 0-5,9-15,15-17,10-17. Where in the x-n format, the x is the ID of teh device it routes to (0 is vera) and the n is the strength. In the above example, the default route is to device 0 with alternates via devices 9, 15 and 10. The lower the value for n, the better.

Update: I snapped a pic of my Thermostat info and attached it for reference.

I have 7 Tranes between 2 houses (one with 4 zones and one with 2 house units and a garage unit) I haven’t had any trouble in the last 1.5 years.

I am pretty sure some other devices in the mesh are routing through it…
Trane AutoRoute is: 0-5,3-15,4-15,6-17

Are you thinking “Vera style zWave Routing” is the fastest way to confuse/crash this Trane and the concensus is to do an “Antenna mod” to disable Routing through Trane?

It would seem it is FW realated as I have the same FW:02.02.15 and the same goofy behavior after a while.

Are other TZEMT400AB32MAA 3 StageHeat + 2 StageCool as well?? 'cause I don’t think this polling log is looking so good:

02      11/17/14 14:10:49.783   ZZZ-POLLING H1,C1,H2,C2,/1/1 <0x2c381680>

I am betting for a mismatched setting…

That means your Trane routes directly to your Vera (unit 0) with strength 5. Which is what mine is. That’s actually a good sign
You’ll have to check your other devices to see if the first entry in their AutoRoutes variable is the Trane’s ID. Which indiicates it routes via the Trane.

Thank you so much to help and shine some light on Vera routing. Lucky me, my Vera is located in a central position and since the stat is also central, no other device show the Trane nodeID listed as a primary destination for routing. So it is not doing mesh relay, my basic network only has zWave 8 devices.

There is really something odd here to crash that Trane almost reliably ::slight_smile: I am going to try turning off: “Limit neighbors to Z-Wave discovery” to let full-power devices do their own mesh chat to see if it is gets better/worse…
