I have a Vera2 controller and a half dozen zwave devices in my network. All have been working fine. However, whenever I try to send a command to my Trane TZEMT400BB32MAA thermostat, I get a “transmit failed with code: 2” message. Even though I get the error message, I can see the thermostat accepting the command and making the change that I requested (e.g. set point, system on/heat/cool). However, the change is never seen on either the mios website or my iPhone app. Also, the temperature shown does not reflect the actual temperature displayed on the thermostat itself.
All my other devices work fine when I send commands. Any suggestions?
I installed this thermostat yesterday and included it to my network fine using the high power add function with my Vera 3. I was able to send commands for temp change and fan on/off initially but sometime within an hour the thermostat stopped refreshing the indoor temperature in UI5 and would not respond to any commands sent. UI5 will send the command and then waits for the node to reply. After 5 retries then displays “Transmit Failed With Code: 2”.
I tried to reconfigure the node but the node would not respond. Then, after the reconfigure attempt, whenever I sent a command I would get “the node is not configured” error.
I then exluded the thermostat from the network. I also reset the thermostat to stock and waited about ten minutes. I added it back in using the low power add function were I place the Vera 3 right next to the thermostat and then place the thermostat to include mode. I received the exact same results as before. I could communicate fine with the thermostat initially, but sometime within an hour the node seems to “Sleep” or something.
Has anyone seen this issue before or have any options to try? Are there any settings on the thermostat that I am missing that may cause it to sleep or only communicate every so often?
Maybe I just got a bad unit but any help would be appreciated. Thanks
Thanks for your reply. I’m new to zwave and haven’t done anything other than the basic installs of each device. I tried the “Configure node right now” and got the message “Unable to get any information on”. I attached the snapshot of what the thermostat looks like on the dashboard of the website. It shows the unit using 67109 watts. Weird. There are 3 other zwave devices within 10 feet of the thermostat and they work with no problem at all. The Vera controller is about 25-30 feet from them right now.
I tried to exclude the device by hooking up the portable battery to the Vera2 controller and putting it next to the thermostat. However, when I pressed the “Yes” button on the thermostat to exclude it, nothing happened. It’s still on the network. I’d like to try and do a reset on the thermostat but from what I read on this forum, if you don’t exclude it first, I’ll end up with duplicate thermostats on the network. Is there anything I can do before I reset the thermostat to prevent the Vera controller from having 2 thermostat devices on it when I do an include after resetting the thermostat?
Also, when I click on the “Advance” icon on the website and check the firmware tab, I get the following information:
I tried 2 additional things with no luck. I disconnected the power from the thermostat and I did a Zwave repair on the thermostat node “only” by going to the “Repair” tab of the ZWave device. The attached file shows the results of the reset for that node. None of this made any difference. The device still takes the commands and makes the changes on the thermostat device itself. However, the status on the mios website and the iphone app don’t change other than the message now says “Unable to get any information on node” instead of the “transmit failed with code: 2”.
Did you first put Vera in exclusion mode, then answered Yes on the t-stat? (Also, you should be able to remove a device from Vera’s dashboard if it’s actually gone, using the waste bin.)
Yes, I did put Vera2 in “Exclude” mode first by pressing the Zwave button for 3-5 seconds and getting the fast flashing Zwave light.
I was just writing the below message when you replied:
Okay. As a last resort, I just did another “Configure node right now” and this time it worked. Hallelujah!! So, to recap what I did to finally make it work:
Disconnected power from the thermostat itself
Did a ZWave repair on just the thermostat node
Did a “Configure node right now” on the thermostat
Thanks again for the help. I hope this helps someone in the future. It’s a bit frustrating stabbing in the dark until it works.
Took me a while to find my post again, looks like it was moved to here for some reason.
I was able to make my Honeywell thermostat work as I had hoped. I exluded it from the network a third time, and then re-added it so it would be “awake”. It was added with a polling frequency of 60 seconds as before. All I did was changed the polling frequency to 10 seconds. The thermostat has not stopped responding and updates all values very quickly in UI5. Its’s been working fine for days now.
