Title: Schlage Link Trane thermostat
Post by: jamenlang on February 13, 2015, 03:02:12 pm

I have a trane thermostat that previously worked just fine with almond plus. i could adjust the temperature and it would update. i was able to change it to cooling mode or auto and it would update. I updated to R070 and now i'm not able to adjust the temperature or change the mode.

The manual for this device is here

This is similar to the TZ43 whose manual is here

I've let the software team know, not sure what has changed, but that's clearly a mistake on our side.

I checked out /hadata/apps/hadata-4c09/zwcfg_home.xml on the almond and found that the thermostat was listed, but the manufacturer was missing.

 <Manufacturer id="" name="">
                        <Product type="" id="" name="" />
                </Manufacturer>

Then I looked at the command classes it was using to see if i could find why i could set cooling but not heat.

<CommandClass id="67" name="COMMAND_CLASS_THERMOSTAT_SETPOINT" version="1" request_flags="2" base="1">
                                <Instance index="1" />
                                <Value type="decimal" genre="user" instance="1" index="2" label="Cooling 1" units="F" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="0" ma......
                                <Value type="decimal" genre="user" instance="1" index="3" label="Unused 3" units="C" read_only="false" write_only="false" verify_changes="false" poll_intensity="0" min="0" max......
                        </CommandClass>

Cooling 1 and unused 3. Got it.


I reverted to 69cb, factory reset, unlinked, relinked, verified i could set the mode to heat/cool/auto and set both heat and cool point. After verifying everything worked correctly.

 <Manufacturer id="008b" name="Trane">
                        <Product type="5452" id="5431" name="Model TZEMT400AB32MAA" />
                </Manufacturer>

and the command class is very simple.

<CommandClass id="67" name="COMMAND_CLASS_THERMOSTAT_SETPOINT" version="1" request_flags="6" base="0">
                                <Instance index="1" />
                        </CommandClass>

I removed and re added the thermostat a few more times, i finally got it to show up again with null values on the android app which is somehow connected to crashes and force closes. i rebooted the router, tried it again, and values started populating like they should, so as long as nothing breaks i have a working setup.
