Trane Z-Wave Thermostats

I haven't had any experience using applescripts with Indigo - only python scripts.

I'm not married to Applescript...that's just what I was able to find. If you have something similar in python you'd be willing to share, I would be all ears.

I haven't done anything with voice in python. I'm pretty much a python beginner.

Here is a simple example of a script that speaks weather information. It would require a bit of adapting.

Thanks Dave. That will help immensely. I downloaded your WU plugin and am working through that now. For some reason, I previously thought it required a paid subscription but I see that isn't the case, and have acquired an API key. Working through setting it up now but need to read through more of your documentation. Also trying to figure out how to truncate the spoken decimal point in my Applescript for the Trane thermostat. So much more to learn!!!
Thanks again!

You're most welcome. Happy to try to answer any questions you might have. I'm not up on AppleScript, but using Python, you can do:

>>> zz = int(z)
>>> print(zz)

Finally got around to installing a Trade XL624 (TCONT624) and I'm seeing some behavior that I don't understand. I obtained this one on the secondary market, and I suspect that what I'm seeing is the result of an old installer setting left by the last owner. I had the thermostat professionally installed, but I wasn't home at the time. I don't believe the installer would have set something to cause what I'm seeing, but I don't know that for sure.

Included the thermostat in Indigo no problem.
Indigo didn't report humidity right away (the state humidityInput1 was not in the dict at first), but it showed up after awhile and was then visible in the Indigo UI.
The thermostat was set to heat mode.

This morning, Indigo called for heat and the thermostat display said it was on stage 2 heat.
The Indigo UI said that the thermostat was cooling, and displayed the idle icon.
I suspect it's this bit that's causing the confusion: "Thermostat - Downstairs" is cooling (auxiliary)

My other XL624 doesn't display this message as far as I'm aware. I should note:
Thermostat - Downstairs Firmware: 2.31
Thermostat - Upstairs Firmware: 2.12

What is auxiliary cooling mode?

That looks like a buglet. Back before we had access to the Z-Wave docs/SDK, we had to guess on what some of the thermostat operating state values were and I guessed wrong on this one. Will be fixed in 7.3.1 to have it set the state to heating instead.

Thanks Matt - Let me know if you need a device dict to help decipher what's going on (although it sounds like you've already got it pegged.)

Confirmed fix. Thanks Matt.

For the 824 and higher thermostats, it does look like someone has figured out the API but it does use the Nexia cloud service:
https://www.npmjs.com/package/@cdmnky/nexia-api

With the coming changes to Nest, I've been looking at different thermostats. Most have the built-in bridge so it may or may not be able to be controlled natively from Indigo using Z-Wave. I also think Matt or Jay have stated in the past that Indigo doesn't support going to a different controller. Some of the thermostat models are not cheap and to find they won't work could be a risk not worth taking.

I'd still recommend getting one of the older Z-Wave only (not WiFi) thermostats. The Trane models seem to be pretty reliable. They aren't as sexy as the higher end WiFi models, but for reliable cloudless control straight Z-Wave is the best approach IMO.

+1

After we got rid of our Nests, we've used nothing but Trane Z-Wave units and they have been rock solid.

Anyone out there using the XL1050/XL850/XL824? I understand the XL624 already works with Indigo.

We're switching out our main HVAC unit and the only suitable units (variable speed compressor and air handler, plus zone control) use these thermostats.

Looks like there's a reverse engineered interface for the cloud server that someone developed for Home Assistant. I think I can use that to build an Indigo plugin.

There's been sporadic discussions on the forums, but I don't recall seeing anyone who has successfully integrated it. Last I heard, there wasn't an official API, though the reverse engineered stuff might solve that issue.

Our new zoned Trane system with Nexia controls was installed this week. Too early to tell on the system itself, but I'm not a huge fan of the thermostats, at least compared to the Ecobee. They just look like older tech, IMO. Oh well, can't be helped.

So I've started working on the plugin. I've gotten it to authenticate with the Nexia website and pull down the thermostat data in JSON. So far, so good.

I'd like to see how my data compares to other's who do not have a true zoned system, or have multiple independent systems sharing a Nexia account. If you're using a Trane/Nexia thermostat, have a nexiahome.com account, and would be willing to share your configuration data, I would appreciate it.

Further discussion on the new plugin should be here: viewtopic.php?f=216&t=23021
