I have a Trane ZWave thermostat. Until yesterday, I had it connected to Smartthings, and I was able to set/read values in HomeAssistant via the ST integration.
I picked up the Nortek Zigbee/Zwave stick yesterday and started the process of completely moving off ST. I excluded the Thermostat from ST, and connected it to HASS - it is great. I can control the Thermostat just fine; however values are not updated “back” into HASS.
(I’m using ZWaveJS with the Zwavejs2MQTT frontend. Gateway is disabled, and WS is running)
When I go to the frontend, I can look at the details for the thermostat and click the Refresh button to manually update it. I have tried healing, and re-interviewing the device. Is there a known issue or configuration I need to set with Trane Thermostats to have data automatically refreshed?
To summarize: It connected fine. I control the thermostat. But as the state/temp/humid values change the values are not udpated in HASS unless I manually refresh them.
Maybe there are some device settings, you need to change for sending reports more often.
I do not know this thermostat, but most devices reporting temperature have settings, how much the temperature needs to change for sending a report, and how often reports have to be send, even if values did not change.
Yes, I am aware of that. But it doesn’t even update the current mode. Presumably, switching from “cool” to “idle” would cause an update. It did when ST was my hub, at least
I’m pretty sure SmartThings polls in a time interval by default, at least with the generic z-wave thermostat handler. You didn’t say which Trane you have. Most of them are pretty old, if it’s old enough you probably need to poll the values. Z-Wave JS does not do automatic polling, so you’ll need to do it yourself. You can do it in zwavejs2mqtt (Settings → General → Devices values configuration → New Value, pick value and Enable Poll), or create an automation in HA to occasionally execute the refresh_value service for the entities to update.
It does. You can also setup a DTH or driver to do so and most of the thermostat DTHs ive seen do. That’s why it was likely ‘working’
The XL850 is the ‘newest’ one I know about (and it’s older then the one in my home - the 950, when Trane/AS started doing wifi by default and mine is already over 5 years old…) and AFAIK the 850 is not ZWave Plus.
I suspect you’re correct about this device needing an occasional poll.
