Thermostat displays the temperature wrong

Setup, Configuration and Use Items & Sitemaps
#1

Hello,

I am trying to get a Powerley thermostat to display the temperature properly, I have all other control items working, and integrated with Alexa, but I have one last issue. I have it configured to display temperature in °F, however it is showing the current temperature as 20 °F, but it shows the set points correct. This is how I have the thermostat configured in the items file:

Group Thermostat “Thermostat” {alexa=“Endpoint.Thermostat”}
Number Thermostat_Temp “Temperature [%.0f °F]” (Thermostat) {alexa=“TemperatureSensor.temperature” [scale=“Fahrenheit”]}
Number CoolSetpoint “Cool Setpoint [%.0f °F]” (Thermostat) {alexa=“ThermostatController.upperSetpoint” [scale=“Fahrenheit”]}
Number HeatSetpoint “Heat Setpoint [%.0f °F]” (Thermostat) {alexa=“ThermostatController.lowerSetpoint” [scale=“Fahrenheit”]}
Number EcoHighSetpoint “High Eco Setpoint [%.0f °F]” (Thermostat) {alexa=“ThermostatController.upperSetpoint#eco”}
Number EcoLowSetpoint “Low Eco Setpoint [%.0f °F]” (Thermostat) {alexa=“ThermostatController.lowerSetpoint#eco”}
Number ThermostatMode “Mode [%s]” (Thermostat) {alexa=“ThermostatController.thermostatMode” [OFF=0,HEAT=1,COOL=2,AUTO=3]}
Number ThermostatFan “Fan Mode [%s]” (Thermostat) {alexa=“ModeController.mode” [supportedModes=“0=Auto,1=Auto Circulate,2=On”]}

Does anyone have any idea what I may be doing wrong?

thanks,

The item might be expecting Units of Measurement, read Here

I came back in to check this once I saw your reply, and it was displaying 68F, then I went and opened the items file to see if perhaps I did change something and forgot, and in that course of time, it was back to displaying 20F, and noticed this in the events log:

2020-09-30 11:50:35.173 [vent.ItemStateChangedEvent] - Tstat_temp changed from 68.36 to 20.2

I see other log entries like that too, where it seems to display the correct temp for a short while, then go back to displaying the Celsius temperature.

This is a zwave thing?
Many zwave channels use Units of Measurement, as @opus says.
You should check the channel type and see if you are using an appropriate Item type.

Yes, it is a zwave thermostat.

I added

Group Thermostat “Thermostat”, “Farenheit”

I also removed all the [scale=“Fahrenheit” tags as well, this now has it displaying the temp. correctly, however the thermostat is not discoverable by Alexa anymore. I have been only using OpenHAB for about a week at this point, so perhaps there is a better way to do this, but I have not really found any helpful examples of setting up a zwave thermostat.

Okay, don’t check your zwave channel type and see if you have linked it to an appropriate Item type.

I’m not sure what this is -

Is that something you added to your sitemap? It’s not valid syntax.

#7

Sorry, I’ll stop adding to the noise until I have the proper time to work on this and can figure out out how to check the channel type, I am just trying to get all this working in too short of time, in between other tasks, and this is no way to properly do things.

I added that to the .items file, as I found an example of someone else doing that, and it fixed them up as well. I will work on it more once I have time to figure out how to check the channel type.

The easy way to do this is with PaperUI.
There’ll be a zwave Thing representing your thermostat.
This will have several channels.
We’re getting excited about whether the one you are interested in is of type number or of type number:temperature.
Items come in types as well, it’s fairly obvious you need channel-Item links of matching types.

I begin to suspect you may have Simple Mode active, which will have auto created Items (with tedious names) that probably conflict with anything you try to do by hand.

#9

The channel for the sensor is showing Number:Temperature

I did initially have simple mode on, I have since turned it off, and removed devices I added with it on, and have created all the item linking by hand, and by the looks of it I had things set in my items file correct?

None of the Items you have shown us are of suitable type Number:Temperature.
Using that channel with a plain Number type Item is square pegs and round holes.

#11

Thank, I think I fixed it, showing the correct temperature in all devices, including Alexa:

Group Thermostat “Thermostat” {alexa=“Endpoint.Thermostat”}
Number:Temperature Temperature “Temperature [%.1f °F]” (Thermostat) {alexa=“TemperatureSensor.temperature” [scale=“Fahrenheit”]}
Number:Temperature CoolSetpoint “Cool Setpoint [%.1f °F]” (Thermostat) {alexa=“ThermostatController.upperSetpoint” [scale=“Fahrenheit”]}
Number:Temperature HeatSetpoint “Heat Setpoint [%.1f °F]” (Thermostat) {alexa=“ThermostatController.lowerSetpoint” [scale=“Fahrenheit”]}
Number Mode “Mode [%s]” (Thermostat) {alexa=“ThermostatController.thermostatMode” [OFF=0,HEAT=1,COOL=2,AUTO=3]}
Number ThermostatFan “Fan Mode [%s]” (Thermostat) {alexa=“ModeController.mode” [supportedModes=“0=Auto,1=Auto Circulate,2=On”]}
