Z-Wave JS - MH9-CO2 - Temperature Reporting Threshold - Only allows Integer

[damige]

Describe the issue you are experiencing

When adjusting Z-Wave JS - MH9-CO2 - Temperature Reporting Threshold, i am only able to set the value of 0 or 1, but not 0.5 or 0.1.
The example shows 0.5 as a possible value, but when i apply this error appears: "'An error occurred.expected int for dictionary value @ data['value']. Got 0.5"

A temperature sensor with a resolution of full degrees celcius is not ideal.

The text to the right of the input box in the configuration panel isn't an example. It's the unit. So the value you enter should represent the desired amount in the shown unit.

In this case the unit is 0.5 degrees Celsius. So if you want to change to eg 0.5 degrees Celsius, you'd enter 1. If you want to change to 2.5 degrees Celsius you'd enter 5.

[damige]

Thanks for the clarification.
Would it be possible to have the unit changed to units of 0.1? This was the case when i used openhab. and as i use this sensor as input for a thermostat, the added resolution is required.

[MartinHjelmare]

The unit comes from the driver configuration of the device.

If you have proof that the driver configuration of the device is incorrect, ie not matching the manufacturer specifications for the device, you can submit an issue to the driver project issue tracker or even better, a pull request where you update the device configuration to the correct values.

Here's the configuration of the device in question:
