I have failed to find where the min/max/step values for each model is stored in the device payload, my assumption is that the application has them hardcoded according to the model number.

I think it would be better if we can set them in the json config in as a string in the format of min,max,step for my device case it would be 16,28,1 for Heat and 20,30,1.

But I'm not sure if HomeKit supports setting different ranges for each mode.

from homebridge-lg-thinq.

The ranges for my device in ThinQ app is:
Heat from 16c to 28c with 1c increments
Cool from 20c to 30c with 1c increments

I notice also that the range changes when other functions are enabled.

Is there any other data that would be helpful?

from homebridge-lg-thinq.

device data json in debug logging, they have device model json and we can extract min/max from this

This is the device info and below is the file referenced from modelJsonUri:

from homebridge-lg-thinq.

Yes, that seems to be correct.

I wonder if they provide the steps information anywhere in that file as this AC units doesn't support setting temperatures in half degrees even though its sensor supports that.

from homebridge-lg-thinq.

I published new test version v1.8.2-test.3, could you try test it?

from homebridge-lg-thinq.

I'm running 1.8.3, I'm no longer able to set 60f, min is now 64f.

Will this thread address custom min max?

from homebridge-lg-thinq.

Range is updated successfully now.
It still allows setting temperatures in half degrees which is not supported by the device.

from homebridge-lg-thinq.

IDK if this is related... I'm getting an error in the log now when the ac is turned on. I'm also not able to set the Cool temp to 60. minimum is now 64.

@JasonGoldenDDT please check your device data in debug log, I need modelJsonUri

from homebridge-lg-thinq.

Sure, here's what I've got:

I'm running version 1.8.3

from homebridge-lg-thinq.

@JasonGoldenDDT I just released v1.8.4 to fix your issue
