Showing wrong indoor temperature.

[sonybansi]

The indoor temperature is showing incorrectly (currently 127°C). I have tried using it with and without the outdoor temperature filters, but there is no change.

The filter works only for the outdoor temp sensor (because when AC is running on FAN mode only, it would read 127 and it mess up the graphs. That's why there is an option to filter out this value).

Your log shows that the unit sends value 127 for room temperature. Don't know why. You can modify the source code to ignore this value, but then you would see 0 °C instead of 127 °C which is not better.
