Bug report: temperature_target channel is empty for dishwashers

[BjoernLange]

Split from original report by @sirupflex in #5.

Expected Behavior

When I start a program on my dishwasher, I expect to see information regarding the program temperature.

Actual Behavior

When I start a program on my dishwasher, I do not get any data on the temperature_target channels.

Environment

Binding version: v1.0.0-beta.1 openHAB version: 2.5.6 Running on: docker (QNAP Container Station) Involved Miele devices: Dishwasher G7315

Steps to Reproduce

• Turn on the dishwasher, start a program (e.g. "Auto", in my case)
• Check the data for the channels elapsed_time and temperature_target (no data visible)

Possible Solution

Send the value from the cloud to the channel in the ThingHandler.

After further analysis I figured out that the value of the channel is actually set by the binding, but the cloud is not delivering any value (see @sirupflex's post in #5 for the raw json):

"targetTemperature": [
    {
        "value_raw": -32768,   # means: not present
        "value_localized": null,
        "unit":"Celsius"
    }, {
        "value_raw": -32768,
        "value_localized": null,
        "unit": "Celsius"
    }, {
        "value_raw": -32768,
        "value_localized": null,
        "unit": "Celsius"
    }]

@sirupflex: Please check whether the channel is populated prior to starting the dishwasher, i.e. when the program was selected but the dishwasher not actually started.

[BjoernLange]

We had a meeting with Miele and they clarified that dishwashers do not support the target temperature. Sorry for the inconvenience. Thus we are going to remove the temperature_target channel from dishwasher devices.

Thanks for the info @BjoernLange
