Add Temperature Sensor

[michikrug]

As it was reported multiple times that the current way of providing a temperature sensor using a thermostat device is not working nicely, this PR adds a new TemperatureSensor device type.
(See Temperature Sensor and Google Assistant @ openHAB Community)

With this new way we
a) Do not need the thermostat group item anymore
b) Only get response with the current temperature without the information "Thermostat is off"
c) Can not anymore see the value in the Google Home app, as sensors do not have any UI currently

Same as for thermostats we also can specify useFahrenheit=true if required.

Hello, how can I use this?
I've tried the following, but google home says the thermostat is not setup yet

Group g_LeonsRoom_TSTAT "Leon's Room env" { ga="Thermostat"}
Number Tsense1 "Room temperature [%.1f °C]" {channel="mqtt:topic:502d7cd3:Tsense1", ga="TemperatureSensor"}

Also, is this feature even included in the latest build of OpenHAB or do I have to wait for that?

Hi. Thanks for reaching out.

First of all, all changes in the Google Assistant integration are independent of openHAB itself. Thus, the features mentioned here will not be bound to any specific openHAB release but will be released separately without you having to update anything.

Secondly, the sensor feature is not yet released. You can only try this by hosting your own openHAB cloud instance and assistant action as described in the README.

Furthermore, the usage of the sensor would be without a Thermostate as a standalone item. Unfortunately, there will also be no user interface for the sensor in Google Home.

Thanks a lot for the info!

Do you know where can I subscribe to get the relevant info when all this is implemented?
