Add Text-Items / HomeAssistant-Sensor Display #353

Is your feature request related to a problem? Please describe.
It would be nice to have the ability to show sensor-values of HomeAssistant to visualize a status, measurement, alarm or anything else of a device.

Maybe such a status-display coult be an optional screensaver.

Describe the solution you'd like
Read the values from HA and display them in a room as an entity. These entities could be read only to show just a simple status or, if possible, control a defined button or something else: e.g. display a temperature-value and a fingertip on this value switches something or opens (the upcoming?) thermostate / temperature control.

Describe alternatives you've considered
An alternative may be to display on/off-values with a color. Like lights for example: the label on the left and on the right a dot with red, green or other colors.

Additional context
Such an enhancement could bring new possibilites to use a NSPanel as a status display. Especially if one could select this as a screensaver.
