Does anyone know a way that the touch screen can be used as a digital thermometer?
What are you planning to use as the sensor ? If you use general-purpose temperature sensor with a C-Bus General Input Unit, it can broadcast the data onto C-Bus, and this can be displayed on a Colour C-Touch in a variety of ways. A C-Bus Temperature sensor can have its value read and displayed using a "monitor component" on a Black and White C-Touch or Colour C-Touch.
