The KNX eTR M push button has touch-sensitive buttons, with which functions in the KNX building bus system can be called, such as switch lights and devices, dim, activate drives, send values, scenarios. A white LED is integrated into each touch button, the behaviour of which can be adjusted.
A temperature sensor is integrated into KNX eTR M. An external temperature reading can be received via the bus and processed with its own data to create a total temperature (mixed value).
Communication objects can be connected by AND and OR logic gates.

Functions
KNX eTR M1 functions:
- 1 Touch bus button, can be configured as switch, selector switch, dimmer, blind (position and slats up/stop OR down/stop), shutters (up/down/stop), awning (in/out/stop), window (closed/open/stop), as 8 or 16-bit encoder or for scenario recall/storage
KNX eTR M2 functions:
- 2 Touch bus button, can be configured as switch, selector switch, dimmer, for operating drives, as 8 or 16-bit encoder or for scenario recall/storage
- Area function when touching both push buttons. Can be configured as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
KNX eTR M4 functions:
- 4 Touch bus button, can be configured as switch, selector switch, dimmer, for operating drives, as 8 or 16-bit encoder or for scenario recall/storage
- Area function when touching two or more push buttons. Can be configured as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
Function of all models:
- One LED per touch area. On for object value = 1 / Off for object value = 0, On after pressing button for settable time or always off. Settable, as to whether LED flashes at block object value = 1
- Temperature measurements. Mixed value from own measured value and external values (proportion can be set by percentage)
- 2 AND and 2 OR logic gates each with 4 inputs. 8 logic inputs (in the form of communications objects) can be used as inputs for the logic gates. The output from each gate can be configured optionally as 1-bit or 2 x 8-bit
- Configuration is made using the KNX software ETS 5
