  • Howto: Junkers/Bosch HT-3/EMS with Loxone

    What about

    This howto will describe my solution to control a Junkers/Bosch heater with HT3-bus and the newer EMS-bus.
    This howto will be expanded throughout the time.

    What do you need - Hardware
    • Junkers/Bosch heater with Heatronic 3 or EMS bus (2-wire, this doesn't work for the older 3 wire bus - Heatronic 2
    • FR or CR controller (at least FR 100 and CR100 controllers, I believe the FR10, CR 10 etc, do not work). IPM,ISM,MM, etc modules are also supported.
    • Raspberry PI with Debian Stretch (for this one, I used the new Raspberry PI 3+)
    • Heatronic 3 adapter for raspberry PI ( )
    Raspberry PI

    Attach the adapter to the Raspberry PI
