Controlling INSTA modules with FHEM

To control my Berker hardware with FHEM, I

  • installed a 433 MHz CUL from Busware
  • set the CUL to 433.42 MHz: set CUL_0 freq 433.420 MHz
  • enhanced CUL’s protocol handling: set CUL_1 raw X21
  • activated the CUL for INSTA Funkbus (IFB): set CUL_1 raw Jr, something I have to repeat every time FHEM restarts:
    define ifb_modus notify global:INITIALIZED set CUL_1 raw Jr
  • and analysed the FHEM log while sending telegrams with a remote control

(Thanks, Karsten, Martin and Chris)

 I defined every actor this way:

define Actor dummy
attr Actor webCmd on:off

define ActorOn notify Actor:on set CUL raw Js43…US
define ActorOff notify Actor:off set CUL raw Js43…DS

define ActorUp notify Actor:up set CUL raw Js43…UL

define ActorDown notify Actor:down set CUL raw Js43…DL

With the up and down commands, I thought the brightness takes four steps from off to full.
