 The ZB40 can select one of three or all three rollos and send commands UP, DOWN, STOP. Simplest minimum implementation would require at least 4 bits. So I could hope that one-byte bruteforcing might still yield results. Two byte bruteforcing while also guessing the bps would be impossible in the 60s pairing mode window of the GW60. Unfortunately: NO LUCK.

+Yes, at this point I could just a well have soldered something on the PCB and simulated button presses. But I was curious now, so I grudgingly ordered a overpriced ZB40 with even more prohibitive 9,90 shipping costs from Germany.

 Next step: Listening in on the ZB40 talking to the GW60 using my OpenBench Logic Analyzer.

+Testing the included RF Remote as well as other 433MHz remotes, it would seem the ZB40 receiver just down-modulates the signal into the baseband and pipes the raw signal to the gw60. The actual signal sent by the remote look quite strange though. It's pulse-width modulation for sure.
+Seems to me that the receive (not the remote) could easy be replaced by the contents of this [[http://www.pollin.de/shop/dt/MzIyODcyOTk-/Computer_und_Zubehoer/Hardware/Maeuse_Unterlagen_Joystick/PC_Funkfernbedienung_mit_USB_Empfaenger_X10.html|Remote's USB-Stick]]
+==== Update ====
+Finally resumed the project with a different approach.
+Bought a second ZB35 remote and soldered the contacts to a ESP8266.
