baustromverteiler,
I've just recorded what I believe are dimmer buttons. I have to sets of dimmer buttons (+/-) on the remote, and they have different keycodes. So here are both sets:
1) "+": 92 ; "-": 116
2) "+": 126; "-": 36
It's in the manual that I've found on the net that dimmer should be "paired" with buttons 7 and 9. Regretfully there is nothing on pairing and I don't have dimmer switch, so I can not test it.
winnaing,
It seems, you are right. Not all remote IDs are working. Sorry, I can not find the reason - it is really beyond my understanding. Maybe, I missed something or there is a bug in the code.
So there is a hit or miss approach: try different remote IDs to find ones that work. For example, I found that 7400, 6550, 10550 can be used with Livolo switches.
As to FSK, it is not really a protocol - it is method of modulation used to transmit data over RF. Basically it can be easily demodulated using FSK receiver (the same way as I demodulated Livolo's signal using ASK receiver). And there are two ways to use received data:
1) Try to "copy" code sequence without trying to understand underlying protocol;
2) Try to decode and use original protocol.
First will do if it is about fixed codes. Second is good to deal with fixed and dynamic codes, although to me dynamic codes are really hard to hack.

Sergey.
