![]() ![]() The data seesm NOT to be manchester encoded - it is just a bare bitstream 38.4 kbaud the slides from the nccgroup are misleading.I own some Somfy-devices running on the homecontrol-standard. I managed to record the transmitted frames and started dissecting them. an io roller shutter) once and once only. The emitter (the remote control) issues its encryption key to the receiver (e.g. This key is automatically activated when the installation is first used. io-homecontrol guide_io_en.pdf points out that there is a keyexchange at some point:Įach io-homecontrol ® installation has its own encryption key, which is present in all io products in the home.BitRate 38,4Kbps, AES 128 bit encryption.The following link is currently (07.2016) down, but (if up again) he is already usesing GNU Radio to capture a io-homecontrol signal From_Baseband_to_bitstream.On page 14 of interconnectionconsulting’s-pdf there is a single graphic about the authentication process.They use AES 128bit encryption for some of their communication. ![]() Sadly they use “3 split sub-wavebands” (868.25 MHz, 868.95 MHz and 869.85 MHz) according to the adf7022 product site, which I dont know how to handle with GNU Radio.Some (weak) information about the protocol Re-Implement the protocol with sub 1GHz transmitter chip? (e.g.Use a software defined radio (SDR) and maybe GNU Radio to capture the signal.My question is: Would it be feasible to decode the wireless protocol? Hi, as mentioned in whats-the-status-of-io-homecontrol-velux, there seems to be no one having the io-homecontrol wireless protocol decoded yet. ![]()
