Yes, as you documented, I extrapolated the ON message by using the first bytes of the second message of a Sun trigger. Regarding the ON/OFF stuff, you could make a slight change to your code to also send the ON message every time you call Sun1/Moon1. As of today, if you send the Sun1 command to the ...

Hi, Just tested your code with my Arduino Nano + 868Mhz CC1101 module, and it works perfectly !! IMG_4787.JPG Bellow are my codes acquired with my RTL-SDR dongle (2 messages are sent each time I trigger an action): Zone 1 Moon [00] {590} 55 7f 7b 0e ca aa ca ad d5 55 7e 2b ff c0 42 78 9a aa 9a a9 15 ...

Thx Sixk for this detailed explanation ! Even more clear after reading the full thread :-) Now, time for some dumb questions (maybe a bit out of topic), as I am not a RF expert ! - I took a few minutes to look at the code, checked this tread and ... you never talked about pulse timing (how long 0 ...

@SixK, no problem with your code, I just forked it and tried to push it on one of my arduino Nano, it runs successfully ! Just noticed that it says that the CC1101 initialization is successsfull ... even if there is nothing connected on the SPI interface ;-) But this should be related to the CC1101 ...

Thx guys for the great job on this ;-) Finaly, those Deltia Dore device can now be integrated in our domotic & IOT playground ! FYI, here are the devices I just bought to get this stuff working. It cost me around 25€ (including shipping) : DVB key for intial code acquisitions (SDR compatible) : http: ...

Great Jimmy ! Hum, so I may have missed something in the API, as you seems to confirm that the whole frame is generated (including house code ...), not only the message portion :-) I didn't find the class where the contol bits and house code are generated in the API, but I may have looked badly ...

Thx Jimmy, Based on my initial look, the USB transmitter does not (unfortunately) seems to be a "dumb" 868Mhz encoder/transmitter. It looks like the API only sends the message portion of the frame to the transmitter (and the transmitter then adds all the headers, like Source, Destination, control ...

Thanks Jimmy, I had a fast look to the SDK, and decompiled the JAR. With this in the pocket, it won't be an issue to get the format of the messages that are sent to the USB Key (and quite all message type can be generated by the SDK - ie. Heating Control, On/Off ...). The SDK seems to directly ...

Hi ! Keep the good work ! Were you able to get any improvement since your first post ? This is (also) my first post on this forum, I found this thread by googling around ... I was desperate to see somebody trying to reverse engineer this protocol used in Deltia Dore products (mostly across France ...
