Advice for 868Mhz RFLink

#1 Post by manuito » 17 Oct 2018, 22:59

Hello all, and thank you for the great work on RfLink.

For a friend, I have to create a RfLink Gateway for Driving a Delta Dore Thermostat (X2D 868Mhz) but I still don't know if I can start it now because of some questions :
  • Should I start my project right now, and buy the only RfLink compliant tranceiver at all cost (Aurel, hard to find, and > 20€ !!!) ?
  • Or I have missed it and you can already drive any 868 / FSK transceiver with RfLink, like the CC1101 ?
  • Or should I have to wait for the futur new RfLink Release, which may add support for other and more "common" (and cheaper) 868Mhz transceivers ???
The price is very important for this project, I have a very limited budget and I use to buy everything from china directly. The Aurel transceiver is very expensive and hard to find (it's not even available anymore on nodo-shop) so I want to know if I can do something with any other 868 AM transceiver like the CC1101.

For details on this project : the idea is to build a X2D compliant GSM based driver, for a fraction of the price asked by DeltaDore for that. I will publish everything on Github / hackaday once it will be ready, and opensource eveything I can (so sad that RfLink is not opensource :'( … ).
I will not use a raspberry or any domotic box : I will drive the Gateway (made with a nano-mega2560 clone) directly from another MCU, through UART. Or anything else which can do it.

Thank you all for your help !

No.
Just to be sure since I asked a similar question.
Should I/we be able to connect an CC1101 with RFLink instead of an Aurel?

Thank you for the replies. That's sad because it's a very obscure tranceiver for 868Mhz. At least for 433Mhz you have much more supported options :oops:
How did you come to use this one in particular for this frequency ?

I suppose I don't have choice to command it on Nodo store. It's not even available on Mouser or TME :? ...
