If you can share with me and other person in that forum more info. about your experiences in that topic... "Gateway as Controller". For me that solution and idea is very interesting because I'll tried prepare gateway with LCD and SD card reader only ...to write information from sensors. Extra controller and other stuff isn't necessary for me. You know @hek it can be solution for small environment only with arduino and nRF cards ... Additionally it seems to me that configuration will be much chipper than full architecture (sensors, gateway and controller) isn't it ?
Because I'm not sure where I can make changes in Gateway Code or library to read directly information from message ... help me please and give me advise how I can start with that ... I feel that it could have a future

Michal
