As far as I know SPI pins MOSI, MISO, SCK may be shared, just CS must be independent for each device (we need 3 CS - display, touch screen and radio ) so we will use just 6 data pins.
Of course further testing is needed (my hw not arrived yet so I cannot do it now).
On the other hand, radio may be omitted as the scene controller may be attached over WiFi. Moreover, running esp8266 + TFT display on batteries is not too practical.
Thus, radio is no needed unless we want to use scene controller as a gateway.
