Peter,
?
Just a couple of things I know about relating to some of your questions:
?
- I believe Hornby have implemented Bluetooth control in some of their recent TT scale locomotives, using their HM7000 decoder
- There is a project called 'EX-SensorCAM' that the DCCEX team are working on to use a camera watching a layout to provide the equivalent of block detection.? Have a look here:
- I have personally used 2 x WiFi connected lights to provide scene ambient lighting (Night > Dawn > Morning > Midday > Afternoon > Dusk > Night) for my model railway layout.? Using 2 lamps (1 in the East and the other in the West) provides a shift in the light direction as well as varying the light intensity and colour.? I control the lighting via Jython scripts in JMRI, which sends data out of JMRI to control the lights.
- One of the clubs I'm a member of has a string of W2812 style RGB LED strip for creating lighting effects controlled by an Arduino system.? This could be adjusted to be controlled from a DCC command station
- The DCCEX project has recently included code to allow control of NeoPixel lights directly from the DCCEX command station, using their EXRAIL scripting system:
- I believe some people have used AI to generate Jython code for JMRI, but (not having done this myself) I understand the AI generated code isn't perfect and needs some adjustment.? I have seen people post AI generated code in this group in the past.
So those are just some things I'm aware of that you might be interested in checking out.

Trevor.
