The knob box, it's infamous! Have you considered going battery powered if you want it to be a bit more mobile? I think in the end, with startup of the layout and position of servos, I came to the conclusion that they shouldn't move - the theory being that they were in the correct position when the layout was turned off, MQTT knows and remembers what position that is (I configured it for persistence across sessions) so therefore everything should just resume from where it was on startup. There was a slight allowance for drift or movement due to power spikes (some of the servos are switched off after moving) so I think I maybe added something to move them a degree or so and back again just in case they'd drifted. Minor point though! Hope you get time to get those storage lines active before the boring work kicks in. Chris.
the MQTT bit works fine for remembering settings, as for battery power I do have a few ESP32 with 18650 battery modules on the back of them. its not too hard to get a 5V supply all round the layout. have to have a think about that. storage loops shouldn't be hard to power up, just need to get on with it as all the servos are in place and the power feeds etc are all done - can drive trains on the two loops, just not (yet) on and off the mainline cheers for watching, and will have a think on batteries
