Thanks for the tip off.

I've updated the code to shift right by 3 places and so go back to a 5 bit number.

That's a neat way of limiting the power usage.

I looked at the picture again, it does show a three wire set up.

The actual string I have is three wires. Data and + - it’s likely they have been swapped out for cheaper lesds now, or the picture is wrong.

Good idea! I’ll get the multimeter out.

I can just swap the micro controller with something like an ESP8266 and run WLED.

Oooh! Good spot. I will check other commands and see if that length idea works out. I think it could.

I was trying to automate my BLE connected Christmas lights but instead I created e-waste. Now you can too!

I haven't added any fault tolerance. Should be fairly easy to detect if a route is unavailable and re-write the routing table. And yes, I expect the Pi is still a bottleneck.
