For what it’s worth I was able to reach it and was redirected to the https connection no problem. Could be an issue reaching it from within your local network rather than a problem with your server setup directly.

I use a proxy server as the main entrypoint to my multiple servers/vms at home and had to mess around with the DNS settings on my router as the automatically generated entries were different than what anyone else would see from outside.

looking at the schematics of the device I want to monitor more closely, it looks like it’s actually using addressable LEDs with a two-wire protocol, which actually makes things even easier because I can just sample on the provided clock edges. I think these are colloquially DotStar rather than NeoPixel devices. For reference I’m designing some mods for a modern pinball machine and it would be useful to know the state of lights on the playfield since I can’t hook into the code directly.

well, it’s more being able to detect long vs. short pulses, as it’s not the logic level but the pulse width that encodes the bits.

fortunately the RP2040’s programmable IO can run at 40x that 3MHz rate, so with a working program I should be able to differentiate short and long pulses and convert them back to bits. My application shouldn’t need to know exact colors, rather just detecting certain patterns or an on/off threshold state for a specific light in the chain.
