Profiles are no longer published per fixed layout. There is no 5-10-5, 4-10-4 or 3-9-3 file any more. There is now one profile per middle segment, written as `X-10-X`, and you tell the plugin how many LEDs are on your sides.

So the rule is: count the middle run only, and download the profile for that number.

Published middles are 0, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 20, 21. A ten LED middle takes `X-10-X`, a sixteen takes `X-16-X`. If your device has no centre run at all, take `X-0-X`.

The plugin then works your sides out for you. Installing the profile reads that device's strip and fills in LED Devices > RPM Telemetry > Configuration > Number of side LEDs (per side), because a strip total and a fixed centre only leave one answer. That is why the slider is usually greyed out, with the sum shown underneath it. To change your sides, install a profile with a different middle.

You enter the number yourself only where it cannot be worked out, such as a device that reports no LED total. Two things people get wrong when they do:

• Count ONE side, not both. A device laid out 6 + 12 + 6 loads `X-12-X` with a side count of 6.
• Split side runs still count as one side. A 9/3/10/3/9 wheel loads `X-10-X` with a side count of 12, because 9 and 3 are both on the same side.

⭐ Every LED device can run its own telemetry profile, up to 16 of them, so take each device's own middle count and load the file that matches it. This used to be impossible, because side LEDs was one setting shared across the whole rig and two telemetry profiles could never both be correct. That is what the Co-Pilot LED profile was for, and why it has been retired. It is still worth giving a second device a different job, such as brake pressure or the fuel gauge, rather than repeating rev lights you can already see.
