Replace deprecated rgb_order with channel_colors

[TrevorSchirmer]

ESPHome 2026.8.0 replaces rgb_order / is_rgbw / is_wrgb with a single channel_colors key on esp32_rmt_led_strip (esphome#18474).

channel_colors takes each of R, G, B exactly once, optionally with a single W; the value is case-insensitive. No behaviour change — grb and GRB are equivalent, uppercase to match the ESPHome docs.

Walkthrough

The ESPHome configurations update the core version, replace the deprecated LED channel key, and require ESPHome 2026.8.0 for both device variants.

Changes

ESPHome configuration updates

Layer / File(s)	Summary
Core configuration updates Integrations/ESPHome/Core.yaml	The version substitution changes to 26.8.27.1. The LED strip configuration uses channel_colors: GRB instead of rgb_order: grb.
Minimum version requirements Integrations/ESPHome/R_PRO-1_ETH.yaml, Integrations/ESPHome/R_PRO-1_W.yaml	Both device configurations require ESPHome 2026.8.0.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to aa0cb

This localized configuration update replaces a deprecated ESPHome key and raises the minimum supported ESPHome version without introducing an actionable merge-blocking risk; it is merge-ready after normal checks and review.

A rabbit updates the glowing core
GRB channels shine once more
New version gates stand clear
Both device paths now adhere
The LEDs hop bright to the floor

Verified against upstream rather than the description: channel_colors landed in ESPHome 2026.8.0 (esphome#18474), and rgb_order still validates but is marked for removal in 2027.3.0. validate_channel_colors uppercases its input and channel_colors_struct derives the same r/g/b indices, so GRB here is byte-identical to the previous grb. No behaviour change and no change to the compiled binary.

Every esp32_rmt_led_strip block in this repo is covered. I pushed one commit on top bumping min_version to 2026.8.0: devices adopted through the ESPHome dashboard track this repo at HEAD with no pinned ref, so without it an adopter on an older ESPHome would hit Unknown option channel_colors inside a file they never wrote. ESPHome merges remote packages and checks min_version before component schemas load, so the bump surfaces the right error instead.

CI green on stable, beta and dev.
