ri-receive-test.yaml

# Onkyo RI receive test rig
#
# Bench validation for the `onkyori` dumper and the `on_onkyori:` trigger.
# Standalone: there is no `api:` block and nothing here talks to Home
# Assistant. Companion to ri-transmit-test.yaml, which transmits.
#
#   esphome run ri-receive-test.yaml
#
# Wiring: RI is 5V TTL on a 3.5mm mono jack, tip is data and sleeve is ground.
# ESP32 pins are NOT 5V tolerant, so bring the tip down through a 10k/20k
# divider to ground (5V * 20k/30k = 3.33V). Use a divider, not a BSS138 board,
# which is never high-impedance and would hold a bus it only listens to.
#
# Measure tip to sleeve before wiring, amp on and nothing else plugged in. ~0V
# is the expected idle. ~5V means pulses are active-low: set `inverted: true`.
#
# Read `dump: raw` before `dump: onkyori`, or a silent decoder cannot be told
# from wrong polarity, bad wiring, or an amp that never transmitted.
#
# Not every button emits. The A-9050 sends power (0x0EA off, 0x0EF on ~5 s
# after the press), input select for RI-bound inputs, a dimmer counter, and the
# remote's Dock/Tuner section. Volume, mute, tone and the CD section send
# nothing, which is the usual reason a receive test looks broken.
