docs: frame serial vs radio as complementary routes, add 0x26 capture recipe - #105
Merged
Conversation
… recipe The README's "Hypothesis" bullets read as two competing options. They aren't: the serial port is the only route carrying CYCLE COUNTER and PLANT STATUS, while the radio carries only the 5 panel alarm symbols but needs no wiring. Replace with a comparison table saying which carries what. Also add a concrete recipe for forcing the one alarm type never seen on air (0x26 device_fault): the actuator self-test (FUN_a138/FUN_c9e1) flags any output channel whose readback doesn't clear, so disconnecting one actuator and power-cycling induces it deliberately. Same recipe also captures the first-ever state=1 frame, and the state=0 clear transition on reconnect. Co-Authored-By: Claude <noreply@anthropic.com>

Summary
CYCLE COUNTER/PLANT STATUS, radio is the zero-wiring alarm-only complement.rtl433-decoder.mdfor forcing0x26 device_faulton air (the one alarm type never captured): the actuator self-test (FUN_a138/FUN_c9e1) flags any output channel whose readback doesn't clear, so a controlled open-circuit + power-cycle induces it deliberately instead of waiting for a real failure. Same recipe also nets the first-everstate=1frame and thestate=0clear transition on reconnect.Test plan
