Codes were captured via Home Assistant
remote.learn_commandwith a Broadlink RM4 device.Temperatures 16–22°C and 29–30°C were algorithmically derived by reverse-engineering the IR protocol:
(32 - temp)LSB first(temp - 17)LSB firstDerived codes were verified bit-for-bit against all physically learned codes (23–28°C).
