Harbor Breeze RF Codes

Sniffing the Codes

Codes were sniffed with an RFToy running ESPHome. I have not been successful in controlling the fan by transmitting a code from ESPHome, but I did have initial success with recording and retransmitting with Pilight. This suggests it's doable with an ESP, but I'm missing something in the protocol.
