Sam Wilkinson Hacks 433.92 MHz Dreo Fan Remote for Home Assistant Integration

Summary
A Dreo CLF513S ceiling fan that shipped with a cloud-only setup was brought into Home Assistant after Sam Wilkinson reverse-engineered its RF remote and replayed its commands locally.
433.92 MHz traffic captured with an RTL-SDR showed the remote used simple on-off keying, giving Wilkinson the signal data needed to reproduce at least the fan’s on/off command.
An ESP32-C6 paired with an RFM69HCW transceiver then transmitted the copied commands, while MQTT linked the controller into Wilkinson’s existing Home Assistant system.
The project shows how inexpensive RF appliances can be folded into local smart-home control without relying on vendor cloud services or line-of-sight remotes.
