[Sam Wilkinson] lately put in a Dreo CLF513S ceiling fan in his place — it’s low-cost, well-sized, and blows air round as you’d anticipate it to. The one downside is that it solely works with an unsightly cloud-only good residence setup out of the field. By no means thoughts, although, as a result of [Sam] discovered tips on how to hack up a customized resolution.
Hacking efforts started with the included distant management. [Sam] recognized that the distant needed to be RF, because it didn’t want line of sight to work correctly. The FCC ID on the again of the gadget additional indicated this was the case. Armed with that information, it was merely a case of determining the instructions despatched by the distant, constructing one thing to replay them, after which hooking that into [Sam]’s current Dwelling Assistant setup.
The distant ran on 433.92 MHz, a not-uncommon little bit of spectrum for these form of home equipment. An RTL-SDR was thusly enlisted to seize the output, with a spectrogram indicating the distant used easy on-off keying to ship instructions. As soon as instructions have been captured, [Sam] grabbed an ESP32-C6 microcontroller, hooked it as much as a RFM69HCW radio transceiver, and programmed it to replay the fan on/off command. From there, slightly dabbling with MQTT obtained the ESP32 controlling the fan as desired from throughout the Dwelling Assistant ecosystem.
Typically, it’s onerous to seek out good residence gear that truly fits your tastes and budgets.
