Open source Fanˣ RF Dongle

What’s all this about?

In the summertime on hot days the ventilation can run on higher speeds when everybody is away from home in the morning, to refresh the indoor air via an automated way. Or, change the FAN speed directly by your smart device.

“HACKADAY PRIZE 2022: HOUSE VENTILATION REVERSE-ENGINEERED AND AUTOMATED”

June 1, 2022: [Marcel] thought – what if he had more control over his house ventilation system? You could add some nifty features, such as automatically ventilating your house in the mornings when everyone’s away, only creating noise when nobody’s around to hear it. Sadly, most ventilation systems are not automation-friendly at all – he was lucky, however, as his system came with a wireless remote. [Marcel] reverse-engineered this remote, created a USB dongle speaking the same protocol, and tied it into his Home Assistant setup!
