Inspire Aruba RF fan - issues with RFPlayer and SDR tools

Configuration
1

I bought a ceiling fan (Inspire Aruba model).
It is controlled by an RF remote.

I would like to integrate it into my home automation system using the RFPlayer stick.

First, I used the PARROT function on the RFPlayer to try to copy the power-on signal of the fan.
At the end of the process, the LED flashes red to indicate an error.
I tried several times but always got the same result.

As a second attempt, I bought the RTL-SDR Blog v4 dongle to analyze what was happening.

With the SDRSharp software, I can see a signal being emitted at 433.92 MHz.
I then used the Universal Radio Hacker software to try to decode something. When I saw nothing, I opened the “Spectrum Analyzer” and only saw noise, no peak at the expected frequency.

I am a bit lost and don’t know how to continue my investigations.
I would really appreciate any help.

Best regards

Yes, I finally found a solution. I tried to explain it here: GitHub - GuillaumeBerland/ArubaPlusInspire

Awesome!!
i will try this in the coming weeks!

as i have two of these our home, i noticed that the same remote will not work for both fans.

do you know if this could be a problem?

This will be problematic. The first 20 bits of the frame represent a unique address for each fan. So we need to find this address. This can be done with an SDR and rtl_433.

rtl_433.exe -f 433920000 -s 250000 -g 20 -R 0 -X "name=MyFan,modulation=OOK_PWM,short=400,long=1200,sync=6800,reset=30000,tolerance=200" -F json
