Help on RTL_433 - Reading the same code for different buttons (FANCO Fan Remote Control)

Configuration
1

Hi there,

Need a helping hand on how to read the 433 codes from two buttons of the FANCO Fan Remote Control.

I’m using the blue SDR dongle to read the 433 signals from my Fanco fan remote control but the “Power Off” and “Speed 4” buttons are interpreted with the same code with the RTL_433 Add on:

The outcome in RTL_433: the same code “3af542” is interpreted for both buttons so I cant use it in automations

The outcome in MQTT Explorer:

RTL_433b

When I look at the Universal Radio Hacker though, the two buttons have a different code section as detailed below:

Questions:

  1. Am I missing something on the RTL_433 config settings?
  2. How to fix the above issue and have the RTL_433 to read the Power off button and the Speed 4 buttons with different codes?
  3. Is it possible to create a code from “Universal Radio Hacker” and somehow port it into RTL_433?

This is the only post i’ve spotted re Fanco.
I can’t offer much for your RF query, but I’m keen to hear your feedback on the product.

I’m considering Fanco ceiling fans & integrating via Tuya
Cheers

Not much to say about the Fanco Galaxy 5 fan… It does what it is supposed to do and the remote control operates in the 433mhz band :grinning:.

From a home assistant perspective, all automation are sent via Bond Bridge.

If someone still uses the remote control, the RTL captures the signal and updates the fan state on Home Assistant. Awaiting a helping hand on the “fan speed 4” button though.

Cheers

Hi HoneyBadger100,

Did you ever get a workaround for this? I am having the same issue, Speed 4 and Off are the same within RTL-SDR. Broadlink Pro reads them differently but not this.

I’m wondering if there’s a config change so that it captures in more detail maybe.

Hi @Meldge , unfortunately, no technical solution for this one from my side. I have placed a yellow sticker on the “4” button to avoid other people from pressing it instead. :slight_smile:

FYI: I got the same outcome with a “fancier” RTL-SDR v3 device.

Hopefully someone will be able to crack this one.
