3 way switch from banggood - 433 IC unknown

Hi everyone,

Recently I bought a super cheap 3 way switch from banggood. It does transmit, RFLINK sees the code, but it is unsupported. I opened the device but the 433mhz IC is unknown.

I hope it can be supported in RFLink, since the switch is overall really great.
This is the device: https://www.banggood.com/86-Type-123-Wa ... 34774.html

Here is the debug log, both in jpg format and txt format. I hope it can be added to rflink! :)

Edit: I forgot to mention that this 3 way switch only sents an "On" command (i.e., each individual switch only has one button. Not 2 (On & Off). So one device has in total 3 RF codes, 3x ON).

Code: Select all

10;rfdebug=on;

Hi,

try this https://test.sui.li/oszi/ to "see" data,
they are very similar between 3 commands.
Probably simple to decode ;)
Look for «433 reverse engineering» on google, many people explain how to.

Hi Swil,

Thanks for your reply. The problem is not that I'm unable to decode it myself, the problem is that rflink doesn't support this device (yet)....and since RFLink is not opensource, I can't add it myself to rflink :|

I hope some of the devs can incorporate it in rflink!

Hi,

i think, if you have skill to do it, it’s possible to write your own plug in and try it.
when it work, send it to rflink team.

A source, not official, can be found here : https://github.com/jwdb/rflink.

Swirl,

I appreciate your replies but your suggestions are not an option. Using the old rflink code and implement the switch myself is not viable, since I will lose devices like milight.

Nobody from the dev team who can implement this switch to the current code? Why not opensource the current code..... :roll:
