Help encoding a 433Mhz signal

Hello all,

I’m trying to modify the following https://github.com/athombv/nl.aldi to support the Lidl similar type set (TR-502MSV). From the internet I’ve managed to grab the protocol as follows:

 # this config file was automatically generated
 # using WinLIRC 0.6.5 (LIRC 0.6.1pre3) on Tue Jan 29 15:51:17 2008
 #
 # contributed by Kuhlie
 #
 # brand: Lidl / WH Mandolyn Int'l Ltd.
 # model: TR-502MSV
 # supported devices: RC-402 and RC-402DX
 #
 #
 # Send one of the on-signals multiple times while pressing the 'learn in' button on the device to learn.
 # This is because of the random 'house code'.

       end raw_codes

 end remote

I’m unsure how to code the signal to use in the /apps.json file. Should I try & make it as general as possible to encode one signal or encode six signals?

Thanks,

Leo

I believe I’ve managed to find the correct signal definition:

Working codes for TR-502MSV

All on/off
"sof": [
    627
  ],
  "eof": [],
  "words": [
    [
      1362,
      686
    ],
    [
      683,
      1362
    ]
  ],
  "interval": 10000,
  "sensitivity": 0.5,
  "repetitions": 20,
  "minimalLength": 20,
  "maximalLength": 20
}

Might help others…

Hello Leo838,

How can you use these codes to send signals with a Homey-app? I’ve got a Wave hood with a remote that functions on 433.92 Mhz: 3 fan-speeds, light on/off, completely off. I’d like to control it with my Homey.
The same for my Faber gasfire and some other light-sets that all function on 433,92 Mhz.

Thanks!!

Hello Roger,

Just saw your message, apologies for the delay.

It’s a fairly long/ annoying task trying to work out the signal. I used:

https://htmlpreview.github.io/?https://github.com/harriedegroot/Athom-Homey-RF-Signal-Analyzer/blob/master/index.html

Which seems to work better in a Chrome browser. I found it difficult to isolate the exact signal of the device I was trying to clone. I would search the internet for someone who has possibly done some of the work for you & try to use that as a starting point. Once you have that you can put it into

I hope you have some Nodejs experience as it’s difficult to understand at times the interaction between frontends, backends & all the in between! You can take a look at the modifications & extra comments I added to

& see if it helps but I’m in the dark to a fair bit of this, my background is simpler embedded devices in C.

Best of luck!
