Silentron SilenyaPhone Top - Not working

[StefanoGiu]

Hello, I've tested the receiver with the sensor of the central alarm: Silentron SilenyaPhone Top - Not working

I used:

• MX-RM-5v
• NodeMCU Amica 12F

I tested it with:

• Remote control - Silentron 5423P
• PIR sensors of the Silentron SilenyaPhone Top
• Contact sensors of the Silentron SilenyaPhone Top

I don't receive any of those signals...

If I use another NodeMCU with XY-FST sender, I can send codes, and the receiver can read them properly.

What is wrong? The sensors and the alarm system is working with 433 Mhz... maybe a different modulation?

I also tested it with the remote control that I have for the automatic gate, but I cannot read the code transmitted :(

Hi. It is possible that the Silentron Sensors and your Gate remote is to "Secure" and use a so called rolling code, that is not compatible to this system.

If the system is a bit more expensive it is possible that its a rolling code, if possible try to get a cheap sensor or remote to test.

Thanks for your prompt reply!!! If the alarm uses a rolling code, can I read it with the MX-RM and NodeMCU?

[atc1441]

Rolling code is for the ones who dont unterstand it only garbage so they can not read it.

Please google an explanaition of what rolling code is, it should make it a bit clear

[StefanoGiu]

I will google for it and study, thanks!!

One quick and simple question. Can I read the rolling code with the MX-RM and NodeMCU?

[atc1441]

As said Rolling code is for the ones who dont unterstand it only garbage so they can not read it.

[StefanoGiu]

I've a bit of problems in understanding your sentence... maybe it's me :) "As said Rolling code is for the ones who dont unterstand it only garbage so they can not read it."

Could you elaborate it a bit more?

What you mean who don't understand it? And only garbage?

[atc1441]

So if you google rolong code you will see that it is just a kind of a random set of data, it can not be decoded by devices or software that dont know the decode mechanism so its garbage for them. Its like the white noise on an old tv. And the software that have the algorythm can only do something with it.

[StefanoGiu]

Got it... thanks!!!

Isn't there a low level method that just got the signal and not the coded digital value of it? If so, one can try to write the code to decode it...

[StefanoGiu]

I also read that, even if it's a rolling code, I should be able to read its value with the switch library... and its value changes all the time...

I am not able to read any signal at all from it...

[StefanoGiu]

if (mySwitch.available() --> This never becomes true!

can you post code for esp8266 nodemcu . Thank you.

[StefanoGiu]

I used the simple/advanced receiver demo

[upajeewaruwan]

can use HC-12 module as receiver
