Hello,

I am new to rtl_433, liking the tool a lot. Maybe somebody is able to help me with a project I am trying to solve.

My weather station is sending on 433Mhz and supported out of the box. I adapted the 433.conf file for loading only the decoders needed for the project and use json for processing al with a C program.

Now I want to add the status of my verisure alarm which is supported through a config file. I added the decoder into my 433.conf and it is loading without problems. But... the weather station is transmitting on 433 and (if I am right) my verisure sensor uses 866. I did some Google work and it looks like the frequency need to be 869037.22 Khz (hope I am right).

The problem now is, how to config rtl_433 to scan for the weather station and the verisure sensor. I found a hop mode in rtl_433 which hops every 600 seconds. Seems a bit long for me?

So the questions are:

- how to setup rtl_433 to scan data from my verisure

- is 869037.22 Khz the frequency I need and how to tel rtl_433 to use it

- what is the best interval to swap between frequencys so I also can catch my weather station

Thank you very much for any help,

Joe.

there is an option to have it switch between multiple freqs (cf the man
page) but given how affordable the radios are and how many empty usb
ports i had available) i found it easier to just have multiple small
boards doing radio=>ethernet, one per freq.

rasp pi0w seems to be the most affordable usb=>802.11 option these days

nanopi neo from friendlyelec looks most affordable for usb=>802.3.

rtl433 works well on each.

Hi can you help me?

I want to capture my verisure "doorbell" signal to send me a message but I dont get it.

How have you configured rtl_433 to be able to filter the verisure signal

Thanks for all.

869 MHz does not sound right. Start at

-f 868M

and try to catch the a good signal first https://triq.org/rtl_433/ANALYZE.html
