Libraries for transmitting on 433 MHz with well-known protocol

Projects Programming
1

Hi all,

there are many projects and examples on how to receive or even decode 433 MHz signals.
However, I was not able to find one library or example on how to transmit on 433 MHz with one of the well-known protocols such as Nexus, Hideki, Oregon Scientific etc.
I would like to send with such a protocol and receive with rtl_433 running on Home Assistant (temperature & humidity only).
Unfortunately I am not able to decode or code an own function/library.

So, does anyone know about such a protocol/library for AVR chips (atmega328p, attiny old/new 2-series etc.)

Thanks a lot!
Tobias

I think your question is ill-formed.
If you are receiving on HA (don't know what rtl_433 is) then you must transmit with the same protocol.

3

rtl_433 is like a decoder for hundreds of different protocols, so it is perfectly right

4

If the protocol is well known and well documented. then you can code the same protocol to transmit. So, show the documentation on the protocol in question?

5

Post your attempt to send something with well known protocol, so we can see what might be wrong.

6

Which one?

7

Is RTL_433 hardware or software? I know 433 is the frequency.

8

I suspect the OP has discovered NONE of the protocols are documented.

Hard to tell since he hasn't given us any useful information.

10

why don't you use any LAN or WAN based transmission and send your data directly via your network?
