433mhz sending protocol wheaterstation

[pietervp]

Is it possible to send data over 433mhz to an existing wheaterstation?

I want "to clone" the existing remote sensor. I find some protocol Teknihall GT-WT-02 — pilight 8.1.5 documentation

So I want to send something like this over 433mhz.
The protocol sends 76 pulses like:

532 2128 532 4256 532 4256 532 2128 532 4256 532 4256 532 2128 532 2128 532 2128 532 2128 532 2128 532 2128 532 2128 532 2128 532 2128 532 2128 532 4256 532 2128 532 4256 532 4256 532 4256 532 4256 532 2128 532 2128 532 2128 532 4256 532 4256 532 4256 532 2128 532 2128 532 2128 532 4256 532 4256 532 2128 532 2128 532 2128 532 2128 532 9044

How do i send this signal with a transmitter and how do I check of it is receiving on the serial plotter). Basic sending en receiving like some words I managed.

Thanks,

delayMicroseconds() will work for the timing.

To send a 532 microsecond high pulse I would use direct port access on an Arduino Uno, something like this:

PORTD |= (1<<2);  //set PORTD, pin 2 high
delayMicroseconds(532);
PORTD &= ~(1<<2); //set PORTD, pin 2 low
