I've bought a Realtek RTL2832 DBV for my RPI to read 433 mhz data and a transmitter HM-T433. I can successfully receive messages from two 433mhz remotes with the rtl_433 utility, but when I try to send any data I am always getting readings like
[00] {0} 00 : 00000000
I've tried sending the data trough the ninjablock utility, RCSwitch, pilight, custom code and a lot more of other possibilities but all readings from rtl_433 are bits of 0.
Is this normal? Is there something wrong with the transmitter (how can I check that)? Am I not reading the data correctly?
