I’ve got some 433mhz transmitters and receivers, I also have a 433mhz remote control (as confirmed by several vendors). I’m basically trying to find out what info the remote sends out with the receiver and then replicate it with the transmitter. Sounded simple enough after all I read about it. I’m not new to the arduino, been messing about with it for quite some time and i’m a software engineer so the code is not a problem.
When i transmit from my 433mhz transmitter and listen on the 433mhz receiver, i get a result on the receiver, so both of these are working. I also have this 433mhz remote control for turning on the lights in the house, so I know the remote works. However, when I press a button on the remote while the receiver is listening, I get no result! Nothing at all! So i know all the hardware works and i know the code works, and they are all (supposed to be) on the same frequency.
One thing I did notice that if i run the transmitter and receiver, that when i press a button on the remote, it stops the signal, so i get no results from the transmitter or the remote. This makes me think that the remote control is having SOME effect on the receiver as it’s jamming the signal, but why can’t it understand what’s coming from my remote?
I’ve tried about 5 different libraries and multiple receivers etc. How do i find the signal the remote is sending, or any other way i can send the same signal as the remote to my light switch?
Any help would be appreciated!
