How do I modify a 12V 433MHz wireless remote control switch relay receiver and transmitter? Someone in the area (neighbor) is using the same frequency.
I have a similar wireless relay and I rigged it up, and i have noticed I have another device nearby that when I use its remote it triggers this wireless receiver. Do you know if there is anything I can do to stop that from happening.
can you use this on cars , ive just one remote on my car and i need another one , if possible can you show how to do it . thank you ! great educational vids btw
i still do not understand how to wire this for what i am trying to do, i do not want to use the same power supply for the thing that i am trying to control as i am going to be using for the power to the board itself ,so of those 3 relay terminals NC, NO and COM, when i hit the button on the remote do i get continuity between any 2 of those terminals?if so which ones, NO and COM or NC and COM right? i just want to be able to wire the 2 power terminals of this RC board to the positive and negative terminals of a battery or transformer to power the RC board then connect 2 wires from the circuit i am trying to control to those terminals and use it in place of a physical switch, the circuit i am trying to control has it's own power and it is not 12v it is a different lower voltage so can i switch something with this without having to connect any of those 3 terminals bridged with the power supply if the circuit i am trying to control has it's won power supply?
yes thanks i figured it out my next question is is there a way to alter the remote FQ so that i can buy more relays without having to buy more remotes ?so i can get different FQ's to control more relays i had a 433mhz universal garage door remote with dip switches in it but the relays won't learn from it the relays won't learn from a bunch of other 433mhz remotes i have either, i thought the 1st relay was broken then i ordered another one and a remote and got it working finally guess it will only learn 433mhz remotes with certain chip sets one idea i had was building an RF TX/RX for the PC , i saw plans for one using a cheap $2 USB soundcard and a super hetrodyne TX/RX set ,read the code from my relay remote with it and alter it a little with the software(forgot what it is called and never used it before but i assume it would be possible) then TX it back after altering it a little or is there a remote that has a way you can change FQ so you can get more than 4 different FQ to control more than 4 different relays, the reason i want to do this is because i do not plan on using the relay remotes because i have a broadlink RM pro, it's a wifi universal remote hub you control with a cell phone so i would use the universal remote hub and my phone and the app instead (hub does IR and 433mhz RF)
To make it momentary I believe you have to either use a different relay in the controller/reprogram it but I don't know how to do that with this specific unit
Joel Chaffen yes, you just splice the output wire of this controller to the accessory wire on the switch, then you can use either the switch or the wireless controller
The ground wire just goes to any ground anywhere in the vehicle, like a bolt or screw in the body/frame or just wire it to the negative battery terminal
