Simulating RF Remote Button Press via Relay - sebagsm - 04-01-2025
Hi everyone,
I'm using a KC868-A16, and I have an RF remote control that operates at 12V using a 12V battery.
My goal is to use the KC868-A16 to simulate a button press on the RF remote, so I can trigger it from Home Assistant.
I’ve opened the remote and soldered two wires to the button I want to control. I know that:
- The button is normally at 12V
- Pressing the button pulls it to GND
So instead, I want to use one of the mechanical relays on the KC868-A16 (e.g. Relay 1) to physically short the button pins, just like a real button press.
My question is:
- Am I doing this the right way?
- where to connect the 2 wires on the KC868?
- Do I need to do anything else to ensure safety or reliability?

i suggest you chose relay board, NOT mosfet board. such as chose KC868-A16S relay controller. the relay output is dry contact, connect to your remote's button wire is better.

If the OP already has the A16 then it's much easier to get an external relay board than replacing the A16 with an A16S. You can get the relay boards from Aliexpress for a few dollars, just make sure that they're high-triggered not low-triggered since most of them are low-triggered for Arduino use (the linked ones are high-triggered). So what you're doing is converting the wet-contact output to a dry-contact one.
