DC 12V 1CH RF Wireless Relay Module Remote Control Momentary Switch 433Mhz Transmitter and Receiver for Entrance Control, Car Light 164ft (1relays)

You can control other things. I have the exhaust valves on my two other cars controlled by the homelink buttons but those are valve controllers specific to that device. You can add an rf module, hook that to a 12v relay for something light lights,etc and control by homelink once you sync the remotes. Here are two that appear easier to wire to a relay trigger. https://www.amazon.com/RODOT-Wireless-Transmitter-Receiver-Entrance/dp/B09BCC3RBJ https://www.amazon.com/eMylo-Channel-Wireless-Transmitter-Receiver/dp/B01IEIW2RS Here is a tutorial https://www.instructables.com/Using-HomeLink-With-Unsupported-Garage-Door-Opener/
