Is it possible to send a signal to a relay?

I wanted to trigger a relay from the wled app.
more precisely when a preset in the playlist was executed.
however, if that was not possible, just a command option to send to the relay.

in short: I need to activate a relay within the wled code so that I can use the same board without needing another
(trigger relay from another pin on ESP8266 in the same wled code)

I’m very grateful, I love this project a lot, but I don’t understand much about programming.
(Sorry for the bad English, I’m from Brazil)

Not following, but there is a usermod that supports multiple relays and control via HTTP/MQTT.

thank you very much for the information, i will proceed.

Hello, this would also interest me! i would like to build in WLeD next to a bright Lamp and have the option to chose between a GU10 LED spot or WLEd RGB strip. I am not home in the usermod’s, how do i implement this?

Get a binary with compiled-in usermod.
@srg74 has them in his Github repository.
