hacking remote control of smoke machine

the beamz s700 smoke machine has a remote control with 2 leds and a push button. but the smoke machine has no dmx, so i cannot remotely make it produce smoke. i was thinking maybe it's possible to hack the remote control. i opened it up and measured that there is 220V AC between the brown and black wire. i thought maybe the best course of action is to have a custom pcb onto which i can solder the 3 wires and i can have remote control. so the pcb should have 2 leds and a processor and a component that electronically performs the job of the push button, so that via wifi i can remotely connect the 2 fields which previously were connected to the push button.

any advice on how to proceed? i don't know anything about making pcbs and there being AC involved feels kind of dangerous so this should be done with care and expertise.

just use an esp32 with a relay i think it should match your needs. Ask your favorite ai for the details

Just buy a cheap DMX relay and add it to your smoke machine. Something like this: https://de.aliexpress.com/item/32330773999.html

so for a module like this, the input is 2 wires AC + 3 wires dmx and based on the dipswitch it then just switches the relay outputs on/off? if so, this is a perfect fit.

actually it seems DC in is required. that is not very nice. are there modules with AC in?

Yes, this is how this works.

A source of DC is required. I don't think you will find a module with an AC adapter. But adding an AC power supply is easy and cheap.

There are also some in a metal box with the 3-pin XLR connectors. They need DC as well. You can probably find some like this with an AC power supply built-in; it will be but more expensive.
