Bought a Philips Hue button and an emergency button for 9 euros on Amazon.
16 randomised sounds (many fart sounds) from Soundboard in Homey played on my Sonos speakers.
Open the emergency button, undo two screws that takes away the contacts. Tape your button on the bottom of the case. Glue something on the backside of the emergency button that touches the Philips Hue button when pushed. My measurement wasn’t the best. I was off by 3mm so I taped a piece of plastic to the button.
Some sounds turn off the light in the entire house and then turn them on again afterwards and some like the Bad Boys intro makes the lights flash in blue and red
Works like a charm. Everyone should have on of these in their homes!
