Great idea. I use mine with a 12v power source (all around the house) with 12v-3v step down converters inside each of my airwicks. I haven't actually managed to figure out how to create an 'instant' button push (now, that's on my list :D), I simply power on, wait 30 secs, then power off again on a schedule.
The units have a default 15 second (?) delay after power-on to do a test spray.
I use these via nodemcu's to control x amount of blasts per hour, during certain hours only, and a different schedule if the house alarm is set/unset.
