    These timers have no concept of understanding if the air is too humid.

    They want a cooldown period so the unit isn’t cycling constantly.

    eg. turning on and off 30 times in an hour because the sensor triggers the moment it see’s 46% when it’s set to 45.

    They want it so that it triggers on pull humidity down to 45%, wait an hour no matter what then trigger the next time it sees 46% or greater, which could be immediately… or in 5 more hours.

    A pure timer wouldn’t get the same effect at all.

    Best answer I can think of off hand would be Home Assistant related. Get a humidity sensor and a z-wave switch/outlet. Use a dumb dehumifier that turns on as long as it has power…

    On humidity sensor change check if above 45%. If it is, turn on power. wait until below 45% again… turn power off then wait 60 minutes. Make sure automation is set to not run concurrently, that way the currently running automation script must complete it’s 60 minutes cooldown before it can run again
