Meh, don't need all that home app stuff... And, usually only one runs at a time. Should be obvious which needs to be turned on..
Could potentially have slightly more control with the home app, rh probe and smart outlet. humidifier set to conintuous and powers on based on probe reading of your choice and powers off when you choose too... not limited to how the unit works in that regard. This could be dangerous with the wrong dehumidifier, though. There are safety features for the compressor - as long as the defrost mode remains on even if power is turned off or on would be important. With some units, this may reset after a power cycle and you risk damaging the compressor if it inadvertently skips a necessary defrost cycle.
