This works great with a generic humidifier. I have it set up to grow mushrooms in a shower with plastic over the top and shower doors, and it keeps the humidity at a perfect 80%. Easy to use, reliable, and the sensor is as accurate as my calibrated dewpoint meter. It is really easy to see the display and it has held up great in this environment.

I love this controller. I have a regular house hold humidifier in a grow tent and this controls the humidity like a charm! It has two outlets one for humidifier and the other for dehumidifier. I don’t know how well the dehumidifier side would work because turning on and off I feel like would reset the unit if it were digital. With an analog dial on the humidifier this unit works flawlessly with it. Love it so far about 1 month into using it.

1500 Watt mention is misleading. Instruction Manual is updated to show 1200 Watt., 10 Amp.

Easy to program. That is what is most important to me. It is accurate as I have checked it with a dedicated humid meter and it is always within 1 or 2%.

Stopped working after 24 hrs. The dehumidifier that was plugged in consumed 588 watts. Now it doesn't light up at all.

Very nice, but the easiest thing to say it all is that everything that comes from VIVOSUN is an excellent highly recommended product and company. I am on my third extended grow tent and love them.
