What should I get to control my dehumidifier?


I want to have my dehumidifier come on/off automatically at a set humidity… I don’t trust the auto settings on it as it’s old and not very reliable in that sense…

I recently got a Ecobee4 and have a bunch of the Visonic Door/Window sensors but they don’t do humidity…

I was thinking of a Peanut Smart Plug as they are only $18 to control the power to it…

Now I’m wondering what I should get as far as a sensor… If there is something that would make sense to also somehow tie into my Ecobee4 that would be great too…

I’m sure the pros here will know what to do…

Thanks for any replies…

You might check the thread below. I’d just use the humidity sensor in the ecobee. Aeon Multi 6 motion sensors also have a reasonably decent humidity sensor. Then, you can use SmartLighting or WebCoRE to turn the dehumidifier on or off. I have my dehumidifier on a plug using a WebCoRE piston. The thread will have examples and thoughts:

Just another note, I use the Aeotech Smart Switch’s power monitoring feature to send me a notification if the Wattage drops below a certain value. Because the bucket is full, although now that I set that up the gravity drain to my sump pump is working properly… go figure…

Also very important! Make sure whatever switch you buy can handle the amperage! Dehumidifiers are power hogs! Last thing you want to do is melt a switch or start a fire…

FYI “Peanut Plug” (the round one with 2 angled buttons) in ST did not and perhaps still does not report power, though it was advertised to do so.

Also the “ST Outlet” (the rounded-square one by Centralite) reported power at 0.1 increment, very noisy logging for little-improved information.

I think the Zooz Zen15 plug-in is pretty good with ST default Device-Type-Handler. With custom DTH by krlaframboise , this device reporting is deeply configurable.


I have 3 of the ones I linked… I just use them to control on/off and don’t care about the power reporting… I have a Sense which does whole house reporting… Would be nice if it did, but don’t need it, personally.

Thanks for the reply.

I have a bunch of Peanuts and Iris Plugs. I use the Iris Plugs when I need to measure power. I use the Peanuts when I just need to turn something on and off.

Although I have 2 Ecobee Therms, the humidity sensors are not enough for my needs.

I have found great success with the Zooz 4 in 1 multi sensors when dealing with humidity. I had to hard-wire these as the batteries don’t last long enough.

I am also checking out the Xiaomi Humidity and Temp sensors which seem to work just as good thus far. These are a little tricky to pair. I am using these for 4 humidifies that I have in various rooms in the house in conjunction with Peanuts. So far, so good.



Thanks for the reply! That Xioami is nice and cheap! :slight_smile: So there’s no native DTH for it?

You finding the Xioami accurate?

No native but:

As far as accuracy, I have a regular digital calibrated hydrometer that I check the “important sensors” with. The Xiaomi Sensors are actually pretty darn accurate!
