Hi,
Could you please recommend me a good dehumidifier that works well with Home Assistant, and is available in Europe?
Ideally, something that works without any kind of cloud configuration, with a local WiFI or ZigBee API.
Thank you.
Hm, looking at templates.blakadder.com for Tasmota devices I found nothing, but there might be an easier solution.
- Get a power monitoring smart plug
- Calibrate it if needed
- Get the dumbest dehumidifier you can find (it must turn back on when getting reconnected to power after getting disconnected)
- Use the smart plug to control the dehumidifier
- When the plug is on and the power usage is basically near 0 you know the tank is full

Have been looking for something like that too. Not been too successful. Everything I found was either outrageously expensive and / or cloud connected and a data harvesting device.
I ended up buying a dumb one (a Qlima D620). When I find some time, Iâll probably open up the control panel, reverse engineer it and connect it to an Arduino or ESP. The MCU would basically âpushâ the buttons (well, touch them, theyâre capacitive) and read the status LEDs and display. And connect to HA over MQTT.
Not sure if brutally power cycling the thing over a plug is a good idea. Compressors donât like that usually. Even if most devices will have some kind of safety built in, thatâs really only to protect the thing against the occasional power outage, not against controlled power cycling as part of the day to day operation.

I got one of these recently which works great and works with the Tuya app. Havnât got round to adding it to HA yet, but should be possible.
Thanks for the tip for the (hopefully) working device!
However, I have had many unpleasant surprises in the past with devices which âshould be possibleâ to integrate in theory, but in practice they donât work for one way or another. Therefore I would prefer doing my purchase after an actual verification that it really works.
So, would it be possible for you to test it?
Thanks.
Just successfully grabbed the IDs and localKeys for the device, however the localTuya component does not yet support climate devices (it exists as a Pull Request currently), so waiting for that to be completedâŚ
Hello, Alex!
I just wonder if you did something with your D620? I have same model and i also think to install wifi module ESP8266 or ESP32 inside. I didnât disassebmle it yet, it was under warranty so far, thatâs whyâŚ
Just a little heads up.
Most dehumidifiers have a hygrometer built in and can start and stop on its own based on a set humidity.
The one we have in our laundry room is set to 40% i believe and starts and stops on its own.
It even starts the fan only regularly to circulate the air in the room to make sure it gets a good reading.
I donât see a reason to make this device smart, maybe that is just me.

Nah. Wasnât worth the trouble. Its built-in hygrostat works well enough. Right now it sits in my boat and keeps it nice and dry over the wet winter. Thereâs no need for oversmartifying things that work well enough while being dumb 
@Hellis81: correct, my model has automatics built-in, too. But i donât have device constantly on, but only when i do the laundry and if humidity raises above certain level (say 70%).
@HeyImAlex : Aha⌠well, i have mine in a laundry and it keeps humidity within limits to prevent mold. Currently i have a Sonoff Dual R3 to measure itâs power and turn it on/off, while i have a separate ESP module and SHT31 sensor to measure humidity (and temperature) and turn it on when when i do the laundry, and, as said, if itâs very humid. With measured power draw i can see which state is in (under 50W: fan only, above 50W: working, below 10W: water full).
Maybe iâll play with it in the summer. I would like to control power on/off, buttons and âseeâ which state is in (working, fan only, off, water fullâŚ). I know i wonât be able to âseeâ built-in sensorâs value, but thatâs not a priority for me anyway. ESP sensor will stay in a laundry in any case.
70% is a lot.
But if you only do laundry in the room and donât hang wet clothes there then the humidity shouldnât stay high for very long.
We have out room to hang the wet laundry also.
Pardon the messâŚ
Having it up high like this means it blows dry air over the clothes and dries them very fast and I could easily route a drain hose to it.
Itâs completely maintenance free and dries 9 kg of clothes in about 3 hours.
When itâs active, dehumidiferâs internal automation is set to 50%. I agree that 70 is too high.
But, during ânon-workingâ days i have HA automation set to turn dehumidifier on at 70% (just in case, i guessâŚ), when turned on device is still set to 50% and it works a few hours until HA turns it off again. But so far it never turned on this way.
For drying i have a machine with heat pump, so i donât hang anything in the house. The problem is that house is old and not so good insulatedâŚ
Slighlty left field solution, but i bought some âdumbâ dehumidifiers, and added zigbee water level sensors to them.
This lets me know when they need to be emptied, which is the most important thing as they run 24x7 otherwise!
I recently bought wifi enabled dehumidifiers. Two brands. Eeese and Qlima. Both work with the Tuya / Smart life app, which easily connects to Home Assistant. In all it works just fine. And I agree that dumb dehumidifiers do the job too, but if you buy new, why not?
