Is the ElectriQ DESD9LW the most stupidest smart device ever?

EDIT : If you have one of these devices and are seeing the same issues, please use the contact form and let me know, thanks!

Living in an oldish house with 3foot (almost 1 metre) stone walls, one problem I have is high indoor humidity levels. I have been trying to keep on top of this by monitoring the indoor and outside humidity levels and opening windows to try and reduce the indoor humidity, but being in a wet climate this is almost impossible for about 6 months of the year! Due to the need to reduce humidity mostly occuring in the winter months, I decided to go for the desiccant type as the heat emitted would have the added benefit of increasing the indoor temperature as well. For this reason I purchased a smart dehumidifier, namely the ElectriQ DESD9LW, as I was led to understand that the device could be controlled via the Tuya cloud and app.

Within hours of setting it up I noticed that the device was registering totally different readings for temperature and humidity, than all of my other devices. I basically unpacked the unit, installed the filters and plugged in into the mains socket at the bottom of the stairs. I figured this was the best place to test it given that hot air rises and cooler air would drop from upstairs to be heated up and create a nice circulation of air. I also opened all the doors so that air could move between rooms as well. However, within minutes the unit started to register lower and lower humidity and increased temperature and started to say it was at the low level of humidity (22%) and high temperature (29C), which was impossible! The device also slowed down/stopped extracting water. My other monitors all agreed with it being about 16C with a 77% humidity, so something really strange going on there!

I got in touch with Appliances Direct, and they said the unit was faulty. So I had to pack the entire thing up and send it back to them. They wouldn’t despatch the new unit until the current one was back with them! So almost two weeks later, and DPD delivering it to the wrong place, I finally got a replacement unit. I plugged it in and it does EXACTLY the same thing!

Now don’t get me wrong, the unit does extract some water, but I think there is something wrong with the sensors installed in it. My guess is that the sensors are installed on the exhaust or output air stream when they really should be on the intake side. This issue causes the unit to slow down/stop extracting water and makes it almost useless!

Then there is the smart functionality. The unit doesn’t seem to know the difference from power on or power off. Let me explain, I created a trigger in the app so that when the device reads a humidity above 65%, it turns on, and puts it into maximum dehumidifier mode, then after an hour, turns itself off. The app also pops up a message on my phone to let me know it’s been triggered. But the trigger is often set off two or more times in a row, and the second trigger turns the device off!! So basically the unit doesn’t come on about 80% of the time!! Therefore my original question, is this the stupidest smart device ever?

I have a couple of smart WiFi switches which control my central heating and outdoor security lights and these seem to work fine. The heating comes on when it is cold inside and outside. The outdoor light switches on dusk and off at dawn and I can override it at any time using the app (toggles the power to put the light in constant mode). This feature used to drive me crazy when the electric supply was getting interrupted for a few seconds every day as the light would think is was being put in constantly on mode and the floodlight would be on all day wasting energy for no good reason! The smart switches have a power on default, so by setting this to always off the light stays off until turned on by the smart functionality.

The main reason for posting this on-line is to find out is there anyone out there knows how to hack this device, put some decent open source software on it and hopefully make it properly smart!?!

  1. I’m afraid I don’t know how to hack the device, but just wanted to say that I’m also finding that the sensors on this thing are unreliable. It was giving an implausibly high temp and low humidity while on standby; then it woke up and gave a too-low temp and too-high humidity (compared to common sense and a different sensor). Very disappointing.

    1. Thanks for getting in touch! From talking to the support team they made it feel like it was MY fault for not setting up the device correctly, but gave no instructions on how to do it!! Like talking to a brick wall and made to believe you are the only person to have the issue.

      Another annoying “feature” is that it won’t tell you via the app that the water tank is full! It really is a useless device!
