I recently purchased a MeacoDry Arete One Dehumidifier (not smart) and when it arrived I found that it has a barrel jack connector on it which is used when you connect their proprietary pump for continuous water collection.
From the manual and the small amount of information I can find online it looks like when the “full” light is light on the device power should be sent to this barrel jack to run the pump and empty the water to allow the device to continue operating.
I thought this combined with a voltage divider and an esp would be a perfect chance to detect a full water bin and send a reminder to empty it. I built and programmed the esp, which I have calibrated and tested as working but when I connect this device to the port on the dehumidifier, it reads between 0.4v and 0.7v whilst the machine is running, I left it connect to see if it would jump to somewhere around 12v (what I guess the pump might use) when full but when the device filled up there was no change.
Does anyone have any ideas that I could try to get this working as this combined with my zigbee temp and humidity sensors along with a smart plug could provide all the smart features this device needs at a fraction of the cost and with no cloud!!
I have a “semi-smart” Arete Meaco 12l Dehumidifier. Its Android App can be used in my Guest WiFi. Nevertheless it seems one can implement it via Tuya into HA. I will try this out now.
Regarding your post: At least me I didn’t really understand ow you use your HA. Just to controll that dehumidifier? And 0,4-12V seems way too few for a 230V machine?!
Ok, that worked like a charme. Tuya’s logged into the separated geust wifi whereas HA of course’s operating in the main wifi. In order not have the Meaco as a classic IoT-Device to become a security issue I would always recommend this method.
For my non-smart dehumidifier, I’m using an energy monitoring smart plug to switch it on/off based on room humidity from zigbee sensors. If the power consumption is less than 10W when “on”, HA sends an alert that the tank is full. 95% of the time the alert is correct, 5% of the time my wife has unplugged the device but not the smart plug.
Just wanted to chime in that I’ve successfully added my MeacoCool MC Series 10000 portable AC with heat pump function to HA using Local Tuya. The setup process is quite involved, but I managed using the information available here and here.
I added an on/off switch, a number entity for target temperature (with the bounds set correctly for the upper and lower temperatures you can actually set on the unit) and a sensor for the current temperature. The unit exposes a bunch of other stuff as well, including a mode setting (heat/cool/dehumidify/fan) but since we currently only use it to heat our garden office I didn’t bother adding any more.
Works like a charm and now I can schedule heating with Simple Scheduler
Thanks for the encouragement! I just added mine too - I did have to discover that to put it into pairing mode you have to press and hold down the Timer button!
Being new to hacking HA I would be very grateful of sight of how you added the other controls (especially the power switch) as I’ve never done that.
