MeacoDry Arete One ESPHOME

Hi all,

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!!

Thanks in advance for any suggestions,

Kind regards,

Hass

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.

So: Are you sure that your Meaco dos NOT have WiFi?

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.
