MeacoDry Arete® Two 18L Dehumidifier support

Hi! Recently bought a Dehumidifier from Costco & it connects to my wifi after a clumsy bluetooth bootstrap via their ‎Meaco on the App Store

I emailed the vendor about home assistant and they said:

Our AreteTwo is not compatible with Apple Homekit. However here is link for ‘Matter’ which you can see if it works but no guarantee - Interoperability of Matter Products-TuyaOS-Tuya Developer

Host is up (0.020s latency).
Not shown: 999 closed tcp ports (reset)
PORT     STATE SERVICE
6668/tcp open  irc
MAC Address: FC:3C:D7:6C:71:47 (Tuya Smart)

Nmap done: 1 IP address (1 host up) scanned in 1.18 seconds

I have Tuya HACS on local Home Assistant, but I don’t understand how to configure it.

Any suggestions where to go from here? My goal is to get it triggering on and off via GitHub - BottlecapDave/HomeAssistant-OctopusEnergy: Unofficial Home Assistant integration for interacting with Octopus Energy for cheap electricity in the UK.

We’ve just bought one of these (12L), The site doesnt mention anything tuya or matter related so not sure if a connection to Home Assistant will be possible without contacting the Meaco developers. There doesnt seem to be a developer portal or any sign of thrid party support from what I can find

We received ours yesterday and found out the “meaco” app is just a skinned tuya smart app, so all we needed to do was add it to the tuya smart app and it automatically worked with the official tuya integration

Hello! I have got the Arete Two working with HA.

Another community member mentioned in an offhand post that their dehumidifier app has an almost identical UI to the Tuya Smart app. So I thought I’d check the Meaco app, low and behold. It’s basically the same!

Ipsofacto, you can actually directly input your dehumidifier into the Tuya Smart app and it will run it with all the same functionality as the Meaco app. But the difference being, Tuya has HA support!

While this post is for another dehumidifier, i can tell you this applies to Meaco. Many dehumidifiers seem to use the same service but reskin themselves and lock abilities down (clumsily, you can bypass by just using the original Tuya app!).

Note missing functions:
You cannot control modes directly (night, smart, laundry etc). You will have to create your own automations for this.

Tank full indicator is not available (although I am trying to get this to show up, as clearly it there is a sensor that the app can read).

I will make a better post with instructions on how to set this up later in the week.

Hello, I’ve just bought Meaco Arete and this is great news that it can work with Home Assistant.
I have one (maybe stupid) question: is it possible to have it linked to both apps (Meaco and Tuya) in parallel or you loose connection via Meaco app when connecting with Tuya?
Many thanks for sharing your experience!

Not sure, but IIRC it wasn’t possible with Rohnson+Tuya apps, and I don’t think it will be possible with Meaco+Tuya. With Rohnson, there wasn’t much a reason, as the app was just skinned and trimmed Tuya. Is there any use case for using both Meaco and Tuya apps with a single device?

Hiya, did you get any further with this?

As you say setting the mode (laundry, air purifier, night, etc) and seeing the tank & wet status seem to be problematic.

I managed to get it working using the Tuya HA integration. Haven’t managed with the Local Tuya integration yet mainly because it doesn’t have a humidifier device type. I can happily create switches/sensors/etc and I suppose I could use a generic hygrostat helper.
