I have been looking for a long time for something similar to use with my own blend of essential oils. I first bought an unknown brand on bol.com that was supposed to work with the Tuya app, but it didn’t work at all. Could not connect it to the app. Overall seemed a bit dodgy with poor English instructions as well. So I returned that one.
I then found that Duux humidifiers make use of the same technology as aroma diffusers, and they also support the use of essential oils. They have a proper integration with Homey (I know from my ventilators). The only downside is that at the moment the smaller humidifier does not (yet?) have smart home integration. So the smallest option at the moment is this one with a 3 liter capacity. I prefer a smaller one so I haven’t bought any myself yet. If anyone knows a good smaller alternative, I would love to know!
