A few months ago I watched The Stock Pot's video on hiding sensors in plain sight around the house. His project was for real plants and involved 3D printing, waterproofing and other such things. I'm lazy, so I wanted a setup like his, but with no effort.
While at Ikea, I found a VÅRDTRÄD plant pot. It's got an opaque top but a removeable transparent bottom with a channel in the back where you would normally pour water. The channel is big enough to fit a GLEDOPTO LED strip and controller and there's two holes in the bottom where you can feed the LED strip through. Plug in the strip, throw a fake plant in the top, add to Home Assistant, and you've got an RGB status light that you can place anywhere in the home and get notified when things go wrong.
It's not perfect (I just shoved a short length of the strip in there, so there's dark spots that could be fixed by making a proper circle), but it's a great way to be notified of stuff around the house in a way that can be controlled by Home Assistant.
You could also place a mmWave presence and / or temperature / humidity sensor inside, as it's just a plastic pot with some decent airflow, providing your fake plant doesn't cover up too much.
