Yeah, it drains into a little tray underneath. I'm trying to figure out a better solution for that because we can't see how much water is in the tray, so if too much has drained out, it starts overflowing onto the table with no warning.

Also I get the sense that I shouldn't just be leaving standing water in the tray forever, but it's also pretty difficult to remove the tray and empty it.

Put some pebbles on top of the tray to raise the pot off of it, so it's not sitting in the standing water.

Oh that's a good idea. Thanks!

I usually throw a base of pebbles / marbles into the bottom of any pot before I put the dirt in, which also aids in draining.

Why not connect your tray, back into the Watter reservoir?

This way, it cannot get to Wet, and you could just Pump that Pot full with watter, any excess watter, will just drain through the Soil back into the reservoir :)

Dirty water in the pump is bad.

Put another sensor in your tray wired up to your UI, so as soon as the sensor goes from 0% to 100% for moisture, you know to empty your tray.

what if the tray was the way to detect moisture level? or, you could drip it back into the supply water?
