Show HN: Watering my Christmas tree with ESPHome

Love the project! One thing that would give me the Krepps is to have a 10 liter water bucket next to a mains power outlet. Just thinking about all kinds of ways Murphy could be right here.

Edit: I’m from Europe so for me that feels twice as dangerous. (Don’t know if double the voltage means double the danger though)

It's a cool project. If you don't need a ton of capacity what I did in the past is used a bucket and just some rubber tubing. Once you pull the water through, it will auto-siphon to be the same level as the bucket. Lasted me a week while I was in san diego! :)

Congratulations on your DIY project, posting the commercial version was not at all intended to throw shade on it. I've reverse engineered plenty of commercial products, both for fun and for profit and know the challenges.

HoHoHoH20 has been ok but not perfect. I had to 3D print a secure mount for the probe to fit my tree stand. They don't really include any kind of mount, the probe kind of hangs on hope and prayers.

The pump doesn't develop enough head pressure to lift water more than 8" or so, which it needs to in order to get over the rim of my tree stand. So when the reservoir is getting low, but not empty enough to trigger the low water level alarm, the pump just runs continuously but water does not flow. Found this out because my cat was curious about the pump noise. The easy solution was to put it on an 8" pedestal.

Anecdotally - we have found that Nordsman Fir trees consume a lot less water, drop a lot fewer needles, and have strong branches that can withstand heavy ornaments and cats. Worth seeking out.
