I'm hoping the Lounge is an off-topic enough area to ask for advice, because admittedly, this is rather far from the topic of Hubitat. However, this forum is full of all sorts of DIY folks who are experienced in automating their homes, and this is a home automation sort of question.
I have a Jura E8 espresso machine. It's placed right next to a Drinkpod water filter heater/cooler dispenser. The Drinkpod allows secondary output line of ambient, but filtered, water intended for coffee makers, ice machines, etc. I put a quick connect valve on it and use it for when I need to fill something with filtered water, such as the reservoir of the espresso machine.
I have to fill the reservoir with every single use lately. It got me looking into trying to use some sort of float valve, to effectively turn the reservoir into the equivalent of a tiny version of your average toilet tank (but hopefully more sanitary than that description). I tried a few options, including kits sold specifically to do this for a coffee maker (Nespresso is one common example), and sadly, there just doesn't seem to be a float valve out there that is small enough to do the job.
Jura seems to know there's a need for this, but only for certain models, which don't include the E8. On top of that, the Jura solution, is priced at a whopping $800. If they ever make such a solution for the E8 (doubtful), it would likely be at a similar insane price point.
Does anyone have any advice on this? I have recently started looking into, of all things, aquarium top off systems and even auto watering systems, but not found anything ideal for the job.
A corollary to this that might be more on topic, I have a Jura Smart Connect module in the E8. It communicates through Bluetooth, and I'm itching to see what ridiculous home automation I could possibly eek out of it, but having a hard time. There are some projects I see on github, but they are of the arcane command line sort that present a significant learning curve for me. Anyone ventured down that path?
