it would literally be a pump with essentially a chip on top to receive and transmit data, and an out line for draining, and an in line for refill....people who have a drip system could essentially use it right out of the gate. you could do a water change from your car at work. lol I don't think the niche market of water changes would get a good kickstart from a crowd fund
LOL, I was joking about funding. I was more on the lines of packaging up a system to essentially create an auto drip system/water change for the mass market. Most systems are put together only for specific set-ups and some folks wouldn't know where to start.
My brother-in-law has a 240G reef where he's automated almost everything. So water out from sump, water in to 5-stage filtration/dosing is all automated. The only thing missing is sand vacuuming, but he has a relatively light bio load. The phone app would be convenient if one wanted to perhaps override the system to change for ad-hoc water changes and monitoring. Else, no need.
