I was thinking a good product may be a shower head that limits water use, something like the “shower manager”. Basically it would let the water run for X minutes, then warn Y minutes before shutting it off, then shut the water off and not allow water for Z minutes. Some of these devices don’t actually shut the water off, they might limit it to 75% instead. Maybe allow the app to reset it and control the values. This would basically be used for those of us with teenagers who spend an eternity in the shower. Anyhow, thought with all your tech and manufacturing expertise it might be something of interest to roll out. Keep on doing a great job with all your gadgets!
A showerhead would be nice as long as it has a manual override if the wifi goes down. But a mixing valve would be even better - it would need to be plumbed in but would give the user more than just on/off control. It could raise/lower the temp, be set for individual temperature or pressure preferences, and would have no effect on the aesthetics (you could have your big rain shower head, we could keep our adjustable pressure head). Moen has one but at nearly $400 it is not a realistic option for most people.

I wouldn’t want it to rely on wifi other than maybe to initially configure it. Once configured it’d just need enough power to time itself and open the valve. A mixer could be cool but personally that’d not what I’m suggestion, a mixer would need a much more complex install. I just want to be able to unscrew the shower head, screw this on, and/or screw the shower head back on to it. If I have to pull apart the wall it’s a no-go for me. If it’s just a mixer replacement, maybe if it’d fit in my current plumbing. But I’m definitely not looking for this to be a plumbing project, I’d want it to be more of a screw off the old, screw on the new thing.
