People also just need to be more selective about where and how they automate.
For example, I wanted my coffee to automatically start in the morning. So instead of buying a “smart” coffee maker, I bought the dumbest possible one and a smart switch. Now, no matter what happens with that switch, the worst that can happen is I have to manually hit a button to get coffee.
I assume lack of demand. In your own home, you’d be keeping the handle clean, and public washrooms often use the touchless sensor types.
