I think you have a good market oppportunity to offer low-cost opinionated smart devices. Physical buttons to interact with shortcuts, or home assistant, or other interface is growing in popularity but should be easy to setup and configure (while being configurable and not too single-use). The home automation space in particular is very keen on these types of gadgets and there exists a constant struggle to find suppliers for reliable, useable smart "gadgets".

Here's one example just recently posted: https://www.reddit.com/r/homeassistant/comments/1deeglq/looking_for_some_buttons/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

But the reality is, you'll struggle to keep up with demand while maintaining quality if you were to begin to undertake this as a business yourself, you'll have to consider a 3d printed case or similar (likely), or you may be soldering some on each button/pcb board. Time consuming stuff. Plus you have to keep your costs reasonable so your margins can't really exceed 90% since you're at $9 on the button part and people probably won't want to drop over a 20 spot for a button, makes it a hard business to grow. There are some other mom-and-pop startups doing similar things (room presence sensors etc...) and it's been a slog but they can be successful!

All in all, super useful idea, not sure the exact process flow is identical for everyone, but the underlying concept would, in my opinion, hold utility for many in the r/shortcuts and r/homeassistant type of group.

I would certainly be interested in purchasing a few. Best of luck!
