Congrats! Happy for your success. Your mix of ingredients is impressive (the hardware alone is probably simple). Your product idea came from actual personal need (validation!), and you are able to tie the hardware to your software to widen the moat -- which is great.

Your anti-counterfeiting tech hopefully / probably prevents your Chinese manufacturers / suppliers / related entities from free-riding on your work. (If your volumes start hitting say 50K+, things may change, you may be entering dangerous territory then, so I'd suggest you spend some time on beefing up the moat).

Good luck towards 10K volume!
