The stack:
- Raspberry Pi
- Satoshkey relay card (self-developed, available at cost price)
- payTolo — Lightning payment listener, runs locally on the Pi
- Any Lightning wallet

How it works:
→ QR code displayed next to a physical device
→ scan with any Lightning wallet
→ send 100 sats (~$0.06)
→ Pi receives payment instantly
→ GPIO triggers relay card
→ device activates

Demo: a model locomotive that starts rolling on payment.

No subscription. No 3rd party dependencies. Open source. Configurable via web interface.
