Using a USB-relay module like in this setup, you can build a zap-watcher to turn on any USB gadget. With https://niot.space you can create an LNURLp QR code for people that have lightning-wallets but don't use #nostr (paying that QR code will generate a zap event from nostr:npub1cyjewcsx6ze7ulvgumsuk9k26zkuj3ngjzc48y8s4rc3h5jf89vq33zhpt ).
