Built this with two of my favourite bitcoin gadgets!
My BTClock (nprofile…c0uu) lights up when sats come in.
Purple and orange for a Nostr zap.
Pink and orange when someone fills the LightningPiggy (nprofile…fhxk)
The rest of the day the LEDs follow the price: euro on the left, dollar on the right, green or red.
Home Assistant ties it together. My phone pings and the kitchen speaker says who zapped.
Thanks Richard (nprofile…2wav) for the Piggy and Djuri (nprofile…nw9g) for the BTClock API that made this possible.
Full how-to, with a copy-paste prompt:
