Yeah that's what I do with the met office map the forecast is terrible 😁. I think nostr is most underutilised for microcontroller devices. But its a bit of a chicken and egg situation with that atm because most people using btc/lightning on nostr are generally spread far apart geographically. So unless you have a use case where its some you observe over the internet (like lightning goats) or it starts say a manufacturing process its still lacking a major use case for now. Perhaps normies using btc on square might help consumers realise they can use it with no friction and finally open up nostr bitcoin mass market products/services.
