Ngl that Thermostat looks pretty sick.
I'm a big fan of the Nostr Market plugin for LNbits. It allows for chat, multiple stores for different product types, a few things like that. You would be out of luck for credit card payments because it's a lightning focused app and If you're comfortable with self-hosting, it's something that you can do as well.
You can play around with it here. https://lnbits.com

My childhood self was taking apart computers at a pretty young age Not putting them back together, of course, but taking them apart.. Id probably want to take it apart and wonder why it's so cool. 😅
If you want one and want to pay in coins, LMK.
You can use your #BTC while it's high and I can get them before they're even higher. 🤣
