So, the website is essentially an HTTP interface for managing an MQTT broker. You create an account, make a "room" (application concept, not part of mqtt), and then put your account name and the room secret phrase into the device (it throws up a captive portal). The device then uses these to connect to the broker to an MQTT topic that's sha256(secret) and from there it's just simply passing messages between devices.
Reminds me of that old Apple Watch feature that’s been lost to time https://www.nbcnews.com/tech/gadgets/heart-heart-apple-watch...
Pretty cute. How'd you get them to pair overseas?
