+// TODO / wishlist

+// ## more hardware support/use
+//
+// * rtc initialization, and/or NTP query, to print times.
+//   - maybe we can just convert the time steps from the returned data set, and e.g. do x axis ticks on multiples of 3hours from that
+// * wifi
+// * tls
+// * json parser
+// => fetch data from https://api.energy-charts.info/price?bzn=DE-LU
+//
+//
+// ## drawing prettier
+// * chrono: timestamp -> datetime<utc> -> .hours() % 3 == 0, then x-axis tick
