Dashy
My own dashboard for the house: temperature, humidity and power usage in one overview.
How warm is it in the house, how humid is the air, and how much power are we using right now? Those answers were spread across separate apps and meters. Dashy brings them together on one screen. By connecting a P1 meter to the meter cupboard and placing an ESP32 with a temperature and humidity sensor in the living room, I collect all the data and push it to my own database on my Raspberry Pi server. This data is then retrieved and displayed by the Dashy PWA.
Seeing everything in one place makes patterns visible: when usage peaks, how fast a room cools down, or when it's time to air the place out.
