• Both stations need to be in the same WiFi
• Indoor station runs an MQTT broker
• Outdoor station sends data to MQTT broker
• Indoor station subscribes to it's own topics and display the information
• Outdoor station uses deep sleep (3min) to conserve battery
• 🍰 approximate uptime is stored in RTC memory during deep sleep

Indoor

• Wemos D1 mini
• Waveshare 1.54" e-Paper Display
• USB powered

Outdoor

• Wemos D1 mini
• BME280
• 2x 4000mah Lithium Cells
• Solarpanel
• TP4056 based 18650 charger
• Wire from Bat+ with 100k Ohm resistor to A0 for battery voltage measurements
• Wire from D0 to RST for deep-sleep
