Currently this platform is also available with an external 4 or 5 pin header (100kHz I2C) to connect external sensors (up to 2m cable) to it. As of now it only has support for an external temperature/humidity sensor board.

In the course of the year it will support external ambient light measurements (in LUX).

Experiments with LoRa are also planned for 2023, especially with spreading factor SF5. The goal is to communicate via LoRa without affecting battery lifetime. This is like trying to take a shower without getting wet, but this won't keep me from trying it.
