Firmware & Changelog (Pressure Sensor LoRaWAN)

Pressure Sensor LoRaWAN

There exist different Variants of our Hardware with Pressure Probes, because there exist very different Pressure Probes for different situations. Please make sure to install the correct firmware for your Hardware. You can see which firmware your device is running, by checking the log with our config adapter, while the device is booting.
