In https://downloads.rakwireless.com/ebook/RAK_Catalog_Sensor_Eng_V1.7.pdf, I found:
Two ways to work with 3rd party sensors:
- Pre-attached sensors
RAK integrates some industrial sensors that are widely used in the market through the Probe IO sensor data interface.
- User-selected sensors
The Probe IO also allows users to connect their own sensors through the terminal block.
The first is clear to me, and I tested with success the weather station.
For user-selected sensors the electrical conditions are clear. I can connect the wires of the Sensor via the terminal block. But what about the firmware? Does it mean I must program a customized firmware, or is it possible to configure the SensorHub firmware anyway? It seems, for example, that Modbus RTU is implemented. Can I use it for another sensor with Modbus RTU/RS485 interface, too?
