A library to use an Arduino as a master to control and communicate via modbus with GroPoint soil moisture sensors. Depends on the EnviroDIY/SensorModbusMaster library.
This library is available through both the Arduino and PlatformIO library registries. Here is the PlatformIO registry page. Use the Arduino IDE to find the library in that registry. The build and ingest logs for this library into the Arduino library registry are available here.
