Yeah i use the arduino ide on my nodemcu. Im testing the sensor with the yosemite displayvalues library.
The thing i meant with own code was that the one working on this project before didnt give me
Yeah i use the arduino ide on my nodemcu. Im testing the sensor with the yosemite displayvalues library.
The thing i meant with own code was that the one working on this project before didnt give me anything like source code or explenation how he did work everything out.
Its searching all the slaveids and cant find the sensor. I use pin D6 for rx and d5 for tx but it just says it cant find the sensor.
The sensor im using is either a y-500b/y-1002 or y-2002. Im not quite sure. Dont really know what to do at this point because i know how modbus works everything is wired correctly and it uses a levelconverter.
