4. SI7021 with Nodemanager

SI7021 with Nodemanager

  • xlibor

    Hi all, today i tested my SI7021 sensors and Nodemanager, but they not working very well.

    After power on sensor, i receive presentation of two channels (temp and humidity), but then i receive only V_TEMP updates and never recived V_HUM, have anyone working sketch with nodemanager or can check my code, i start from template from nodemanager examples, i also checked sensor with my MCP2221 I2C<>USB converter and here it works.

This sketch can be used as a template since containing the most relevant MySensors library configuration settings, 
NodeManager's settings, all its the supported sensors commented out and a sketch structure fully functional to operate with
NodeManager. Just uncomment the settings you need and the sensors you want to add and configure the sensors in before()

    I changed to development version of Nodemanager this remove compilation errors and then found that recomended library from Sparkfun not work. Then i edited header file SensorSI7021.h to work with Adafruit library and it works 🙂
    my SensorSI7021.h:

    /*
