@nono8223 I think it will be a good idea as long as there are people actively developing & supporting the platform now and in the future.
Recently the Raspberry Pi port (or Linux, in general) has been updated and included in the core library, so MySensors is no longer Arduino-only.
@Søren-Heide-Larsen different networks can be achieved by setting different channels / network ID.
See here for NRF24 and here for RFM69.
There is no pairing function in MySensors.
Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse.
Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements.
The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.
