@SiLeX So it may be due to an incorrect connection? Pins of module are untagged and I connected them according to the positions of schemes that I found online. All modules have same pinout?

@sebdetours said in MDMSPanel "Nextion": Did you take a standart case that you cut out? Hi @sebdetours, yes. This is G1910 (Gainta) box. See drawing attached to projet files.

@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.

Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.

@nrf24_is_hard When I sent data between an Aduino and the RPi I discovered that I have to make the the receiving and the sending structs the same size AND the variables be on 4 byte boundaries. Change your char name[15] to char name[16] Another challenge is that the number of bytes of type int are different. If I remember correctly, Arduino Uno is 2 bytes and RPi is 4 bytes. To make matters worse, some compilers make the least significant byte the first byte of a word and others make it the last byte of a word. eg, sending the value 1 would be received as 16777216 (0x00000001 vs 0x01000000) There are a lot more gotcha's OSD

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.

@AWI I 'm doing a similar project prodias help me make connections as your project and how to perform with I2C
