Sensors

Modbus baud rate : 4800 bauds

Noise sensor modbus address: 0x01 (Usually it is not connected if there is a CO2 sensor)

PM sensor modbus address: 0x02

O3 sensor modbus address: 0x03

NO2 sensor modbus address: 0x04

CO2 sensor modbus address: 0x05 (Usually it is not connected if there is a noise sensor)

Byte 0: CO2 sensor or Noise sensor (Most Significant Byte)
Byte 1: CO2 sensor or Noise sensor (Least Significant Byte)

For instance, byte[0]: 0x82 and byte[1]: 0x02 -> 0x0282 = 642 (642ppm if it is CO2 sensor o 64.2dBA if it is a noise sensor)

Byte 2: PM2.5 sensor (Most Significant Byte)
Byte 3: PM2.5 sensor (Least Significant Byte)
Byte 4: PM10 sensor (Most Significant Byte)
Byte 5: PM10 sensor (Least Significant Byte)

For instance, byte[2]: 0x0F, byte[3]: 0x00, byte[4]:0x10 and byte[5]: 0x00 -> 0x000F = 15 (PM2.5: 15ug/m3) and 0x0010 = 16 (PM10: 16ug/m3)

Byte 6: Temperature's O3 sensor (Most Significant Byte)
Byte 7: Temperature's O3 sensor (Least Significant Byte)
Byte 8: Relative humidity's O3 sensor (Most Significant Byte)
Byte 9: Relative humidity's O3 sensor (Least Significant Byte)
Byte 10: Ozone's O3 sensor (Most Significant Byte)
Byte 11: Ozone's O3 sensor (Least Significant Byte)

For instance, byte[6]: 0x13, byte[7]: 0x01, byte[8]:0xC1, byte[9]:0x01, byte[10]:0x04 and byte[11]: 0x00

0x0113 = 275 (Temperature's value should be divided by 10. T: 27.5ºC)

0x01C1 = 448 (Relative humidity's value should be divided by 10. RH: 44.8%)

0x0004 = 4 (Ozone's value should be divided by 1.96. O3: 2.04ug/m3

Byte 12: NO2_WE value from NO2 sensor (Most Significant Byte)
Byte 13: NO2_WE value from NO2 sensor (Least Significant Byte)
Byte 14: NO2_AE value from NO2 sensor (Most Significant Byte)
Byte 15: NO2_AE value from NO2 sensor (Least Significant Byte)
Byte 16: SO2_WE value from NO2 sensor (Most Significant Byte)
Byte 17: SO2_WE value from NO2 sensor (Least Significant Byte)
Byte 18: SO2_AE value from NO2 sensor (Most Significant Byte)
Byte 19: SO2_AE value from NO2 sensor (Least Significant Byte)

NO2 calculus algorithm from NO2_WE and NO2_AE values

Byte 20: Which sensors have been read. (Bit 0: NO2, bit 1: Noise, bit 2: PM, bit 3: O3, bit 4: CO2)

For instance: 0x1D (00011101b -> NO2, PM, O3 and CO2 sensors have been read and noise has not been read)

Epever's MPPT part

Modbus baud rate : 115200 bauds

Epever's MPPT Modbus Commands

SoC MPPT modbus register: 0x311A

BAT MPPT modbus register: 0x331A

PV MPPT modbus register: 0x3100

LED MPPT modbus register: 0x310C

Byte 21: SoC (battery's state of charge) from Epever's MPPT sensor (Most Significant Byte)
Byte 22: SoC (battery's state of charge) from Epever's MPPT sensor  (Least Significant Byte)

For instance, byte[21]: 0x4C and byte[22]: 0x00. 0x004C -> 76 (SoC: 76%)
