Good news is you are getting stuff. Bad news, is I don't see any data. This makes me think it is on the Tx end. Can you see what is being put out on the Serial on the Arduino? Requires an FTDI cable and the Arduino IDE.

Been busy all summer final got to hooking up a FTDI cable to the Arduino (Grove Mini Pro LP JP1/FTDI) and was getting data off the serial.
Get the following data ( didn't have solar panel connect or the weather modual hooked up at the time but was definitly getting data.

Is there any way to check and make sure the LoRa 433 is getting data? And also the LoRa in the Weather module is connected to a serial (Serial connector on thePi2Grover Board) the LoRa 433 in the Solar module is connected to a Digital (D6/D7 connector on the Grove Mini Pro LP)

All that is set up right.
the LoRa 433(434.0MHz) is transmitting from the SolarMax and the data received on the Raspberrry Pi side matches.

The Issue is the Third HEX which is the protocol_byte = 00
protocol_byte = block1[2] = 0
#protocol_byte = struct.unpack('B', str(block1[2:2]))[0]
protocol_ID = protocol_byte / 10 = 0
protocol_software_version = protocol_byte - protocol_ID*10 = 0
if (config.SWDEBUG):
print("protocol_ID = ", protocol_ID) = 0
print("protocol_software_version = ", protocol_software_version) = 0
which prints
('protocol_ID = ', 0)
('protocol_software_version = ', 0)
Causing it to fall through to the code that prints
unknown or non-configured protocol received. Protocol = 0
Is there a setting on the solar max I am missing or do I need to download the latest code for the solarmax and update the Grove Mini Pro LP?
I did reset the Variable SOLARMAXPROTOCOL = 0
and changed a few more lines of code so all conditional statements refered to the variable and not to 8 or 10
Got this back after that so it is receiving the data and decoding properly.

I am also not getting Temperature or Humidity it is almost as if the Arduino isn't reading the I2C Bus.

First of all, let's download the latest software for the Arduino mini pro lp. Please capture the version number (from the code start) of the Arduino Mini Pro LP before you reprogram. That gives us some evidence. github.com/switchdoclabs/SDL_Arduino_SolarMAX_LoRa_TxRegarding the protocol setup. The SolarMAX code uses the battery voltage to determine whether it is a LiPo or Lead version. It should pick protocol 8. Here is the code: // Now Set Wireless ID
if (BatteryVoltage < 8.0)
{
WirelessID = 8; // SolarMAX LiPo
}
else
{
WirelessID = 10; // SolarMAX Lead Acid (12V Battery)
}
Protocol = WirelessID * 10 + SOFTWAREVERSION;
I don't see how it could pick zero even if you didn't have a battery connected. I'm thinking this is a software version problem. BP |

I think I confused the issue since I only was looking at the PI side (receive side).

I unplugged the INA3221 and started getting temperature data. My question is on the INA3221 board the SJ1 is unsoldered and the SJ2 is still intact giving it an address of 0x40 which is the same as the HDC1080 board. I'm assuming I need to cut the SJ2 and solder the SJ1 to give it an 0x41 address which I see in the SDL_Arduino_INA3221.h file? Also How do you upload to the Grove Pro Mini LP I tried the FTDI but got and error:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x35
USB doesn't register as a com port I was reading about the ISP and mini do I need to get an ISP device to program from the arduino IDE progrom? I am new to arduino's so not sure how it all works. Previous ardiunos where straight forward just plug in the usb to the computer and program, I am assuming there is a different process with this one. Thanks for all the help, so far.

Solved it!
In the end it was the INA3221 Terminal Board. The default address 0x40 conflicted with the HDC108 Breakout Board 0x40 once I changed the address to 0x41 and replaced the R10 shunt resistor on the INA3221, I burned out by accident, the protocol started transmitting in the string, and there was Battery, Solar, Temperature, and Humidity readings.
Thanks everyone for your help.
PS: The DS3231 RTC is still not being detected but that doesn't seem to affect how it works so I am ignoring that for now.

The next question from me was going to be the wiring and checking what was on the I2C bus. Glad you solved it.
