Here are the definitions of each one of the values in the packets:
•
timestamp: When the packet has been received
• model: SwitchDoc Labs SolarMAX
• len: Number of bytes in the packet
• messageid: Reset to 0 on bootup
• deviceid: 1 – If you have more than one SolarMAX2, you can change this ID by recompiling the
software for the MiniProPlus
• protocolversion: Current protocol of the SolarMAX2
• softwareversion: This shows the current version of the software on the Mini Pro Plus
• weathersenseprotocol: 10 for SolarMAX2
The solar data collected by the device is:
•
loadvoltage: Voltage supplied to the Raspberry Pi or other Computer (V)
• batteryvoltage: Voltage of the LiPo Battery (V)
• batterycurrent: Current being supplied by the battery (mA)
• loadcurrent: Current being supplied to the Raspberry Pi or other Computer (mA)
• solarpanelvoltage: Voltage of the Solar Panel (V)
• solarpanelcurrent: Current being supplied by the Solar Panel (mA)
The AuxA variable contains state information about what is going on with the SolarMAX2
Controller. See the values in the next section.
Power Management and Pi Protection in SolarMAX2
A standard solar power controller will not correctly protect your Pi and the SD Card. One has to avoid brown
out conditions and the power turn on and off rapidly. This kills SD Cards.
