Custom Electron Solar Panel Connection

@Mquist sorry it’s taken me a few days to respond, I’ve been a bit busy this week.

Waking up the devices is possible, but I don’t think anyone has implemented it. I asked the question previously and it can be found here: Waking up an Electron remotely
Here’s the my main loop of the code where Output is a std::vector and Sleeptime = 900 (for 15 minutes)
Code loop:

void loop(){
  char batt[7];
  delay(5000);
  // Collect data and publish
  if (collectData(I2C_ADDRESS2)){
    float2string(fuel.getSoC(),batt,3);
    Output.push_back(batt);
    Particle.publish("RG", Output[0] + "," + Output[1] + "," + Output[2]);
    Output.clear();
  }
  //sleep
  delay(500);
  // System.sleep(SLEEP_MODE_DEEP,sleepTime,SLEEP_NETWORK_STANDBY); //Uses lots of data
  System.sleep(D3, RISING, sleepTime, SLEEP_NETWORK_STANDBY);
  Wire.begin();
  delay(500);
}

I had the same worries as you and created a post on that as well: Electron Sleep Mode Clarification

Let me know if you have any other questions or need any help. I’d be happy to help.
