The battery interrupt code above is built into device OS now, and it's much better to get the is battery powered state from device diagnostics. This code can be used instead of the code above:

Boron Battery Connected

OK, this is a much better way to do it, using the DiagnosticsHelperRK library. I added a new example to the library for power source: #include "Particle.h" #include "DiagnosticsHelperRK.h" SerialLogHandler logHandler; unsigned long lastPublish = 0; int lastPowerSource = -1; void setup() { Serial.begin(); } void loop() { int powerSource = DiagnosticsHelper::getValue(DIAG_ID_SYSTEM_POWER_SOURCE); if (powerSource != lastPowerSource) { if (millis() - lastPublish >= 1000 && Particle.conne…
