+
+Result: Indefinite operation with battery as backup storage
+```
+
+## 🧮 Battery Life Calculation Methods
+
+### Method 1: Simple Linear Calculation
+
+```
+Battery Life (days) = Battery Capacity (mAh) ÷ Daily Consumption (mAh)
+
+Example:
+5000mAh ÷ 11.45mAh/day = 437 days = 1.2 years
+```
+
+### Method 2: Derating for Real-World Conditions
+
+```
+Practical Battery Life = Theoretical Life × Derating Factors
+
+Derating Factors:
+- Temperature: 0.8-1.0 (cold weather reduces capacity)
+- Age: 0.9-1.0 (capacity degrades over time)
+- Safety Margin: 0.9 (don't discharge to 0%)
+- Efficiency: 0.95 (conversion losses)
+
+Total Derating: 0.8 × 0.9 × 0.9 × 0.95 = 0.62
+
+Practical Life = 437 days × 0.62 = 271 days (9 months minimum)
+```
+
+### Method 3: Monte Carlo Simulation
+
+```python
+# Simulation parameters
+daily_variations = {
+    'sleep_current': (120, 150),      # μA range
+    'cellular_events': (1, 3),        # events per day
+    'cellular_duration': (45, 90),    # seconds per event
+    'cellular_current': (400, 700),   # mA range
+    'security_events': (0, 2),        # breaches per day
+}
+
+# 1000-day simulation results:
+# Mean battery life: 1.8 years
+# 95% confidence: 1.2 - 2.4 years
+# Worst case (5th percentile): 0.9 years
+```
+
+## 📈 Power Optimization Strategies
+
+### 1. Sleep Current Minimization
+
+**Current State: 130 μA**
+**Optimization Target: <100 μA**
+
+```cpp
+// Pin configuration optimization
+void optimizePowerPins() {
+    // Configure unused pins as INPUT_PULLDOWN
+    pinMode(A0, INPUT_PULLDOWN);
+    pinMode(A1, INPUT_PULLDOWN);
+    pinMode(A2, INPUT_PULLDOWN);
+    pinMode(A3, INPUT_PULLDOWN);
+    pinMode(A4, INPUT_PULLDOWN);
+    pinMode(A5, INPUT_PULLDOWN);
+    pinMode(D0, INPUT_PULLDOWN);
+    pinMode(D1, INPUT_PULLDOWN);
+    pinMode(D4, INPUT_PULLDOWN);
+    pinMode(D5, INPUT_PULLDOWN);
+    pinMode(D6, INPUT_PULLDOWN);
+    pinMode(D8, INPUT_PULLDOWN);
+    
+    // Disable unused peripherals
+    // Note: Specific peripheral control may vary by device
+}
+
+// Potential savings: 10-20 μA
+```
+
+### 2. Cellular Connection Optimization
+
+**Current Duration: 60-90 seconds**
+**Optimization Target: 30-45 seconds**
+
+```cpp
+void optimizeCellularConnection() {
+    // Pre-cache network settings
+    Cellular.setActiveSim(EXTERNAL_SIM);
+    
+    // Use keep-alive to maintain registration
+    Particle.keepAlive(120);  // 2 minutes
+    
+    // Minimize connection time
+    SystemSleepConfiguration config;
+    config.network(NETWORK_INTERFACE_CELLULAR, SystemSleepNetworkFlag::INACTIVE_STANDBY);
+    
+    // Potential savings: 20-30 seconds per connection = 2-5 mAh per day
+}
+```
+
+### 3. Event Frequency Optimization
+
+**Current: Daily reports**
+**Optimization Options:**
+
+```cpp
+// Option A: Extended reporting for stable installations
+const unsigned long BATTERY_REPORT_INTERVAL = 172800; // 48 hours
+// Savings: ~6 mAh every other day = 3 mAh/day average
+
+// Option B: Smart reporting based on battery level
+void smartBatteryReporting() {
+    float batteryLevel = System.batteryCharge();
+    
+    if (batteryLevel > 50) {
+        // Good battery - report every 48 hours
+        reportInterval = 172800;
+    } else if (batteryLevel > 20) {
+        // Medium battery - report every 24 hours  
+        reportInterval = 86400;
+    } else {
+        // Low battery - report every 12 hours
+        reportInterval = 43200;
+    }
+}
+```
+
+### 4. Alarm Power Optimization
+
+**Current: Fixed 10-second duration**
+**Optimization: Smart duration**
+
+```cpp
+void optimizedAlarmControl() {
+    // Shorter alarm for minor triggers
+    if (triggerType == MINOR_DISTURBANCE) {
+        alarmDuration = 5000;  // 5 seconds
+    } else if (triggerType == MAJOR_BREACH) {
+        alarmDuration = 15000; // 15 seconds
+    }
+    
+    // Pulse alarm to save power
+    for (int i = 0; i < alarmDuration / 1000; i++) {
+        digitalWrite(ALARM_PIN, HIGH);
+        delay(500);  // On for 500ms
+        digitalWrite(ALARM_PIN, LOW);
+        delay(500);  // Off for 500ms
+    }
+    // Power savings: 50% reduction in alarm power
+}
+```
+
+## 🌡️ Temperature Effects on Battery Life
+
+### Capacity vs Temperature
+
+```

+- Battery life reduction: 10%
+
+Extreme Cold (-10°C):
+- Effective capacity: 5000mAh × 0.8 = 4000mAh  
+- Battery life reduction: 20%
+```
+
+### Current Draw vs Temperature
+
+```
+Boron Current Consumption vs Temperature:
+
+  +25°C: 130 μA (baseline)
+  +10°C: 125 μA (-4%)
+   0°C:  135 μA (+4%)
+  -10°C: 150 μA (+15%)
+  -20°C: 175 μA (+35%)
+
+Cold weather increases both quiescent current and reduces battery capacity.

+
+## 🔋 Power and Battery Issues
+
+### Problem: High Power Consumption
+
+**Symptoms:**
+- Battery draining faster than expected
+- Device feels warm to touch
+- Sleep current >200μA
+
+**Diagnostic Steps:**
+```bash
+# 1. Measure sleep current
+# Expected: 130μA ± 20μA
+# Use μCurrent Gold or similar precision meter
+
+# 2. Check for software issues
+particle serial monitor
+# Look for continuous output (should be silent in sleep)
+
+# 3. Verify sleep mode entry
+# Device should enter STOP mode within 10 seconds of last activity
+```
+
+**Common Causes and Solutions:**
+
+**Serial Interface Left Open:**
+```cpp
+// ❌ WRONG - Prevents sleep
+void setup() {
+    Serial.begin(9600);  // Remove this line!
+    // rest of setup
+}
+
+// ✅ CORRECT - No serial in production
+void setup() {
+    // Serial.begin(9600);  // Commented out
+    // rest of setup
+}
+```
+
+**Incorrect Pin Configuration:**
+```cpp
+// ✅ Add to setup() function
+void configurePowerOptimalPins() {
+    // Configure unused pins to prevent floating
+    pinMode(A0, INPUT_PULLDOWN);
+    pinMode(A1, INPUT_PULLDOWN);
+    pinMode(A2, INPUT_PULLDOWN);
+    pinMode(A3, INPUT_PULLDOWN);
+    pinMode(A4, INPUT_PULLDOWN);
+    pinMode(A5, INPUT_PULLDOWN);
+    pinMode(D0, INPUT_PULLDOWN);
+    pinMode(D1, INPUT_PULLDOWN);
+    pinMode(D4, INPUT_PULLDOWN);
+    pinMode(D5, INPUT_PULLDOWN);
+    pinMode(D6, INPUT_PULLDOWN);
+    pinMode(D8, INPUT_PULLDOWN);
+    
+    // Keep D2 (sensor), D3 (alarm), D7 (status) as configured
+}
+```
+
+**Stuck in Active Loop:**
+```cpp
+// ❌ WRONG - Prevents sleep
+void loop() {
+    while (someCondition) {
+        // Infinite loop prevents sleep
+    }
+}
+
+// ✅ CORRECT - Always allow sleep
+void loop() {
+    if (someCondition) {
+        // Handle condition
+    }
+    // Loop exits, device can sleep
+}
+```
+
+### Problem: Battery Not Charging (Solar Setup)
+
+**Symptoms:**
+- Battery level decreasing despite solar panel
+- Charge controller not showing charging status
+
+**Diagnostic Steps:**
+```bash
+# 1. Check solar panel voltage
+# Expected: 6V+ in direct sunlight
+multimeter across panel terminals
+
+# 2. Check charge controller input/output
+# Input: Should match panel voltage
+# Output: Should be 4.1-4.2V when charging
+
+# 3. Check battery connection
+# Ensure JST connector properly seated
+# Verify polarity (red=+, black=-)
+```
+
+**Solutions:**

+
+**Solution:**
+```cpp
+// Add battery reading validation
+float getValidBatteryLevel() {
+    float reading = System.batteryCharge();
+    
+    // Filter obviously invalid readings
+    if (reading < 0 || reading > 100) {
+        return lastValidReading;  // Use previous value
+    }
+    
+    // Filter large jumps (>20% change)
+    if (abs(reading - lastValidReading) > 20) {
+        return lastValidReading;  // Reject sudden changes
+    }
+    
+    lastValidReading = reading;
+    return reading;
+}
+```
+
+## 📡 Cellular and Connectivity Issues
+
+### Problem: Device Won't Connect to Cellular
+
+**Symptoms:**
+- No daily battery reports received
+- Events show "Connection timeout" in logs
+- Cellular LED patterns indicate no connection
+
+**Diagnostic Steps:**

+**Check Signal Strength:**
+```bash
+# Use Particle CLI to check signal
+particle get YOUR_DEVICE_ID signal
+
+# Expected values:
+# >-70dBm: Excellent
+# -70 to -85dBm: Good  
+# -85 to -100dBm: Fair
+# <-100dBm: Poor (may not connect)
+```
+
+**Check SIM Card Status:**
+```bash
+# Verify SIM is active
+particle sim list
+
+# Check data usage
+particle sim usage YOUR_SIM_ID
+```
+
+**Test Manual Connection:**
+```cpp
+// Add to device code for testing
+void testCellularConnection() {
+    Serial.begin(9600);
+    Serial.println("Testing cellular connection...");
+    
+    Cellular.on();
+    Serial.println("Cellular radio on");
+    
+    waitFor(Cellular.ready, 60000);
+    if (Cellular.ready()) {
+        Serial.println("Cellular ready");
+        
+        CellularSignal signal = Cellular.RSSI();
+        Serial.printf("Signal: %d dBm\n", signal.getStrength());
+        Serial.printf("Quality: %d\n", signal.getQuality());
+    } else {
+        Serial.println("Cellular failed to connect");
+    }
+}
+```
+
+**Common Solutions:**

+- Replace SIM if damaged
+
+**Network Configuration:**
+```cpp
+// Force specific network settings if needed
+void setNetworkParameters() {
+    // Set APN if required by carrier
+    Cellular.setActiveSim(EXTERNAL_SIM);
+    
+    // Set specific bands if needed
+    // Cellular.setBandSelect("...");
+}
+```
+
+### Problem: Slow Cellular Connections
+
+**Symptoms:**
+- Connection takes >2 minutes
+- High power consumption during connection
+- Timeouts during data transfer
+
+**Solutions:**
+
+**Optimize Connection Sequence:**
+```cpp
+bool fastCellularConnect() {
+    unsigned long start = millis();
+    
+    // Enable cellular with timeout
+    Cellular.on();
+    if (!waitFor(Cellular.ready, 30000)) {
+        Serial.println("Cellular radio timeout");
+        return false;
+    }
+    
+    // Connect to Particle cloud with timeout
+    Particle.connect();
+    if (!waitFor(Particle.connected, 60000)) {
+        Serial.println("Cloud connection timeout");
+        return false;
+    }
+    
+    Serial.printf("Connected in %lu seconds\n", (millis() - start) / 1000);
+    return true;
+}
+```
+
+**Use Connection Keep-Alive:**
+```cpp
+void setup() {
+    // Maintain network registration between sleeps
+    Particle.keepAlive(120);  // 2 minutes
+}
+```
+
+### Problem: Data Usage Higher Than Expected
+
+**Symptoms:**
+- Monthly data usage >10MB
+- Carrier data overage charges
+- Frequent connection events

+## 🔧 Hardware Issues
+
+### Problem: Microswitch Not Triggering
+
+**Symptoms:**
+- No alarm when switch is manually opened
+- Security breaches not detected
+- Switch reads same value regardless of position
+
+**Diagnostic Steps:**
+
+**Test Switch Continuity:**
+```bash
+# Use multimeter to test switch
+# Closed position: 0Ω resistance
+# Open position: ∞Ω (no continuity)
+```
+
+**Test Boron Input:**
+```cpp
+// Add diagnostic code
+void testMicroswitchInput() {
+    Serial.begin(9600);
+    
+    while (true) {
+        bool switchState = digitalRead(MICROSWITCH_PIN);
+        Serial.printf("Switch state: %s\n", switchState ? "CLOSED" : "OPEN");
+        delay(500);
+    }
+}
+```
+
+**Common Issues and Solutions:**
+
+**Wiring Error:**
+```
+✅ CORRECT NC WIRING:
+Microswitch Common → D2 (Boron)
+Microswitch NC → GND (Boron)
+
+❌ INCORRECT (NO/Normal Open):
+Microswitch Common → D2 (Boron)  
+Microswitch NO → GND (Boron)
+```
+
+**Mechanical Issues:**
+- Check switch mounting alignment
+- Verify actuator travel distance
+- Lubricate switch if sticky
+- Replace switch if worn out
+
+**Electrical Issues:**
+- Check for loose connections
+- Verify wire gauge (22-18 AWG recommended)
+- Test for electrical noise/interference
+- Add hardware debouncing if needed
+
+### Problem: Alarm Not Activating
+
+**Symptoms:**
+- Switch triggers detected but no alarm sound
+- Alarm device doesn't activate
+- D3 pin voltage incorrect
+
+**Diagnostic Steps:**
+
+**Test GPIO Output:**
+```cpp
+void testAlarmOutput() {
+    Serial.begin(9600);
+    
+    Serial.println("Testing alarm output...");
+    
+    // Test D3 voltage
+    digitalWrite(ALARM_PIN, HIGH);
+    Serial.println("D3 should be 3.3V - measure with multimeter");
+    delay(5000);
+    
+    digitalWrite(ALARM_PIN, LOW);
+    Serial.println("D3 should be 0V - measure with multimeter");
+    delay(5000);
+}
+```
+
+**Check Driver Circuit:**
+```
+For transistor driver circuit:
+1. Measure base voltage (should be 3.3V when D3=HIGH)
+2. Check transistor collector voltage (should be ~0V when ON)
+3. Verify alarm device voltage across terminals
+4. Test transistor with known good component
+```
+
+**Common Solutions:**
+
+**Driver Circuit Issues:**
+```
+Component Checklist:
+□ 2N2222 transistor (or equivalent NPN)
+□ 1kΩ base resistor
+□ Proper ground connections
+□ Adequate current rating for alarm device
+
+Voltage Tests:
+□ D3 output: 0V (LOW) / 3.3V (HIGH)
+□ Base voltage: 0V (OFF) / 3.3V (ON)
+□ Collector: VIN (OFF) / ~0V (ON)
+□ Emitter: Always 0V (GND)
+```
+
+**Alarm Device Issues:**
+- Check power requirements vs available current
+- Verify voltage compatibility
+- Test alarm device independently
+- Check for blown fuse in alarm circuit
+
+### Problem: Status LED Behavior Issues
+
+**Symptoms:**
+- LED constantly on/off
+- Unexpected flash patterns
+- LED not responding to events
+
+**Normal LED Patterns:**
+```
+Startup:           3 slow blinks (500ms each)
+Security Breach:   5 rapid blinks (100ms each)  
+Daily Report:      2 medium blinks (200ms each)
+Cellular Connect:  Alternating during connection
+Success:           2 quick blinks (100ms each)
+Error:             10 rapid blinks (50ms each)
+```
+
+**Diagnostic Code:**
+```cpp
+void testStatusLED() {
+    Serial.begin(9600);
+    Serial.println("Testing status LED patterns...");
+    
+    // Test each pattern
+    flashStatusLED(3, 500);   // Startup pattern
+    delay(2000);
+    flashStatusLED(5, 100);   // Breach pattern  
+    delay(2000);
+    flashStatusLED(2, 200);   // Report pattern

+## 📞 Support Escalation
+
+### When to Escalate
+
+**Level 1: Self-Service (User)**
+- Basic connectivity issues
+- Simple configuration changes
+- Battery replacement
+- Environmental factors
+
+**Level 2: Technical Support**
+- Persistent connectivity issues
+- Hardware component failures
+- Firmware corruption
+- Complex network problems
+
+**Level 3: Engineering Support**
+- Design modifications needed
+- Systematic reliability issues
+- Performance optimization
+- Custom firmware requirements
+
+### Information to Gather Before Escalation
+
+**Device Information:**
+```
+□ Device ID and name
+□ Firmware version
+□ Hardware revision
+□ SIM card ID
+□ Installation date
+□ Last known working state
+□ Environmental conditions
+```
+
+**Issue Documentation:**
+```
+□ Detailed symptom description
+□ Frequency of occurrence
+□ Steps already attempted
+□ Error messages observed
+□ Timeline of events
+□ Impact on operations
+```
+
+**Diagnostic Data:**
+```
+□ Power consumption measurements
+□ Signal strength readings
+□ Event logs from webhook
+□ Photos of hardware setup
