Siloos Scale Calibration

Step 2: Run Serial Diagnostics

ssh -i siloos_key [email protected] "python3 diag_serial.py"

Step 3: Test via WebSocket

Connect to the bridge and observe weight updates:

const ws = new WebSocket('ws://10.0.124.90:8765/?auth=silo-secret');
ws.onmessage = (e) => {
  const data = JSON.parse(e.data);
  if (data.weight !== undefined) console.log('Weight:', data.weight, 'kg');
};

Step 4: Calibrate Gravimetric Dosing

In DoseController.ts (precision dosing engine):

• targetKg: Desired dose in kg (set via DrinkCustomizer stepper)
• tareWeightKg: Weight when brewing starts (auto-captured)
• Auto-stop uses learned flow rate + valve delay + bias correction
• Profile is persisted on Pi, accuracy improves with each dose (±0.1 kg after ~3 doses)
• Key parameters: flowRateKgPerS, valveDelayS, recentOvershootsKg[]
