Smart Home Health Monitoring: Integrating 3 Key Metrics with IoT
First-generation elderly Smart Homes focused on physical safety — falls, gas leaks. The next generation integrates proactive health data, connecting medical devices with IoT ecosystems so families can monitor health in real time.
Metric 1: Blood Pressure
Compatible devices:
- Omron HEM-7156 or Bluetooth-capable models (2,500–4,500 THB)
- Connects to Google Health or Apple Health
- Via Home Assistant integration → LINE Notify
Automation rule: If blood pressure reading >180/120 mmHg → immediate LINE alert to family If 3 consecutive readings remain high → prompt to call 1669
Alert thresholds: High: SBP >140 or DBP >90 (warning alert) Critical: SBP >180 or DBP >120 (emergency alert)
Family Dashboard: daily and weekly blood pressure graphs, trend analysis, reading time logs correlated with medication records.
Metric 2: Blood Glucose
For elderly with diabetes (30% of Thai elderly over 65)
Compatible devices:
- Accu-Chek Instant S or One Touch Bluetooth models (1,500–2,500 THB)
- Continuous Glucose Monitor (CGM) such as FreeStyle Libre 2 (7,000–9,000 THB/month disposable)
Automation rules: Hypoglycemia (<70 mg/dL) → immediate emergency alert (high danger) Hyperglycemia (>250 mg/dL) → alert + entry in daily report
Integration path: Bluetooth Glucose Meter → Phone App → IFTTT/Home Assistant → LINE Notify to family. Every reading auto-logged in daily report.
Metric 3: Sleep Quality
No wearable needed — mmWave does it
mmWave 60GHz directly measures:
- Respiration rate during sleep (normal 12–20 breaths/minute)
- Heart rate during sleep (normal 50–70 bpm)
- Sleep stages (Light/Deep/REM) via algorithm
- Restlessness score (body movement count per night)
Morning LINE report:
- Last night slept X hours (normal/below normal)
- Average heart rate X bpm (normal/abnormal)
- Average respiration X breaths/minute
- Turned over X times (high = sleep disruption)
Health correlation: If Restlessness is high for 3 consecutive nights AND blood pressure is above normal → system recommends family arrange a doctor visit.
Family Health Dashboard
All 3 metrics in one view:
- Blood pressure: 7-day graph + trend (rising/falling/stable)
- Glucose: latest reading + today’s graph (if CGM)
- Sleep: summary score + observations
- Medication: checked/not taken
- Activity: Active / Quiet / Abnormal inactivity
