Converting an Old Thai House to Wellness Smart Home: Three Budget Levels
Most Thai elderly do not want to move house, but existing homes were rarely designed to accommodate changing physical conditions. The question is not whether to rebuild — it is how much to invest to make the existing home safe and smart enough.
30,000 THB — Safety Starter Pack
At this budget, fall prevention and emergency communication take absolute priority.
Devices included: Motion Sensor LED lights for corridor and bathroom at 3 points (3,000–5,000 THB); IPX7 waterproof Panic Button for bathroom and bedside at 2 points (2,500–4,000 THB); PIR Motion Sensor for main hallway (500–800 THB); R11 anti-slip vinyl flooring in bathroom (3,000–6,000 THB including installation); stainless steel grab bars in bathroom at 2 positions (4,000–8,000 THB including installation); Smart Plug for stove control (800–1,500 THB); remaining budget for installation labour and accessories.
Risks covered: bathroom falls; walking in darkness at night; stove left on; inability to call for emergency help.
Remaining gaps: no stationary detection (fallen and not moving); no medication alert; no remote monitoring for family. This level suits elderly who have family at home and need only the most basic safety infrastructure.
60,000 THB — Core Safety and Health Alerts
This level adds precise detection systems and remote family connectivity.
Additional devices (building on Safety Starter): mmWave Sensor bedroom (3,000–5,000 THB); mmWave Sensor bathroom (3,000–5,000 THB); Smart Speaker for voice control and medication reminders (2,000–3,500 THB); Circadian Smart Bulbs, 3 units (1,500–3,000 THB); AI Camera for living room (3,500–6,000 THB); Gas Sensor for kitchen (1,500–3,000 THB); Hub to connect all devices (1,500–3,000 THB).
Additional risks covered: detecting falls while lying still; gas leak detection; real-time family alerts via app; voice control for elderly; reduced respiratory risk from PM2.5.
Remaining gaps: no Smart Bed vital monitoring; no comprehensive health system. However, this level covers 80% of key risks for most elderly living alone.
100,000 THB — Full Wellness Smart Home
This level adds health and wellness systems that turn the home into a personal health management centre.
Additional devices (building on Core Safety): Smart Bed with sleep vital monitoring (25,000–40,000 THB) or Ballistocardiography sensor fitted under existing mattress (5,000–8,000 THB); Keypad Smart Door Lock with Remote App (3,000–6,000 THB); PM2.5 air purifier with automatic sensor (5,000–10,000 THB); Smart Mirror for daily health data display (8,000–15,000 THB); bathroom floor upgrade and Fold-down Bench addition (10,000–15,000 THB including installation).
Outcome: a home delivering 18+ automated daily touchpoints — sleep vitals, air quality, medication management, voice control, and family alerts across all scenarios. Equivalent to mid-tier Full-Service Care, but the elderly person remains in their own home.
Summary: Which Level to Start From
Start at 30,000 THB if unsure, but plan to upgrade to 60,000 THB within 1–2 years. Every device in the Starter Pack remains fully functional in Core Safety, as all connect through the same Hub.
