Tiny House Smart Locks & Compact Power Systems

Because every square foot — and every watt — counts.

1) Why Tiny Homes Need Smart Locks

• 🏡 Space efficiency: one lock can secure multiple access points (main door + storage).
• 🔋 Energy independence: compatible with solar microgrids and battery banks.
• 📱 Convenience: manage access even when power or internet drop out.

2) Common Mounting Types

• Standard deadbolt replacement: Fits most THOW (Tiny House on Wheels) doors.
• Euro-style mortise locks: Often used on converted shipping containers.
• Surface-mount keypads: Great for French or sliding barn-style doors.

3) Power Options (Stay Efficient)

• AA/CR123A cells: Simple, but replace every 6–9 months.
• Micro 12 V feed: Run from lighting circuit via inline fuse (1 A).
• USB-C 5 V feed: If your inverter runs 5 V ports, route one near the door.

Always isolate the circuit with a fused spur and quick-disconnect connector to prevent shorting during maintenance.

4) Weather & Insulation Challenges

Tiny homes often experience wide temperature swings and condensation buildup.

• Seal keypad edges with silicone to avoid corrosion.
• Use closed-cell foam gaskets behind exterior plates.
• Keep control boards away from direct wall insulation spray — moisture can short them out.

5) Security Layering (Smart ≠ Single Point)

• Door frame reinforcement: Small structures flex; use long screws into framing.
• Motion light + alarm link: Add a 12 V PIR sensor feeding a buzzer or LED.
• Bluetooth whitelist: Restrict pairing to trusted devices.

6) Maintenance Checklist

• Test actuation weekly when off-grid.
• Replace batteries before full depletion — voltage dips cause jammed bolts.
• Inspect seals quarterly for condensation or corrosion.
