Cold/Heat Micro-Adjustments for Tiny-House Smart Locks

Small volume = fast temperature swings. Tune for both ends of the thermometer.

1) Winter Micro-Tune

Strike depth: back off 0.5–1 mm to reduce bind on cold mornings.
Lubricant: PTFE/silicone rated to −40 °C on latch faces; avoid thick oils.
Battery: lithium AAs or indoor-mounted 12→5 V buck; keep cells warm side of door.

2) Summer Micro-Tune

Retorque screws after first heat wave; plastics relax in sun.
Dim keypad brightness; heat-soaked housings draw curious insects (and power).
Vent enclosed boxes with breathable membranes to prevent outgassing fog.

3) Fast Swing Protocol

After big HVAC changes (heater on/off, AC blast), cycle lock 3× and listen for scrape; adjust strike if needed.
Door material matters: wood moves most, composite/metal less — schedule checks accordingly.

4) Power Budget Nudges

Winter design to worst sun hours; summer reduce idle features.
Keep buck converters near the lock to minimize voltage drop during motor start.

Treat alignment as a seasonally-adjusted setting. Two minutes of tuning beats months of annoyance.
