Bathroom Gang Plan

Apartment 2306 · Jun 2026 · Draft — to be finalized

Design principle: Physical wired switch for primary loads — works without HA. Zooz ZEN51LR relays hidden in J-box for secondary loads (fan, Airmada, cans) — direct Z-Wave association for local fallback, HA for timers and automation.

After: Heat → dedicated 20A switch (gang 1). Shower fan → ZEN71 paddle (gang 2). Shower cans → ZEN35 dimmer (gang 3). Leila's mirror + cans → ZEN35 dimmer + ZEN51LR relay (gang 4). Airmada → ZEN51LR hidden relay in J-box, triggered by ZEN35 (gang 3) btn 2 + HA timed drying sequence.

✓ No-HA fallback: ZEN35 btn 1 direct Z-Wave association → ZEN51LR (works without HA) · ZEN35 paddle always controls full circuit (mirror + cans together)
ZEN35 paddle: dims full circuit — mirror at X% + cans pass dimmed signal through ZEN51LR when relay is on
ZEN35 btn 1 (CANS): direct Z-Wave assoc → ZEN51LR on/off (no HA needed) · also fires Central Scene event → HA for advanced automation
Total load: Banda 24 21W + 3 cans ~36W = 57W — within ZEN35 150W LED limit ✓
Hidden in J-box — no gang
Airmada blowers (air jets)
ZEN51LR relay · ZEN35 (gang 3) btn 2 direct Z-Wave assoc · HA timed drying sequence after shower · no dedicated gang needed
Leila's can lights
ZEN51LR inline relay · passes dimmed signal from ZEN35 paddle · ZEN35 (gang 4) btn 1 (CANS) direct Z-Wave assoc → on/off independently from mirror
