I finally set Conference B to cut lighting by 15% after 10 pm, and the motion sensor now decides the slowest sun salutation equals “empty room” and blackouts the class every three minutes. Anyone else saving kilowatts and getting booed by tranquil people?
Is it PIR or dual-tech? Bump hold time to 15 minutes after 10 pm; PIR misreads “three minutes” yoga.
Been there — . If you can tweak the after-10 pm profile, set that zone to partial-off so instead of blackout it holds about 30% during the “slowest sun salutation,” and mask the lower third of the PIR lens with a bit of tape so it stops tracking floor-level movement. @OP if you’ve got BMS scheduling, can you pin that class block as occupied and let the sensors do their thing the rest of the night?
@oliverT99 we fixed this by wiring the instructor’s AV “start class” button to trigger a timed 35% lighting scene (we set 50 minutes) via a dry contact, then it hands control back to the sensor when the timer ends; do you have a spare GPIO on the rack?
Try relocating the PIR to a side wall aimed across the mats (or rotate the ceiling unit 20–30°); PIR reads “lateral movement” much better than toward/away, so slow flows hold the lights. Like a cat, it notices side-to-side more than zen stillness; this guide shows the patterns: https://www.legrand.us/-/media/brands/wattstopper/resources/application-guides/ws-occupancy-sensors-application-guide.ashx. What sensor model are you on so we can check lens options?
Piggybacking on @kelsey_ryder92, turn on a ‘grace fade’ before off: drop to about 25% for 90–120 seconds and only kill the lights if no motion returns — like a polite last call instead of a blackout. Just confirm your egress minimum so that dim level is compliant; does your controller support that?
