Pollen lockout that closes windows before the count spikes Using a local pollen sensor plus a 3-hour forecast, the automation closes windows 40 minutes before a predicted spike and hands ventilation to the HEPA supply unit, then reopens when the outdoor count falls below 20 grains/m³ for 30 minutes. wifi 2400000 ms Radiator-by-radiator balancing from room temperature curves Thermostatic valves on seven radiators learn each room's heating curve over two weeks, then trim the valve position to hold ±0.4 °C instead of ±1.6 °C, which cut gas use by 12 % in a leaky 1970s flat. zwave 1200000 ms Whole-flat CO₂ purge with a 9-minute cross-ventilation window Four CO₂ sensors across the flat trigger a 9-minute cross-ventilation on the two opposite windows when the mean reading passes 1 100 ppm, then re-check and repeat up to three times. Air changes measured at 4.1 ACH during the open phase. thread 540000 ms Night cooling purge that pulls in cool air only when it helps On summer nights the bedroom window opens automatically only when outdoor air is at least 3 °C cooler than indoors and indoor CO₂ is above 900 ppm, closing at 05:30 or when outdoor temperature rises within 1.5 °C of indoor. matter 180000 ms Bathroom fan that runs until the humidity gradient flattens The fan does not run for a fixed 20 minutes. It runs until the absolute humidity stops falling, which is typically 11 minutes after a 4-minute shower and 26 minutes after a bath — a 38 % reduction in fan runtime over a timed schedule. zigbee 2000 ms
