11/7/2023 0 Comments Extractor fan for shower![]() What do I look for when selecting a bath fan? In addition to improved indoor air quality, deterioration of the home is minimized saving the homeowner costly repairs. Occupants will be much more comfortable with proper ventilation. It also helps to remove water vapor that has accumulated on mirrors and walls. What is a bathroom exhaust fan? What does it do?Ī bathroom exhaust fan is a mechanical ventilation device which, when ducted to the exterior of the house, draws out stale, impure and very humid air thereby improving the quality of indoor air.Ī properly installed bathroom exhaust fan will rid the bathroom air of excess moisture, humidity, odors and other pollutants. Good ventilation protects both your health and your home and is especially important in bathrooms which experience high levels of moisture and humidity. Most of today's new homes are highly insulated and practically air tight, saving energy but making proper mechanical ventilation essential to maintaining good indoor air quality. Without control, it can even cause deterioration of joists and framing above the bathroom. ![]() In addition, long-term exposure to excess moisture and humidity can crack and peel paint and wallpaper, ruin wallboard, warp doors and rust cabinets and fixtures. During a bath or shower, humidity levels rise significantly creating the perfect breeding ground for mold, mildew and microorganisms that can negatively impact health. Maybe this helps, or maybe I’m providing advice where it’s not needed.Excess moisture has tremendous potential for damaging bathrooms. With the way you’re switching you could be waiting for a max of 5 mins for the fan to react, and that’s not ideal in a shower-room as you really want to be extracting the moisture as soon as the shower starts.īelow I have a shorter sample duration of 60 seconds and the gradient is 0.01666 meaning that I’m detecting a delta RH of 1% over 1 min (60 * 0.01667). If your sensors are only updating every 30 seconds, then that probably fine, but with my sensors I’m getting a sensor update every 15 seconds and I can use this to very rapidly detect a rise in RH and switch the fan as I found that it was less reliable with a larger sample duration. That gradient of 0.025 over 300 seconds equals an increase of 7.5% RH over 5 mins with a max sample size of the last 10 updates. That’s exactly how I’m doing it too, but if could I just make some comments on what I found with my sensors. The following is the 2-gang Zigbee switch module that I use to run the extractor fan at two speeds (it seems to work well with ZHA): .uk MoesGo Tuya Zigbee Smart Alexa 2 Gang Light Switch 1 Way or 2 Way Module, Timer.īuy MoesGo Tuya Zigbee Smart Alexa 2 Gang Light Switch 1 Way or 2 Way Module, Timer Wireless RF433 Remote Compatible with Smart Life Tuya Alexa Google Home(Only Work with Tuya Zigbee Hub, 2MQTT Available) : Switches & Dimmers : .uk ✓ Free. You can see how this operates on the card below: binary_sensor.bathroom_shower_occupancy Hi, I am detecting a spike in humidity from one of two Aqara Zigbee sensors to trigger a common extractor fan to run for a set period of time using a Zigbee switch module.Īutomation Config: alias: Extractor Fan Control ![]() I was thinking that I could then use an external humidistat sensor, which I could then place anywhere in the bathroom, which I could then use to trigger the fan. If so, can anyone recommend any relay in particular (I am in the UK, by the way)? If I bought a basic extractor fan (no timers, pull cords, humidistats etc.), is it simply a case of connecting the power cable to a zigbee relay and then connecting that to the extractor fan? I had my electrician wire it is in, so that the fan is not controlled by the light coming on/off and the fan has its own separate pull cord to turn the power on and off - the idea being that this pull cord should not, in fact, ever really be needed.Īs I use HA for a few other things, I though that adding smart control to the extractor fan is the way to go. ![]() I bought one with a built in humidistat but I just cannot get it to work properly - it stays on most of the time, despite the humidistat setting, and my guess is that the humidistat just is not particularly sophisticated (or even faulty). I am struggling to get my bathroom extractor fan to run properly. ![]()
