I do have a feature request: optional Window Sensor + Push Notifcation
My flat is very well sealed, so when I run the bath fan I get a tiny bit of negative pressure and I hear a faint whining noise from the windows.
Would it be possible to link one or more windows sensors with the blueprint to check if a windows is open and if not send a push notification to my phone as a reminder to open a window?
Generally it would be nice to get a push notification when the fan turns on and off.
As @sparkydave suggested it would better to use another automation for this. This blueprint is very complex and to add a feature like this would make it even more complex.
The good news is I already have another blueprint that will do this and it is called State Notifications & Actions. Your trigger would be when the fan turns ON (in the start trigger). Then in the start notify add your device. In the Global conditions add a condition for entity, state, add your window sensor with the state OFF or closed.
Now when the fan turn ON and your window is closed you will be notified.
You also have so many more options in this blueprint like actions. You could also use the actions so your lights flash ON and OFF say 3 times if the window is closed. You can use notify and actions or rather than send the notification you just use the actions so whoever is taking a shower can just see this visual.
I have an automation setup like this, I use a humidity sensor in the bathroom and another that is on the landing to create a delta that the automation uses to compensate for the seasonal climate changes so it knows the normal humidity of the rest of the house. Great work!
Hi @Blacky! Quick question...is there a way to set like a 'minimum value'?
I.e. my bathroom can get up to 90% sometimes while showering, but once done, the fan very quickly brings it back down to normal. But the blueprint is typically turning the fan off when the room gets around 70-75% because the derivative value is hit, which doesn't seem like an ideal humidity level. Esp since 5-10 more mins of the fan running brings it down to 55-60.
Is there a way for the blueprint to not turn the fan off until it at least hits a safety minimum (like 65%, 70%, etc.)? Sorry if this is an existing setting and i missed it. Thanks!
Have you adjusted your Time Delay in Summer mode and also in winter mode if you are using winter mode? Default is set to 10 min so you may want to increase this to 15 to 20 min as you suggested this would bring down the humidity for you.
I didn't use a turn OFF humidity % as throughout the year (even the day) this can change.
Just a heads up if some of you are using my code for your Atom Lite ESP device. I have updated the code click here. The board framework changed from Arduino to ESP-IDF.
PS: I also plugged the Atom Lite directly into the host running HA did a clean build and then uploaded using Plugged into your Home Assistant server option.
Hi Blacky, a value % the sensor has to reach until the fan goes off would be a nice feature. Our bathroom Fan sometimes needs 2h or 3h to get the room to 60%. (like Hygrostat helper does). The delay is not a solution here.
Thank you for everything.
What you could do first is change your Falling Humidity Derivative to -30. Now the automation will not turn it OFF until the Safeguard - Maximum Run Time. So maybe change this to 3h or 180 min. Then just create a basic automation to turn the fan OFF when it drops below 60%. Test this all out see if it works.
Hi Blacky, this is a really cool blueprint thanks and my wife loves it which is always a sign of a good automation.
I do have a question, we have two humidity sensors in our bathroom. One over the shower and the other over the bath, but only one inline fan that I would like to trigger from either of these sensors rising above. Whats the best way to achieve this with your automation?
