I figured we could all share some of the cooler things we’ve done to get the conversation moving in here.
Here are some of the automations I’m proud of and get the most use out of.
Blinds and Lighting
- Open and close the blinds (Ikea Fyrtur) according to the light levels outside
- If a window is open, the blind will only close to 50%, but it will close automatically after the window is closed
- Turn all lights off when the blinds are opened, and turn lights on in occupied rooms when the blinds are closed
- Automatically close the blinds in the bedroom and bathroom when the shower is on. Open them after we leave the master suite.
Websites
- (Selenium) Auto login to Amazon to check on the status of my Kindle daily reading streak and notify me if I forget to read. We must keep the streak intact!
- Auto categorize new transactions in YouNeedABudget and mark them as approved, as well as pull my net worth into Home Assistant
- Get my most-listened to tracks and artists from Last.FM and pull those into Home Assistant
- Notify me if there are documents in my Paperless-NGx server that need to be categorized and filed
Reminders
- When I walk in the door, announce any outstanding Todoist tasks marked with the @alert label so I know to do it before I sit down. Examples are to change the furnace filter or Venmo my friend for Youtube TV
- I run OCR on the camera feed from my garage camera to determine whether the bins are in the garage. The bins say Trash and Recycling on top, so I look for those words in the image. If they are in the garage in the evening before trash day, I receive an alert
Media and Torrenting
- Notify me and display a badge in Home Assistant when there is a pending request in Overseerr
- (Selenium) Log into my favorite private torrent tracker website from Node-RED to check whether I need to take any actions
HVAC
- Preheat or pre-cool the house prior to peak electricity pricing going into effect. During peak hours, auto adjust the thermostat to prevent it from running
- Turn the thermostat off if there are windows open. Automatically restore previous setting (cool or heat) when all windows are closed.
- Turn the bathroom fan on after the shower is turned off and no one is around. Turn it off after 80 minutes or the humidity in the bathroom is within 10% of the humidity in the bedroom, whichever comes first.
Misc
- Node-RED monitors the status of my UPSes for my servers. If the battery drops below 50% while the power is out, it initiates graceful shutdowns of my Synology and other servers
- Auto sort the Home Assistant grocery list upon adding a new item

I’ve got a few fun ones:
At night, my cat sometimes gets the zoomies, so I have a projector pointed at a wall with a motion sensor. When he goes on his tear through the house while we’re sleeping, the projector turns on and plays a video of strings moving on the wall. This tires him out without him screaming at us to play with him. It turns off again after a few minutes with no motion.
The lights and Roku screens in my office are on a motion sensor, but are also linked with a seat sensor so they don’t turn off when I’m at my desk. Sitting at the desk also sends a Wake on LAN packet to my computer. Sitting at my electronics workbench changes the lights to bright white with another seat sensor.
Lights (HA), desktop wallpaper (with Wallpaper Engine), and in-computer RGB (using OpenRGB) change from blue/pink during the day to dark red/orange at sunset so being in my office late doesn’t mess with my sleep.
A macro button next to my keyboard disables my screens and turns on a fan pointed at my VR area for workouts.
Oh, and the button next to my bed that turns off all the lights in the house also turns off my PC.
Love the cat one! That’s a unique take on home automation that I have never encountered before.
Those are very original!
How do you detect the zoomies?!?
I just have a motion sensor in a hallway his zoom pattern follows. It’s not between the bedroom and the bathroom, so it would only trigger with the cat or a burglar (the automation is inactive during the day).
Oh, one more: My Google Home pings me and flashes the lights in my office if my washer/dryer are done, or if my calendar has an event in 3 minutes.
I have a couple of automations running, but my favourite is one of the simpler ones:
When I set an alarm on my phone all lights turn off except for a single night light (LEDs under my bed), and when I then put my phone down on the wireless charger near my bed (I only use that one wireless charger, so the automation just checks for any wireless charger), the light turns off completely and my phone screen turns off.
If I remove the phone from the charger before my alarm’s gone off, the night light turns back on, putting it back on the charger turns the night light back off, etc.
The automation does multiple useful things at once:
- I haven’t used a light switch at home in forever
- I haven’t forgotten to set an alarm in forever
- I get very obvious feedback that my phone starts charging
- I have a night light that’s easily turned on/off, without the need for motion sensors in the bedroom that could have false positives
- I have a clear trigger for when I’m in bed, that I’m using for example for my white noise machine that turns on for 45 minutes when I go to bed
This gave me the idea for how I can use a smart outlet to see if I’m using the wireless charger by my bedside table and not just any generic charger. Thanks!
Some great ideas there.
For me one of my favourites are my extractor fan control in my bathrooms. I have a switch on the fan and a humidity sensor close by. Turn on the shower and the extractor will turn on until the humidity is lowered enough, then switch off. In addition I have a static programmable button to press should you need it for other reasons. I just love the world of entities and how they link together to make something functional.
Yeah the humidistat in the bathroom is absolutely golden. The one I installed will automatically come on/off at a humidity set point or if I turn it on it will stay on for 15 minutes.
What I do Is I have a threshold. of switching on above say 75% and switching off below 70%. So it doesn’t have a set time. It’s just making sure things come down to at least 70% before it switches off. It does get more complex in winter as humidity tends to be higher by default, but I am playing around with the thresholds to figure out the optimal percentages. a fan on it’s own cant get the humidity down to below the general humidity in the area. Nonetheless. Fun to play with and works like a bomb.
For trash nights I just make sure the garage door is open and shut during appropriate hours and assume that I took the trash out. That’s never failed for me but if it was a problem I would probably just have the cameras alarm when I hit a certain zone and make sure that zone is triggered during a certain hour. Another option would be to put a Z-Wave switch in the garage by the trash cans I would tap whenever I took the trash out.
Auto relock the front door after 15 minutes, with a code lock so I can’t lock my keys inside.
Notification by telegram anytime any entry exit door is opened or closed.
Extra alarm if the doors left open for more than 30 minutes.
Alarm when the dogs GPS collar gets to less than 20%, notification when the collar gets above 80%.
Blue Iris sends a picture to telegram whenever there’s motion on my cameras during certain times of the day or night.
Front doorbell AI notif on person even if they don’t ring the bell.
Automated sprinklers based on the weather using beehive and HA automation.
I’ve been meaning to do that as well. I only have the fan automated in one bathroom, but I’d like to automate all of them to have them automatically turn off after running for 20 mins or so.
The ones I use the most are:
- Turning on lights and setting specific scenes when I turn on TVs in my bedroom, living room and theater room.
- Brighten lights whenever Plex is paused or finishes playing, which is great in a dedicated home theater where the lighting is very dark when watching a movie. This has actually helped improve many hang out nights with friends because the moment after a movie finishes is less awkward, leading more naturally into a nice conversation before every heads home.
- Reminder notifications for when washing machine or dryer cycles finish, or when my garage door has been open for more than 15 minutes (unless I override that with a toggle on my dashboard).
- Turning off all of my lights and switches when I leave the house, unless a boolean variable is flipped (e.g. if someone else is at my house w/o me, which is unusual since I live alone). Well, not quite everything, there are a few devices like a couple power monitoring smart pugs that always remain on.
My Air Quality monitoring. I monitoring CO2, VOCs, PM and such. I then have automations run the air exchanger. They say air inside is 5X more polluted then outside I have the opposite.
That’s pretty cool! I haven’t dove into the world of air purifiers yet.
Honestly it was easier than I expected. I have a fairly new home and it has an HRV. I replaced it’s paper filters with MERV 8. I also picked up an Air Gradient, slick little project.
I change my filters about everything 3 months, they get pretty gnarly. I filter the air on the way out with a basic screen because it passes over the blower and…by design it would get absolutely filthy in short order.
I made a bunch of “sensors” in HA to calculate the indoor AQI, and average.
Cheers.
What indoor air quality sensor do you have?

Air Gradient. I bought their DIY kit.
Cheers, Henry.
I’ve been using Home Assistant for a while but I don’t have a ton of IoT devices so I don’t have a ton of automations set up.
My most useful though is an alert that triggers when my garage door has been open for ten minutes, and then again every ten minutes after until it has been open for an hour when it will automatically close.
Accidentally left the garage door open all night at least twice before this and thankfully nothing happened but the automation has prevented this at least twice as well.
Also gives me peace of mind in case I accidentally open it when I’m away.
@Toribor @ilikedatsyuk Same!
Some hacked together sharp ir sensors have worked way better than I expected.
https://github.com/DerekParks/GarageDoorIRSensorI built out this GarHAge setup which uses magnetic reed switches for state detection. I’ve considered that a reed switch getting bumped might get it stuck in a loop of endlessly opening and closing though and tried to care for that possibility in my automations.
Really I just need to get an IP camera for piece of mind when I’m traveling. Even if the state detection is broken I can ensure that it’s closed and disable the automation until I can repair it.
A few automations are running in my house:
- Turned the nightstand light into a wake-up light, which distinguishes between weekdays and weekends,
- Kitchen light turns on and off based on sunset and midnight with random offset respectively,
- Garbage collection notifications,
- Introduced an extra (wireless) light switch in the hallway, which controls a Shelly connected to the light. The original light switch is still intact, however it is positioned at an unconvenient location.
In the coming period I want to:
- Automate the shutters and combine that with a light sensor.
- Introduce a routine that starts the washing machine and/or drying during the day based on the amount of incoming solar power. Not sure yet how to do this, since the washing machine has a physical start button via touch.
IDK if taking the machine apart is an option, but I once integrated a machine with touch switches with an arduino by probing the board with an oscilloscope and finding the signal that was triggered when it was pressed. It wasn’t as involved as it sounds.
I like that this method integrates everything in the machine itself. Not sure if I’m confident opening the machine myself, but I will definitely keep this option in mind. Thanks!
How does your wake-up light behavior change on weekdays versus weekends?
For your washing machine and dryer, could Switchbot be a good fit?
How does your wake-up light behavior change on weekdays versus weekends?
The current automation works via Node-RED, where a function will check the current day. If that day is saturday or sunday, the wake-up light will not be enabled. The automation is documented here.
For your washing machine and dryer, could Switchbot be a good fit?
Thank you for the tip! The buttons are touch switches, so maybe wrapping the Switchbot’s probe in something conductive might work?
That’s awesome – thanks for the documentation! I really like how your website is set up as well.
It looks like at least one person has modified the Switchbot to work with capacitive touch buttons.
Not my website, but I’ll let the owner know!

That looks promising. I will check it out and possibly post here when it’s working.
I’m tracking my HVAC filter and rest it’s 90days with an NFC tag
Loosely followed an online how-to to create a tracking chore list using NFC tags for my son’s allowance. Automations to nag him on trash night to gather/take out the trash.
A simple Automation that turns on a fan in the basement when the outside temp is above out AC setting to help distribute cool basement air.
Outside security lights on/off at dusk/dawn
House auto arms/disarms (Alarmo) when everyone leaves or someone arrives (via life 360 integration)
On trash day, after noon if my son scans (NFC) one of the trash cans, the garage door opens to let him in/put them away.
My son gets a notification when he comes home from school if we got mail (aka the mailbox was opened that day)
Those are the ones I can think of off the top of my head.
I’m using HA to track device usage of my kids, and I can give them bonus time if they do something nice or a chore. And, negative time when they misbehave. Perhaps an idea for you?
What are you using to track/control the screentime?
Yeah that’s quite complicated as e.g. Family Link (which we use on their Android devices) doesn’t have an API.
- Input boolean per child “Device in use”
- platform_history sensor to track how long it was on in a week.
- I’ve installed the Home Assistant app on their devices, whenever it turns on for more than a minute, it turns on the boolean input.
- They also play on the xbox together during the day. Whenever the xbox turns on, and they log out my account, it also triggers an automation to turn on both switches.
- Input helper with weekly device limit (time)
- template sensors that calculate the time left
- Switch can be manually turned on/off via our Home Assistant tablet in the living room, which also displays the remaining time etc.
It’s very custom and sometimes buggy, e.g. this morning the xbox sensor suddenly become “On” despite the xbox being turned off. So I’ve also added some custom helpers to be able to decrease/increase the usage for that week if something had gone bonkers.
I’m impressed, my best I feel is to turn on the outside fans when a person is detected and the temp is over 86 (I don’t know why I picked 86, seemed appropriate at the time)
I have some arbitrary temps in my system too. I also have our bed warmer automated to turn on each night, but only if it’s <=60 F outside.
Oh, that’s a good one
I love my door sensor announcements. Garage opens? Google Home goes “GARAGE OPEN”. Front door blows open at 11pm because it wasn’t closed properly? “FRONT DOOR OPEN… all home lights come on”
Just security stuff. So much customization that other products don’t offer.
My tankless hot water heater is controlled via Home Assistant too. Shuts off the circulation loop at 11pm~630am. Saves a ton of gas!
I have my house switch to night mode after a certain amount of time after sunset. During night mode:
- turning my computer on or off will toggle my desk light.
- if my cellphone is put over my wireless charger it will turn off my bed light (or turn it back on if I remove it).
Absolutely loving the Leaving home automation: Turn off all sockets, lights, set up intruder alarm, start simulating occupancy on random times. And vice versa when I come home but lights adjusted to light/weather/daytime conditions No-brainer and utmost convenient.
Some more automations:
- Start movie: change sound source amplifier, adjust volume, turns off all other music sources and lights in the apartment, turn off motion sensor living room, dimm lights depending on light sensor/daytime and enjoy
- Add to playlist: notify to m3u file, check m3u file for duplicates via shell script, amend file location of each line in m3u file and transfer to other server instance
- “Siri good night” triggers all lights off + TV. Upon iOS event trigger and all lights/TV off, run Kodi library update/clean up, CHMOD movie file location and shut down server, turn off unnecessary sockets, switch to night mode (only specific motion sensors react and turn on low level light)
Washing machine and dryer are monitored for power consumption. When the power consumption drops to a minimum for some minutes then my wife gets a push notification to her mobile that the machine has finished. Was a bit trial & error especially for the washing machine which has phases while washing where it does “nothing” for some minutes and at the end it turns the laundry every now and then after the program is done (to avoid crease).
Same here. It took some trial and error, but it’s awesome to have the current laundry status in Home Assistant.
Even I, a lover of all smart home gadgets, don’t want my laundry machines to have any smarts built in. I just want reliability; I can add the smarts myself.

Turning on heated blankets at night, turn off after I plug in my phone to charge.
Climate control in every room.
Made dumb standing desk is now smart and goes up and down randomly every 45-60 minutes while I’m working.
