I did a few small automation for my car and the charger.

When I plug in the charger at home, it will check the current electricity prices and if below a certain threshold it will setup a plan to charge in those hours.

I also have a button I can press to make a plan depending on how many kwh I need as well as when I need it.

It will then automatically start and stop the charger based on these plans

For me, my favourites are definetely some light automations, namingly

• motion detectors and window sensors (where there aren’t insect nets) turning on and off the lights
• adaptive lighting automations setting brightness and shade based on the time

more than that

• turning down the (usually somewhat loud) music in the bathroom when I open the window to the street
• running the vaccuum when I’m not at home
• heating automations adapting to the weather report, presence, time and user preset

my future idea is to copy a nuki opener with an esp-32.

Here they are with links to the code

I have A LOT of automations. Some of my favorites are:

• Automatically set “house state” (morning, day, evening, night, not home, etc.") based on alarm state, time of day, last movement, etc - this state controls a lot of other automations
• Push message to my phone if outside camera detect a person when house state is “night” or “not home” (using Frigate for object detection)
• Automatically turn off lights at night or when not home. Automatically set lights to right level when home
• Push message when window has been open for more than 20 minutes.
• Push message if windows or doors are open when leaving the house or at night
• Push message with “morning update” and “evening update”. Including today’s weather, if I should sell some stocks as price has reached threshold, etc.

Basically, I no longer has to remember to turn on of off lights and if I forget something important in the house (such as an open window or turning on the alarm), it reminds me to do so (if it can’t do it itself)

I’ve got Emby tied into HA and it auto dims the lights on playback/pause if it’s dark with a toggle in HA to override.

A “night mode” button that starts my white noise MPD playlist in the bedroom and sets the speaker zone/volume, turns off all the lights/decorations, turns on one bulb in the living room overhead lights to 1% (just enough to navigate around furniture), and turns the bedroom lamps on to medium brightness with a 10 minute auto-off.

Overhead lights and lamps tied into a common dimmer and can select different modes (lamps only, overhead only, both, etc) and color temps. Overhead lights are set to be proportional to the lamps to keep the light levels even (unless overridden to “Chernobyl mode” which disables the overhead light limiter).

My “TV” is just a PC connected to a large dumb monitor upstairs and a projector downstairs. Wrote a MQTT agent in Python to control turning the screen on/off, volume, and other settings. This is to allow HA to turn the screen/projector on/off .

Have more, but those are the ones I’m using this moment.

A bunch of little things:

• when I hit the small button on my inovelli bedroom switch, it turns on my bedside tables, turns off all other lights, and closes my blinds
• when it sees my living room and bedroom tv’s on at the same time, it turns off my bedroom. My damn remote triggers both tv’s power when I’m in the living room
• flashing my kitchen lights if my deep freezer door is ajar
• opening my blinds in the morning automatically, and closing them at dusk.
• adaptive lighting with hue bulbs
