Simple light wake-up alarm with parabolic sunrise effect

Not sure about Apple, but at least on Android there is a Next Alarm that you can enable on the mobile app integration. You can probably create an input_datetime sensor from this using templates and use that as the trigger in the blueprint.

As for the switch, you can use the field for Workday Sensor. This was intended to be used with the Workday integration but it is really just a binary sensor. You could create your own binary_sensor template that is linked to an input_boolean you can manage yourself.

Thanks. Second option is what I ended up doing. Creating a switch helper and making a binary sensor template for it. The script and automation work great!

This should help you: https://www.reddit.com/r/homeassistant/comments/17fmyt8/comment/k6bdkgt/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

I’ve modified it so that it runs only when I’m connected to my local wifi.
And I copied it with a second trigger that it also sends the last known wakeup time to HA when I plug the charger in my phone.

Revamped original post to simplify the instructions and remove confusing/unrequired information.

Tried this out the other day, with my ikea rgbw bulbs this only uses the white leds which have too bright of a baseline, has anyone made a transition that incorporates the rgb leds to provide a more gradual transition?

Coleslaw1994 · January 28, 2025, 3:25am

I actually just integrated RGB into my adapted version for the same reason.

Would you consider adding pre- and post-actions as options? @steriku

Background:
I am using GitHub - basnijholt/adaptive-lighting: Adaptive Lighting custom component for Home Assistant which is somewhat interferring with your automation. Therefore I would like to disable AL for my bedroom light at the beginning of the automation and enable AL again once the automation is done.

steriku · March 6, 2025, 1:06pm

Sounds like it could be a nice feature. I won’t have any time to work on that for a couple weeks though. If you’re keen you can submit a PR to the github repo.

jeells102 · March 11, 2025, 10:48am

@steriku Hey! So I wanted to contribute and make some improvements and so I have just done my first PR and made a load of improvements. This is mainly to the automation YAML to make it easier, and add some extra functionality.

I added a person filter so that the alarm will only run when a person is home - useful for those who travel and don’t want their alarms going off when unnecessary.

I added some emojis to the descriptions and added some extra information and cleaned up the grammar too just to make it simpler and easier for those to use it.

I can work on Pre/post actions as well but just wanted to make sure my first PR was right, and that I’ve done everything correctly.

I’m not an engineer but work in Customer Support and so this is my first time doing something like this so any additional help would be great

steriku · March 17, 2025, 6:11pm

Hey @jeells102 I don’t see any PRs into my repo from you. Maybe you cloned or forked it to your own repo and made the PR there?

jeells102 · March 19, 2025, 10:35am

Hey @steriku

Apologies, I think I forked the repository but didn’t actually submit the pull request. Should be done now.

I’ve gotten close to working on pre and post actions but I’m not 100% there yet so that might need your input.

Thanks

steriku · March 19, 2025, 2:06pm

I’ve tested merged the PR. Thanks for the contribution! For the pre and post actions your working on, I found this that may help.

For anyone updating - this will break your automations until you edit them to include the person.

The link in the first post will point to the new version.

For anyone who doesn’t want the new functionality, you can re-import the previous version by clicking the link below

jeells102 · March 20, 2025, 4:59pm

@steriku I’ve just done another PR with pre and post actions, as well as a toggle whether to turn off the light at the end of the automation. Ready for your review.

chris400 · March 20, 2025, 11:46pm

Looks really great!
Would you mind adding some version numbering in the code @jeells102 ?

A changelog in the initial post would also be great!

PiManSam · March 25, 2025, 7:36pm

Thank you for your efforts, however it seems like this integration isn’t working as it should on my end. Specifically it seems to pulsate in brightness and I can’t set rules for the days where I want this automation to apply. EG, monday-friday at 7:30AM and on the weekend at 10AM. This has been the most frustrating automation I’ve dealt with in Home Assistant for YEARS now. Something that’s super simple to setup in something as terrible as the old Ikea Tradfri app, why does it have to be so convoluted here?

steriku · March 26, 2025, 12:35pm

Hi @PiManSam,

Thanks for your feedback. Unfortuantely it is impossible to have a single blueprint cater to everyone’s desires. There is nothing in the blueprint that would cause it to pulse so that may be some artifact that is an issue of how the bulb implements the brightness change or how HA sends the commands. I have heard of people having issues with Ikea bulbs and the transition argument for lights. I’ve been thinking of taking this out.

For your situation described above I’d say do the following:

Split the automation into 2 based on the blueprint.

Automation 1:

Workday intetration for Mon-Fri
Datetime helper for 7:30

Automation 2:

Workday integration for Sat-Sun
Datetime helper for 10:00

I’ve created a branch with a new version of the script that removes the transition argument. When you import this blueprint it should override your currently installed one and you can see if it fixes your pulsing issue. I’ll test it for a few days myself (however I don’t have an Ikea bulb) and if I don’t really notice a difference I’ll merge it into the main branch.

Merged this last change witht he removal of the transition field.

steriku · April 18, 2025, 4:41pm

Updated blueprint to include feature from @shbatm.

Extend start time entity filter to also allow datetime sensors
Add (optional) text offset for the time value to be able to start sooner. This also allows you to match a specific end time without having to manually do math to figure out the duration each time you change the Start Time.
Fix Selector minimum doesn’t allow setting timeout to 0 #7 and allow 0 for timeout.

Aasikki · April 19, 2025, 9:33am

Can the workday sensor be made optional? I prefer to wake up at the same time every single day due to adhd making me sensitive to any sleep cycle changes.

Also would be nice to have an option for minimum brightness, my wiz lights have a minor shortcoming where the actual minimum brightness is 10% for some reason (anything below 10% is the same brightness as 10%). Therefore with these lights it would make sense to start at 10% instead of 0%.

Big thanks for making this blueprint!

steriku · April 22, 2025, 2:19pm

New Release!!

Features

Workday is optional now. It can also use multiple binary sensors for this condition
Added optional pre and post actions
- post will only be executed if the automation is not stopped by turning the configured light off.
Added ability to set the starting brightness value. Default is 1.0 as it was before.
