how to create a wakeup light? [Iphone]

---

After installing Pimatic, one of the ideas that came to mind was to create a wake-up light. It needs to do the following:

• Control a KaKu dimmer to gradually turn on the light 30 mins before the alarm goes off.

It needs to work according to the following conditions:

• easy to work with
• Use alarm on an iphone without jailbreak
• If working with an 3th party app it should run in background.

Bonus points:
It would be awesome if the alarm app is able to put the phone in flightmode or at least turn off the airplane mode let’s say 40min before the alarm time in order to start communication with my Pimatic Pi. If not possible i’ll leave wifi on all night.

Concept approach:
As far as i know it’s not possible to retrieve the stock Iphone alarm app time and send it to pimatic. Best workaround I’ve found is the sleep cycle app which has the ability to work with Philips Hue.

I found a tool which is able to simulate a Philips Hue bridge:
https://github.com/armzilla/amazon-echo-ha-bridge

If the Pi can run this, their should be a possibility let the Iphone communicate with the Hue bridge simulator and the Simulator communicate with the Pimatic Hue plugin and control the KaKu dimmer.

As i’m not quite experienced i was hoping that someone is able to help me set it up like this or maybe knows a better / other approach.

Well, I’m not fan of using kaku for a wake up light. because they have only 15 dim levels, so it won’t look smooth. And if it would have like 100, you will flood the air with 433mhz data.

Philips hue works totally different. It sends 1 message to the light itself with the requested dim level and the fade time. The light itself will do the rest. Hue also has 256 dim levels, so very smooth.

You can use this rules for transition time.
For 3th party app You can use pimatic-shell-execute plugin.
But I do not know how with iphone. I have Android phone.

Thank you both very much for your input.
I wasn’t aware of the few dimlevels and flooding the air with 433mhz data but it makes a lot of sense now i read it. I will start thinking about an alternative for more smooth fading and break this project in a few steps.

Step 1, how can i catch the alarm time from my iphone?
This alarmtime needs to be set as trigger for the start of the day and can be used for multiple purposes like wakeup light, starting the coffee machine etc. To let this work i assume we have to work with a 3th party app that retrieves the time from the stock iphone app and send it to Pimatic OR a 3th party alarm app which can send the time.

Since the sleepcycle app has the ability to work with Philips Hue I still think this might be an easy opening to receive the alarm time trigger as long as we can fool the app to see the Raspberry Pi as Hue bridge. (for this we don’t need to control anything Hue related, only use this input as trigger for an other script.

Any suggestions?

What guide your WAKE UP with Pimatic. Equally apply to everything else (lights, coffee maker etc.). And let your phone just like an ordinary alarm device.

Shortly I do with this program, with using the MQTT module, is finally able Pimatic call me over Asterisk, for example.
It has support for Apple Push Notification Service.

I plan to use it to handle all the alarm from Pimatic.

P.S. I wake up in the morning with music from Kodi.

P.P.S Just the idea because I solve something else.
