Pixel Watch 2 - Privacy Preserving Setup

I've been trying everything i could think of to make the watch work under GrapheneOS - Here is what i learned:

• Unpairing the Watch means factory resetting it.
• Every feature (literally everything) is google dependent (who would have thought.. i know)
• Pairing with your phone requires the "Pixel Watch" -App to be installed on your main profile (not work, not private space) alongside Google Play Services. There's no way around.

This is obviously unacceptable. So i did a bit of research and found a way that will not only be way more practical, it will also be private.

First i created a second user on my Phone, installed Google Play Services and the pixel watch app on it, logged in with a newly created google account and completed the setup.

I know some people use a chinese version of the WearOS app to bypass the google login. Since i don't want a chinese app to configure my watch, i didn't even try that.

After the watch was set up, i continued and:

• Deleted the user profile from which i connected the Watch
• Enabled wireless debugging
• Debloated the watch as good as possible (i will have to root the watch in the future to properly do it)
• Removed the Google account in the settings
• Cleared all Bluetooth preferences
• Enabled Bluetooth discovery
• Installed KDE Connect on it (not meant for WearOS but it does work barely)

The watch is now in a state where i can use it daily.

But i also want to make use of all those fancy quality-of-life features, like heartrate monitoring, sleep tracking and so on.

Now comes the fun part.

I've created a basic Kotlin project with both a mobile and WearOS app.

I will implement features like:

• Notification sync
• Call notifications
• Media Player Control
• Weather (openweathermap)
• Heartrate monitoring
• Sleep tracking
• Do not Distrurb Sync
• Homelab integrations (Nextcloud, Immich, Uptime Kuma, ..)
• And much more ..

The goal is to keep the watch offline, let the phone do the heavy lifting and communicate with a selfhosted database. I may even add a frontend and an API so people can integrate it for their needs.

Sounds good but why don't you just buy an #opensource #smartwatch like the #pinetime - You may ask.

Because as much as i hate to admit it, i love the design, the look and feel of the pixel watch. And i'm sure that i'm not the only one.

I also bought this one cheap for around 120€ #refurbished. So the value i can get out of it seems pretty good to me.

So much for today. I haven't even started tackling the Bluetooth connection yet 😅. Let's see how that turns out

I have added a poll to this post to see how many people would be interested in a setup like this. Please let me know if you have any suggestions, ideas or expertise in that regard.

Cheers.

Task for this evening is to root my 'old' Android Tablet and trying to install some linux distro ... 🤓

Zimperium found a critical flaw in an older version of the Android rooting tool, #KernelSU, that could allow a full device takeover. Update now if you use it!

@ljs @ohjames AFAICT #Android for the most part doesn't do much of an #init system and merely uses #toybox to make it's #UI able to run and completely abstract the underlying system.

• And even if it were to run it, without #rooting AND extensive knowledge of #Linux most people won't even be able to do so.

Plus yeeting the init system - even if it's just a single /etc/init file will brick the system and necessitates reflashingbabnew ROM.

• In theory one could migrate fron one init system to another but explaining that will exceed my 11.000 character limit and makes even less sense.

Alright, this week I'll get my old Samsung a52s back. What should I do?

#android #rooting #samsunggalaxy #lineageos

I was today years old when I started #rooting androids.

Lessons so far.
1. Root your phone before it goes stale. Tried to root a 11 yo HTC. The Tools and boot images are memory holed.

2. #OPPO cockblocks rooting (at least on CPH1941 😥)
