Open source smart watches
Open source smart watches
If you were to buy an open source smart watch today to pair to a GrapheneOS smart phone which would you choose?

pinetime is a neat affordable project to check out... but i think they're sold out atm. i saw someone say that in the last week in the chatroom
-
Got PineTime pre-tariffs (even though it took a while to ship to US)
Pretty neat piece of hardware, has everything that I want (notifications, time, weather, timer), InfiniTime OS is open source and was easy to read, build and flash (had to do so to add missing Cyrillic letters and a shortcut)
As long as your expectations are that of a microcontroller-powered device and not a supercomputer-on-your-wrist, it's fantastic.
-
Pine was my first stop but when I went to purchase I got a 404/so I assumed it was not available which is why I'm here
-
In the EU store it is currently out of stock and also priced at 66€. Can it be, that this is a victim of the US-EU trade war, that Trump started?

Commenting because no-one mentioned the Watchy
-
Potentially relevant for anyone considering a Watchy

-
Watchy, while a cool product, is an eink watch with no smart features.
-
There's an Android app with firmware for the watch that supports notifications, so the watch has the potential for smart features
But it looks like there's no equivalent app for Graphene OS, so in effect, you're right, no smart features
-
What exactly is meant by "smart features" ? The watch is an esp32 microcontroller driving an ePaper screen and a gyroscope (I forget if there are any other peripherals). It's already much smarter than a "regular" wristwatch, and being open source you can make it as smart as you want (in theory and within the performance allowed by it's specs, of course). The stock "os" will fetch the weather and adjust to daylight savings via internet.
Do you mean stuff like there's no smartphone app available for it? It doesn't pair with a smartphone out-of-the-box to do things like show SMS, email, calendar events, etc?
-
Very true but you can dual wield that watch with an actual full-blown open source smart watch when the full one becomes a thing

You should check out gadget bridge. It's got a list of devices it's compatible with.
-
Link: https://gadgetbridge.org/gadgets/wearables/
Look for 'Highly Supported' and the unlocked-padlock-icon.

I just pulled my Bangle.js 2 back out to play with making a better reminder system for myself. It works better than any of the other open source watches I've had with my GrapheneOS phone. The hardware isn't open source as far as I know, but their mobile app (fork of gadget bridge) is, as are all the apps that run on the watch, and (I think?) the watch OS.
-
use gadget bridge for which ever you get.
-
https://asteroidos.org/ not great device support but its a option
-
I'm happy enough with my current (non-oss) watch that I'm not going to change until it becomes unusable, but if I had to make the decision today, I'd probably have a go at installing Asteroid OS on a secondhand device.
-
Thats probably the right direction to go, they support some styles that I can get behind like the LG watch 7 its in the same genre of my OG Apple watch Ultra
-
-
I'm currently also at that point, trying to decide what to buy.
Does anyone have a good recommendation for a smart watch with good compatibility with gadgetbridge? I'm not sure where to look (gadgetbridges list is long).
Something with a color display, maybe a week of battery life, being able to show my notifications and configuration without needing the manufacturers app
-
I'm currently using the Nothing CMF Pro 2.
You configure it with the proprietary app to get the initial paring key, then you can switch to Gadgetbridge and disable or even remove the Nothing app.
The Good: cheap device cost, nice UI elements, machined aluminum bezel looks premium. Push notifications and most features work.
The Bad: semi-annoying workaround to get it set up initially, not all features work, not using the proprietary app disables using the Nothing watch face library so you're stuck choosing from the 5 or 6 default designs that come with the watch.

Amazfit active 2

That one looks good. Though it seems the process to get the pairing key from the proriatary app on a non-rooted phone is currently broken. My phone is currently not rooted. Don't know, how that works with rooting on e/OS. If I can root it, get the key and then remove root without wiping the phone, then I might do that.

Currently using amazfit trex2 with gadget bridge.
All the things I actually use work. My only peeve is that you can't silence /stop phone alarms from the watch, but I believe this is a general android thing...
-
Thanks for mentioning Gadgetbridge. I finally checked it out. It is surprising that it supports other devices besides smartwatches.
-
-
I was looking at https://open-smartwatch.github.io/gallery/gallery-main/ recently with some intrigue, if I had a 3d printer I'd consider building it
-
Look for makerspaces near you or even just look for printing services like craftcloud or shapeways.

Isn't the pebble watch getting a re-release? Might be neat to tinker with. There's also a conversion kit thing for one of the classic digital casio watches. Both are tinkering friendly and open source.
100% Pebble
https://store.repebble.com/
These projects are fun to hear abt because I always go "damn I wish I heard about that six years ago" only to find out it is emerging from 8 years of developmental purgatory. So in a way I got to skip the wait
My pebble 2 Duo arrived yesterday... It doesn't yet pair with Gadgetbridge but I imagine it will at some point.
I've also ordered the Pebble Time 2, which I think will be a better watch for me: going back to a b/w display without touchscreen is hard. The Time2 has both colour and touchscreen....
I went with the duo, haven't gotten mine yet. Considering I've never given up on my Pebble 2 and Steel (with 1 day battery life) it's an easy switch for me. I tried the new Pebble app, it sucks. I'm hoping the Rebble version will work with the Duo. I use waaaay too many third party software options to go without.
I was wondering this myself. Thank you for that useful information.
