# Gadgetbridge compatible Smartwatch with good sleep and health tracking? **URL:** https://discuss.privacyguides.net/t/gadgetbridge-compatible-smartwatch-with-good-sleep-and-health-tracking/32737 **Category:** Questions **Created:** 2025-11-11T19:36:23Z **Posts:** 49 ## Post 1 by @Davian — 2025-11-11T19:36:23Z Hello, I am looking quite a while for a smartwatch that is compatible with Gadgetbridge and also has good sleep and health tracking from which the data gets correctly transfered to Gadgetbridge. Can someone recommend me something please? --- ## Post 2 by @anon39279085 — 2025-11-11T19:39:26Z question how much of a tinkerer are you from none to “I am a tinkerer” --- ## Post 3 by @KevPham — 2025-11-11T19:45:30Z > [@Davian](#): > > I am looking quite a while for a smartwatch that is compatible with Gadgetbridge and also has good sleep and health tracking from which the data gets correctly transfered to Gadgetbridge. You may want to look at [Amazfit](https://gadgetbridge.org/gadgets/wearables/amazfit/) as most watches on that page are highly supported, --- ## Post 4 by @anon39279085 — 2025-11-11T19:47:24Z there’s (mostly) 2 catches which is why is best we wait for OP to answer first. --- ## Post 5 by @kissu — 2025-11-11T20:17:17Z I pre-ordered a [Pebble Watch](https://store.repebble.com/). I do love the fact that it can last an entire month, have the bare minimum, relaxing E-ink screen and is embraced by an apparently lovely community passionate about FOSS. Also fully compatible with [Gadgetbridge from day one](https://gadgetbridge.org/gadgets/wearables/pebble/). :star_struck: The CEO also looks kind and apparently cares about real things (no AI salesman or whatever). It might flop. Will not be as refined as an Apple Watch Ultra but hey, I do value some points over others more. Would be a perfect match for GOS and some basic healthy metrics IMO. :+1:t2: PS: you can hack the hell out of it and have something playful and fun. Gosh that one is a thing most company are loosing nowadays. Besides that, Garmin maybe? Their support on Gadgetbridge looks subpar and their software as a whole is not the best from what I saw. But, it’s some kind of well known brand if you also need to have something a bit more rugged. :hugs: PS2: Pine or Bangle also look like decent solutions. --- ## Post 6 by @anon39279085 — 2025-11-11T20:21:07Z I mean the CEO actually was the one who founded Pebble before it went on a rollercoaster then somehow just came back like as if somehow the sunk titanic was revived. The question remains as Gadgetbridge isnt necessarily one click ready to go on all watches --- ## Post 7 by @Script1743 — 2025-11-11T20:21:26Z I’m currently considering buying the Amazfit Helio band. It’s sleep and fitness tracking is top tier. It uses Zepp OS, which should have good compatibility with Gadgetbridge. If not, I will just use Zepp app without network permission. I kind of like the idea of wearing a band on your biceps, because this allows you to wear a classic watch on your wrist, while also tracking your stats. But if that is not your cup of tea, I’m sure Amazfit has some great watches to offer. My current one is an Amazfit Bip, I have been using it for 6 years and it has amazing compatibility with the open-source Gadgetbridge app. --- ## Post 8 by @kissu — 2025-11-11T20:24:32Z I think that thanks to the community it might not be that hard to flash even if you’re not super tech savvy. Seeing how easy it is to flash GOS on a Pixel, I think that a single YT video with a QR code in the box is all you might need for a working Pebble. Also, privacy will always have more friction that your go-to proprietary device. :sweat_smile: But yes, also depends if you want: - just bare metrics of heart rate, sleep tracking etc - a smartwatch that does a bit more --- ## Post 9 by @User53 — 2025-11-11T20:50:45Z > [@Davian](#): > > Can someone recommend me something please?

I’ve never had any sync issues and it always reconnects to my pixel 7a with GrapheneOS. I will say that I never installed or connected it to the official Garmin app, I connected and used it entirely through Gadgetbridge. --- ## Post 13 by @Davian — 2025-11-13T19:15:02Z > [@anon39279085](#): > > question how much of a tinkerer are you from none to “I am a tinkerer” I think I am not so much of a tinkerer.

I can’t confirm myself, but they are usually listed on the website as the most supported brand besides pebble, which has an open–source OS and will soon release two new models with anticipated day 1 support. --- ## Post 16 by @KevPham — 2025-11-13T20:35:38Z 3 posts were merged into an existing topic: [The new Pebble app is live on iOS and Android](/t/the-new-pebble-app-is-live-on-ios-and-android/32816/2) --- ## Post 17 by @Davian — 2025-11-14T18:41:06Z > [@anon39279085](#): > > The :locked: icon indicates you requiring to use the OEM app, likely also needing to sign in (especially common with Zepp OS and Xiaomi) > > The :unlocked: icon means you can use the watch with gadgetbridge without needing the OEM App. Does the lock mean that I need the app on time or all the time? --- ## Post 18 by @unseen — 2025-11-14T18:46:23Z I have an Amazfit but I don’t want to root my phone at the moment, so unfortunately I couldn’t use it with GadgetBridge.

See more information in [huami-token#118](https://codeberg.org/argrento/huami-token/issues/118).

For me Garmin Connect (the official Garmin app) won’t start without internet connection.However the garmin app is great for sleep and health tracking. O’ve only briefly tried gadget bridge and didn’t liked it. The sleeping time was also different in the gadget bridge app than on my watch itself. The watch also stores the sleep data, so when I wake up I’m using the watch to look up last nights sleep. According to this person Gadget bridge shows different sleep values then the official app. The official app is also not an option from a privacy standpoint because its requirring network permission --- ## Post 39 by @kissu — 2025-11-29T12:22:49Z > [@Davian](#): > > ChatGPT says I would always take this with a grain of salt given that it’s probably sourcing that from potential marketing or obsolete reddit sources.

Yes, but I don’t see why the Venu 3 should have an unfair advantage over other Garmin watches in terms of marketing strength or reddit posts. And after trying to digging through so much information myself, I thought that it would also be good to ask AI for help in digesting the information. Interestingly it also takes this thread as a source --- ## Post 41 by @kissu — 2025-11-30T19:45:38Z > [@Davian](#): > > Interestingly it also takes this thread as a source That’s precisely the issue, the amount of reviews. There is a YT channel that is specialized into health metrics on wearables, not sure if that guy made a video on the Venu 3. But besides this, having 10 people saying the metrics are good is not a big enough amount of people. 10 reviews with 5 stars total score has quite less value than 3000 reviews with 4.5 stars total IMO. --- ## Post 42 by @Davian — 2025-11-30T21:24:53Z > [@Davian](#): > > Thanks to everyone replying to this thread :slight_smile: > > I think I will to buy a Garmin watch, and I think I will go with the Garmin Venu 3 for the following reasons: [@moderators](/groups/moderators) Please unflag my post.

Does the Venu 3 has so much less review then the Instict , the vivoactive 6 or something different matching my requirements? --- ## Post 44 by @kissu — 2025-12-01T09:46:52Z I don’t personally know, have made any research on Garmin myself.

I am the only person who wants a button to view flagged posts to see what was inside? --- ## Post 46 by @Davian — 2025-12-04T21:34:58Z How do I update the firmware of a Garmin watch? I tried these things: ### Gadgetbridge file loader Gadgetbridge offers the option to flash firmware from file, but doesn’t provide any way to obtain this files. I tried to find a firmware file for my watch on the internet, but didn’t succeed. ### On watch Menu Deep in the watch setting there is an option to trigger an update with the watch: Hold Lower button \> Settings \> System \> Software Update Then there are two options: Add Network Use Bluetooh I don’t want to add a network because this would allow the watch to have a direct network connection and therefore exchange data in an uncontrolled way. So I tried to use Bluetooth, but despite my watch being connected to my phone over Bluetooth and the Garmin connect app being open, it jsut searched and then failed. ### Garmin Connect App I tried to find an update option inside the official Garmin connect app, but it seems like there is no such option. But I am not sure because the app is very confusing and lacks a search function --- ## Post 47 by @Davian — 2025-12-05T17:23:47Z ### Garmin Express To update the firmware off the watch I needed to start a windows pc, cause the Garmin Express .exe doesn’t run with Bottles. After I installed Garmin express on Windows and connected the watch it first stated that it was up to date, I repeatedly searched for updates and after approximately 10 minutes the watch was suddenly installing an update, which was only visible on the watch screen and not in Garmin Express. . I really don’t get why the update process is so stupid and buggy for Garmin watches and why Gadgetbridge can’t provide links to obtain firmware files to just flash them with GB. --- ## Post 48 by @SunDevil311 — 2025-12-06T23:13:32Z I’m actually looking into this as well. From what I’ve read, and based on the GadgetBridge website, I’d recommend an AmazFit device. Personally, I plan on trying the Band 7. The vast majority of Zepp OS devices appear to have good support, but it varies model-by-model. Here’s the reference for AmazFit: > **[Amazfit - Gadgetbridge](https://gadgetbridge.org/gadgets/wearables/amazfit/)** > > A free and open source Android application for bluetooth devices. There seems to be some confusion about obtaining the auth key. My understanding is that the newer AmazFit devices–based on Zepp OS–can simply pull the auth key from either a third party app called Notify (link below) or the official Zepp app with huafetcher. > > > Heart and activities tracker, notifications, maps, button actions and more tool... The difference is that you can supposedly firewall Notify, generate the auth key, then uninstall. With the Zepp app you’ll have to create an account and use either hua-fetcher or huami-token utility to extract the key, though this should be avoidable by using Notify. Neither root nor ADB should be necessary if you go the Notify route. Again, this is my understanding of how the newer Zepp OS-based devices work, based on my own research. I haven’t actually set it up yet, though I do plan on purchasing a Band 7 shortly for this purpose. I’d love to hear from any AmazFit owners who have actually gone through this process with GadgetBridge, in order to confirm I’m not mistaken. --- ## Post 49 by @Davian — 2025-12-17T18:15:14Z I want to share some of my experience since I have the Garmin Venu 3 for about 2 weeks now. ## Health Data Tracking The Garmin Venu 3 tracks my sleep and also share’s this data with the Gadgetbridge app, but there are some major issues: ### Incoherent Data between watch and app Every time when I checked it, there was a data difference of sometimes even more then 2 hours between the sleep time data in the Gadgegtbridge app the data on the Garmin watch display. Example: Sleep time on watch: 7h 51m Sleep time in Gadgetbridge: 5h 45m Other data like the sleep score is syncing without issues. ### Interruption of Sleep If I’m getting up at night to go to the toilet and its takes a little bit longer, then Garmin registers this as having risen up and restart’s the sleep tracking when I’m going back into bed. If I am waken up for toilet 3 hours before my normal wake up time, it says that I have only sleept 3 hours when I finally wake up. This leads extreme bad sleep ratings.
