I like a good smart watch and I appreciate open source, but an ESP32 isn't a great pick when low power consumption is important and the device is going to be communicating regularly. I'm surprised LILYGO went that direction in a watch form factor.
What would you suggest instead?
There are only a few features I care about in a smartwatch: 1. O2 monitoring. I have sleep apnea and live at high altitude, so this matters to me. 2. Motion sensor. Also mostly for tracking sleep. 3. Vibrator for notifications. 4. A screen backlight. 5. Battery life longer than a week. 6. Waterproof enough to survive a splash in the shower/rain. I consider GPS, cellular, AI, touchscreens, cloud-only sync and control…

an esp32 on an 1100mah battery will last years on deep sleep, and about a day with wifi on and in high power modes. a pixel watch 4 says they last 30 hours , ambiguously. they use a battery less than half the size. in reality with constant use they'll drop dead in 6 hours. the thing is clunky and heavy , anyway -- so if it lasts as long as an off the shelf watch who cares? also, the primary reason : lilygo shoves ESP…

Several Garmin watches last for weeks (24 days full charge, actual 1-2 weeks with heavy gps and fitness tracking), and I struggle to understand why consumers accept anything less. It seems like consumers don't realize what's available.
When can we finally buy a smartwatch that can keep its (color) display ON during the entire day?
September 18, 2020. That's when Apple released their Watch Series 6, which has an always on color display, and enough battery to last all day.
s/Watch/Smartwatch Regular DYI watches aren't big news... (I would be over the moon for a DIY smartwatch with zero AI and e-ink screen.)
I have one, its a bit bulkier than I'd thought it would be, but its a fine piece of timekeeping ..
This does look very cool. Every peripheral one could think of, even LoRA!
I really love the idea of LoRA in a watch though, so I hope that once this gets shipped, the software makes some leaps and bounds ..
Too bad it seems to not do health monitoring, my main use case of a watch now is sleep tracking with as long battery life as possible
