Smartwatch diagnostics

Test what the browser can see. Know when it cannot.

Use phone/browser-side connection and sensor context where possible, then use the watch maker's own diagnostics for battery, health sensors, charging and protected hardware.

Run these first

Relevant live checks

2
Compare native watch functions with companion app behavior
3
Use OEM diagnostics for charging/sensor failures

What DeviceOK/browser can help check
