When I received the PT2, those little LEDs/sensors in the back were constantly blinking, however, I haven’t seen them blink in about 2 weeks.
Is it a trick to save battery or are they broken?
I thought those SUPPOSED to blink in order to measure the heart rate.
Hey there! Do you have health tracking enabled? Can you send over a screenshot or picture of your health / hr settings?
Same problem here. Heart Rate only works using the Workout app. No live heart rate on any watchfaces.
HR should work fine on modern watchfaces e.g. Pebble Mesh. On old ones that weren’t recompiled it tends not to.
It should only activate every 10 minutes or while you’re actively tracking activities. If you think that that’s not working properly, could you submit a bug report in the Pebble app? Settings > phone > get help > new bug report
You can also just check the Health tab in the Pebble App - if it shows you historical data from the last hours it’s working as intended 
The HR sampling doesn’t take long, and if the watch sits snuggly on your arm then you can’t even see the green light except in full darkness.
