The best way to tell is to press the small button on your sensor once. You should see a green light flash slowly.
If you have a Diskus (circle shaped) or Respimat (tube shaped) sensor, you should hear a beep when you’ve pressed the button hard enough and then you’ll see the green light.
If you have a sensor for MDI - with blue button, you won’t hear a beep, but the sensor will still flash green. But if you have a sensor for MDI - with white button, you should hear a beep and see the light flash green.
If you see an orange/red light flash slowly, try waiting a minute and then press the small button again. You should see a green light flash slowly.
If your sensor does not light up, lights up orange/red consistently, or it doesn’t communicate with your app anymore, simply call our office at 877-251-5451 or email us at firstname.lastname@example.org. We can ship you a new sensor.
