Control elements electronics Sensotronic 2.0.0 and higher

(A) Function and Reset buttons:

Using a SIM card tool supplied with the testkit (see illustration on the bottom) or a standard toothpick, you can actuate these buttons:

  • The Function button (bigger hole, left) causes the device to "sleep" (save battery but also turn off Bluetooth and all other functionality like measuring data or recording). When it's pressed, the red LED lights up:
    • Keep the button pressed until red LED stops being lit (ca. 3 seconds). Then, let go of the button, to set it to "sleep". If you keep pressing the button, the electronics will start again.
    • To wake-up the device afterward, press the button again until the blue LED starts blinking again.
For dispatches before 13.11.2023 / Before firmware version 3.0.0

Keep the button pressed for longer than 3 seconds. Then, the red LED will light up and you can release the button. After about 2 seconds, the electronics will go into "sleep" mode.

  • The Reset button (smaller hole, right) causes the device to restart. This may interrupt existing Bluetooth connections, ongoing local recordings, etc.

Info

Please be aware that you cannot fully turn off the microcontroller, only set it "sleeping" with the Function button. Accordingly, the battery charge may become low after 7-10 days in "sleep" mode.

(B) Micro-USB socket and status LEDs:

  • white LED:
    • solid glow: electronics are charging
    • solid glow stops: electronics fully charged
    • fast flashing: electronics may not be switched on (and therefore not charging). If the electronics are switched on, the battery may be defective.
  • micro-USB socket: you can use this to charge the battery. To do so, use a commercially available micro-USB cable and plug in the sendance-grid while it is turned on.
  • red LED:
    • continuous red glow: bootloader problem at startup. Try pressing the Reset button, otherwise refer to the FAQ.
    • short flashing when switching on: successful startup
  • blue LED:
    • slow flashing: electronics running but no active Bluetooth connection to the sendance-cloud.
    • continuous glow: electronics running with active Bluetooth connection to the sendance-cloud.
  • no LEDs are turned on:
    • This means the device is either "asleep" or the battery level is too low. As such, try turning it on again with the Function or Reset buttons, and/or charge it.
