Door Monitoring


Supported in: SimplePack 3.0/4.0 Plus Door or Full, SimpleIndustry Door or Full

Intended for: End users and integrators & platform providers to understand device behavior before direct implementation and fine-tuning (for those who want to integrate the device into their own platform, the API 6 firmware documentation is here.

Use case description: For monitoring doors, we will use the SimplePack mode Door mode. The device behaves like this: You will receive a message whenever the door is moved. The device uses the magnetometer to determine change of orientation and picks up smooth movement (which the accelerometer struggles with sometimes). Simple, long-lasting and reliable. If you want to know the state of the door (open/closed), we suggest you use the reed switch in a reed switch mode.


Before-you-start checklist (you should have everything on the list if you went through the first message guide):

✅ Hardware/devices ✅ Sigfox connectivity ✅ Sigfox coverage where you need it ✅ IO Frog platform account and access ✅ Correctly set-up callbacks in the Sigfox backend (if you're using your own connectivity) ✅ You're receiving messages from your devicesEverything is fine!

Step-by-step setup guide

1. Go to the IO Frog platform and login with your account.

2. After you login, head over to your profile in the top right and make sure your Experience level is Expert, otherwise you will not be able to change device downlink - if necessary, increase your level and hit Update to save the changes.

3. Go to the All devices tab and click on device Setup.

4. In the downlink tab, set the mode to Magnetometer mode (0109 in the top bar), hit Update.

5. Press the button of your device for 10+ (SP 2.0) or 6+ (SP 3.0 Plus) seconds, this will trigger downlink with the new settings - the LED will keep blinking for about a minute.

If you're working with the SimpleIndustry or the SimpleMeter, you need to either wait for the heartbeat that will request downlink (older prototypes) or you will use a magnet on the reed switch instead of pressing the button. The time of operation is the same (6s+ of magnet presence to trigger downlink, 2-4s to disarm device, 1s to arm).

6. Once the LED stops blinking, you can place the device where you need it: use a heavy-duty double-sided tape to stick it to the door. Please note that if the door happens to be made of metal, it's preferable to use a 2-3 cm plastic spacer (read more in our article about device placement).

7. Once placed, activate the device by pressing the button and try opening and closing the door to see if you receive the message right. There, all done!

Please note that Sigfox has a 90% delivery success rate. It's possible that the downlink will not be received by the device, the best way forward in this case is simply repeating the whole process from Step 4 onwards.


  • If you're getting false or limited reports of usage, try playing around with accelerometer sensitivity settings (the higher the number, the less sensitive the sensor).

  • If you're losing a lot of messages, set up 3x alert repetition. This will better the performance of your device and you should lose less messages.

  • Public data sharing: IO Frog also supports public channels, where you can add multiple devices and display data from all of them at the same time, including their position on a world map. It's very cool and we highly suggest you take a look! Here's our coffee project and here's how to set a public channel up.
