simpleSUMs arrive from the factory fully assembled, but in a sleep state. You will not see them in the Geocene app until you wake them up.

  1. Make sure you have an Android device with the Geocene mobile app installed. For detailed instructions, see:

    Install the Mobile App

  2. If your phone has an NFC reader:

    1. Bring the back of your phone right next to the simpleSUM you want to install (2-10 cm away)

    2. Wait for the phone to buzz and say “Connecting…”

    3. Move the phone away

  3. If your phone does not have an NFC reader

    1. Squeeze the middle of the logo on the simpleSUM to press and release the hidden button

    2. The simpleSUM should appear on the list in the mobile app with a green dot next to its name. The name will look like “SSUM-ABC123”. This is “SSUM-” (short for simpleSUM) followed by 6 random characters (0-9 and/or A-F). It is also printed on the label. The name you see on the screen should match the name on the label.

    3. Tap the simpleSUM name on the screen.

    4. Your phone should now say “Connecting…” Wait for your phone to connect to the simpleSUM. This should take about 5-10 seconds but may sometimes take longer.

  4. Once you are connected, you may be prompted to upgrade the simpleSUM’s firmware. If you do not see this prompt, proceed to step 4. If you do see this prompt:

    1. tap “Yes (Recommended)” and wait approximately 1 minute for the upgrade to complete.
    2. Hit the “back” button on your phone and return to step 1.

If you need to move a simpleSUM to a different stove, started it by mistake, or need to take it out of commission for any other reason, you should hit the red Stop button. After confirming, this will return it to its sleep state. You can wake it up by repeating the process outlined above.
