How to reset a sensor

There are a few cases that may require a sensor reset. Here's how to do it.

When you might want to do a soft reset

Once a Conserv sensor is connected to the network and sending data, it should continue to run without interruption or manual intervention. However, there are a few cases where a reset may be required:

  • You have checked the issue is not actually with the gateway as opposed to the sensor (other sensors on the same gateway have no issues or the gateway signal is down/low). If you think the issue might actually be related to the gateway, please check our support articles to troubleshoot your gateway.
  • Bring the sensor right next to a gateway and see if it starts working. It could have been a range issue. If it does not come online within 20 minutes, and you still need to do a reset, it is best to perform the reset procedure within range of the gateway as it may deplete the sensor's batteries if it attempts to rejoin the network for a prolonged period of time. 

Note: After completing a soft reset, give the sensor 15-30mins to come online before you move to the next step. It might just need a few minutes.

If you haven't already, please read this article on troubleshooting a sensor that has stopped reporting.

How to soft reset your Conserv sensor

To reset a sensor, turn the device over and look for the circle on the back labeled "RESET" (See photo below).

Items that you may use to press the button

  • The back of an earring (that is not too thin as it can slip off to the side instead of depressing the button)
  • A paper clip
  • The same pin that comes with your phone to take out SIM cards.
  • A small Allen key
  • A small nail

Push through the label to make a hole and depress the reset button.  You'll feel it 'click' when it is depressed (you should not have to press very hard). 

After pressing the reset button, you should see a light flash on the back of the sensor. The color will depend on the version of your sensor.

  • For older sensors: A brief blue light flash is confirmation that the sensor is attempting rejoin the network. This should happen in about 10-15 seconds after pressing the button.
  • For SCS-3 sensors: You will know the reset has been successful if you hear a beep and an orange light flashes from the back of the sensor.

If the reset was successful, data should begin flowing again in your account within 15 minutes.

If you do not see lights flash or if the sensor does not start reporting even if it's within range of the gateway, please try a hard reset. If the sensor doesn't connect for the SCS-3, pay attention to the color of the lights so you can tell us which ones you saw when you open your support ticket.

Useful tips on pressing the reset button

The actual hole under the sticker label may not be exactly in the middle of the drawn circle. Poke around a bit in that circled area to find the hole. You will need to punch through the label.

Figs 2-3. The hole isn't always in the middle of the circle draw on the label. Make sure you poke around a bit if you need to. In this sensor below, you can see the hole was off to the left while in the one below that, the hole was a little bit towards the top left.
