What should I do if I hear two low beeps (low battery) when powering up my Node-S, and no data appears on Dashboard?

If your Node-S gives two low-pitched beeps when you power it up — and then no data shows up on the Dashboard — it almost certainly just needs charging. This article explains why and what to do.

What's happening​

Two low beeps on power-up means the battery is very low. This commonly happens when:

  • You've just received your Node-S, especially if it sat in its box for a while.
  • You're redeploying a Node-S after a period of inactivity.

When the Node-S powers up and emits two low-pitched beeps, the battery is low. The device won't start uploading data until it has charged above a certain threshold and exits deep sleep mode.

What to do​

  1. Charge your Node-S for at least 24 hours when you first receive it or redeploy it, so it reaches an adequate charge.
  2. Once it's fully charged and configured, monitor its battery percentage from the Clarity Dashboard — see the Device Status Details page.

You're done! Once charged, your Node-S will exit deep sleep and start uploading data.
