Pulse P1/HAN - troubleshooting

Updated this week

There can be many different reasons why your Pulse might not work as it should. The good news? You can often solve the problem yourself by checking the LED light and trying a few simple troubleshooting steps.


Start by checking the LED light on your Pulse.

  • Does it light up?

  • What color is it showing?

These details help you figure out what’s going on, and what to do next.

Excellent! Here’s your text rewritten into clear, customer-friendly language, in Tibber’s tone of voice, with a logical flow and easy reading:


Pulse Has No Light

If your Pulse has no light at all, there are a few possible reasons. Here’s how you can check and fix it:


Pulse is Frozen

  • Unplug Pulse from your electricity meter.

  • Wait 2 minutes.

  • Plug it back in.

If Pulse was frozen, it should light up quite quickly (you’ll see white pulses). However, it might still take 5–40 minutes before it starts sending data again, depending on your type of meter and Pulse version.


Faulty HAN Cable (Pulse HAN only)

  • The problem might be a broken RJ45 cable.

  • Try using a different RJ45 cable (CAT 5e or newer) to connect Pulse to your meter.

(Note: This applies only to Pulse HAN, not Pulse KM.)

Not Connected to USB Power Supply (Pulse HAN only)

During pairing, Pulse needs more power than your energy meter can provide. Always connect Pulse to a USB power supply when pairing.

(Note: This applies only to Pulse HAN, not Pulse KM.)

Using an Aidon Meter?

If you have an Aidon meter, the HAN port might not be activated. Without this, your Pulse won’t receive power.

  • Contact your grid company and ask them to activate the HAN port on your meter.

If you’ve tried all these steps and your Pulse still has no light, please reach out to us in the chat. Let us know:

What steps you’ve already tried
If Pulse is connected to a USB power supply


Yes! Pulse has a light:

The light on your Pulse shows what’s going on with the device right now.

Below, you’ll find the different lights and what they mean if something isn’t working as it should. The timing of the light pulses might vary a little, but it should look roughly as described.

Illustration of the different lights on Pulse.

Static green light:

Pulse has not been connected to our app yet, but it is ready for pairing. In our app, go to Power-ups and choose Pulse. Tap Connect and follow the on-screen instructions.


Blinking green light:

Pulse will blink green when you try to or have connected your phone to the temporary network created by the Pulse. Continue setting up the Pulse in the app.


Blinking strong blue light:

Pulse has received settings from the app and is now trying to connect to the internet and our servers.


Blinking yellow light:

Pulse is automatically updating itself to the latest available firmware when it's being connected in our app. With Aidon and Kaifa/Nuri meters this will automatically happen whenever a new firmware is released. With Kamstrup meters Pulse needs to be connected to an USB power supply to install updates.

Static weak blue light:

Pulse is set up. You should now be able to see your consumption in real time in our app.

Blinking white-red-nothing:

Pulse is connected to your energy meter, but is not set up correctly in the app. Connect Pulse to a USB power-supply, and the light will change to static green. Go into the app > Power-ups, and search for the Tibber Pulse. Click on Connect and follow the on-screen instructions.


Static red light:

Pulse can't connect to your WiFi-network. This might be caused by an error in your router. Try to restart your router by disconnecting the power supply for 30 seconds and then reconnect it again.

Blinking red light:

Pulse is not able to contact our servers. This might be caused by an aggressive firewall or an error on your router and/or modem. Try to restart the router and/or modem by disconnecting the power supply for 30 seconds and then reconnect it.

Some good tips for connecting 👇

If you are having trouble connecting Pulse, try the following:

  • Turn off VPN if you are using it

  • Turn off Cookie blocker

  • Are you using DNS over TLS on your router (encryption)? Try turning this off when you connect Pulse

  • Are you using a work phone? Try using another phone or tablet when connecting

If you turned something off when you were connecting your Pulse, you can easily connect it again when you're done 👍

If you encounter other light combinations than the once we have mentioned, or have any problems with our product, please contact us, preferably in the app or via email to hello@tibber.com. If you are having any problems during pairing, first try again. We are happy to help! 😄
