It is many different issues that might cause Pulse not to work as intended. Much of this you can solve yourself by checking the Pulse LED light and testing a few troubleshooting steps.

First thing to check when you are troubleshooting Pulse is if it has any light in it's LED and what color it is.


Pulse have no light:

If Pulse has no light, it's usually caused by one of three things:

Pulse is frozen: Try to disconnect Pulse from the meter for 2 minutes and then reconnect again. If this was the problem Pulse should light up quite quickly (white pulses), but might use 5-40 minutes to start up sending data again (depending on the type of meter and version of Pulse).

Fault on the HAN-cable: The fault might be caused by a defective RJ45 cable. To test this, please try to connect Pulse to your meter using another RJ45 cable (CAT 5e or newer).

Do you have an Aidon meter? If the HAN-port is not activated on an Aidon meter, it will not supply Pulse with any power. Contact your grid company and ask them to send an activation signal to the HAN-port.

If non of this works when Pulse has no light, please contact us through the chat. Mention what steps you have tried to do, and also connect Pulse to a USB power supply.


Yes! Pulse has a light:

How the Pulse light shows indicates the status it has right now. Below you will find the different kind of lights that Pulse will show you if something isn't right. It might be that the intervals of the pulsation isn't totally correct, but it should be close.

Pulse is not set up correctly: (White-red-nothing pulsation)

Pulse is connected to your energy meter, but is not set up correctly in the app. Connect Pulse to a USB power-supply, and it will change it's light to green. Go into the app to Power-ups, and on the page that comes up choose Pulse. Click on Connect and follow the on-screen instructions.

No HAN-data: (Red-green pulsation)

Pulse is set up correctly, but we are not receiving any data from the energy meter. Contact your grid company to activate the HAN-port. If it already is activated, try to connect Pulse to the meter with another RJ45 cable.

Pulse can't connect to WiFi: (Red continuous 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.

Pulse can't connect to our servers: (Red pulsation)

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

If it doesn't help to restart the router/modem, please try the following:

  • If you have a strong firewall you will need to set up a rule for Pulse. Pulse needs access to a1zhmn1192zl1a.iot.eu-west-1.amazonaws.com at port 8883.

  • It might be a problem with the DNS from your internet provider. Please try to ping a1zhmn1192zl1a.iot.eu-west-1.amazonaws.com and see if you get a response. If you do not receive a response please contact you internet provider to solve this.
