When Easee Equalizer appears as offline in the app, it usually means that it is not connected to a WiFi network.
It is important to note that the Equalizer can still operate without WiFi. Even if the device appears offline in the app, it will still be able to communicate with the charger via internal radio communication, as long as it is within range.
This means that functions such as load balancing can still work, but you will not be able to see live data from the Equalizer in the Easee app.
Common reasons why the Equalizer is offline
The most common reasons why the Equalizer has lost its WiFi connection are:
The WiFi network has been changed or updated
The password for the WiFi network has been changed
The Equalizer is out of range of the WiFi signal
The network is not compatible with the Equalizer
How to reconnect the Equalizer to WiFi
You can connect the Equalizer to a new WiFi network via the Easee app.
Follow the steps below:
Open the Easee app
Navigate to the Equalizer product page
Go to Equalizer settings
Select WiFi
Follow the on-screen instructions to add a new network
The WiFi information is transferred from your mobile phone to the Equalizer, so make sure the phone is available together with the Equalizer.
If the connection still does not work
If the Equalizer still does not connect to WiFi after following the steps above, it is often due to compatibility between the WiFi network and the Equalizer.
It is also important to note that the charger can sometimes connect to WiFi even if the Equalizer does not. This is usually due to adjustments and updates that have been made to the charger over time.
In the rest of the article, we will take a closer look at specifications recommended to check before attempting to reconnect the Equalizer to WiFi again.
WiFi specifications
- WiFi must be password protected.
- Easee products use 2.4 GHz IEEE 802.11 b/g/n.
Easee products do not support 5 GHz WiFi or WiFi 6 (802.11ax). - The WiFi signal must be at least -75 dBm to ensure a stable connection.
- It is not possible to assign a static IP address to a charger or Equalizer. A DHCP server must assign the IP address.
- If you are using a mesh network and cannot connect, turn off the network and connect directly to the router, then turn the mesh network back on.
Password requirements
An SSID password can be up to 31 characters long. The characters period (.), slash (/), backslash (\) and hyphen (-) are not allowed in the password.
Additional technical WiFi requirements
Check these requirements for outgoing traffic if you still have problems connecting to WiFi.
The following ports must be open for outgoing traffic and allow related sessions:
- TCP 80 - HTTP (open by default)
- TCP 443 - HTTPS (open by default)
- TCP 1883 - MQTT
- TCP 8883 - MQTT
- UDP 53 - DNS
- UDP 56906 - client-to-client communication
- NTP 123 - TCP & UDP
These settings are usually not necessary on a home network. It is not uncommon for corporate networks to block some outgoing traffic.
The following web addresses must not be blocked by the firewall:
- https://api.easee.com/
- https://amazonaws.com
- https://google.com
