Smappee EV chargers

The EMS connects to the Smappee Flex (Genius II) on the local network. This gateway exposes the connected EV chargers through its local MQTT broker. The controller reads charging states and energy measurements and sends charging commands through that connection.

Connection settings

Enable Local MQTT in Smappee

1. Make sure the Flex (Genius II) is activated at the location in Smappee.
2. Open the Smappee mobile app and go to Control → Smappee Store.
3. Choose Manage, find the MQTT app and select Install Integration.
4. Generate and retain the local MQTT username and password.

These are credentials for the local Smappee gateway, generated in Smappee. They are not credentials for the Eniris MQTT broker. A separate connection to the Eniris broker uses credentials requested through the distributor.

Add the chargers

1. Connect the controller and the Smappee gateway to the same local network. Allow the controller to reach the gateway on TCP port 443.
2. In the device wizard, choose EV charging station → Smappee.
3. Enter the gateway's local IP address and local MQTT credentials. Keep port 443.
4. Leave Charger UUID blank to discover chargers exposed by that gateway, or enter a specific UUID from Local MQTT in the Smappee Expert Portal.
5. Run discovery, add the required chargers and check their charging state and measurements.

If a UUID copied from the mobile app does not find the expected charger, leave the field empty and run discovery again. The charger must be communicating with the gateway's MQTT broker to be discovered.

Multiple connectors and charging states

A single gateway can expose multiple connectors. Each connector appears as a separate child device and can be controlled independently while sharing the gateway connection.

If the connection fails

• Verify the gateway's local IP address and TCP port 443.
• Check that Local MQTT is enabled and that you used its generated credentials.
• Check whether local MQTT access was revoked in Smappee.
• For an empty discovery result, check the gateway connection and try without a charger UUID.
