OCPP Proxy (Open Charge Point Protocol Proxy) lets you route your charging stations' OCPP traffic through Monta to any backend system. Use it to migrate chargers to a new backend, run multiple backends at the same time, or test a new system without affecting your live network.
How do I access OCPP Proxy?
In Monta Hub, select Operations > OCPP Proxy.
If OCPP Proxy does not appear in your navigation, contact your Monta account manager to enable it for your operator account.
How do I create a proxy domain?
A proxy domain is the connection point your charging stations attach to. Chargers connecting to the domain's Connection URL are then forwarded to the backend you specify.
- Select Operations > OCPP Proxy.
- Click Create new domain.
- Enter a Name — a readable label for this domain.
- Enter an Identifier — use lowercase letters, numbers, and hyphens only (no spaces or special characters).
- Enter the OCPP URL of the backend you want to route traffic to. The URL must start with
ws://orwss://. - Click Create.
After the domain is created, a Connection URL appears under Connect your chargers. Point your charging stations to this URL.
How do I add destination groups?
Destination groups let you split traffic within a proxy domain across multiple backends. Each group has its own target OCPP URL. New charging stations land in the Default group first — reassign them at any time.
- Open a proxy domain from the Proxy Domains list.
- Click Add destination group.
- Enter a Name and the backend's OCPP URL.
- Click Create.
How do I move charging stations between destination groups?
- On the proxy domain page, select the charging stations you want to transfer. You can:
- Select individual rows
- Select all charging stations
- Paste a list of charging station IDs — one per line or comma-separated
- Click Transfer.
- Select the target destination group.
- To reconnect the charging stations immediately, turn on Restart charging stations after transfer.
- Click Transfer to confirm.
Note: Restarting a charging station while a session is active stops that session.
How do I monitor connections?
The Proxy Domains page shows each proxy domain and its live connection summary. Open a domain to see each charging station's Identity, Status (Online or Offline), last connected time, and current destination group.
How do I export charging station data?
On a proxy domain page, click Export charging stations CSV to download the current list. Use the search filter to narrow by destination group before exporting — the URL updates automatically and can be saved as a bookmark.
