Free OCPP 1.6J server for the Fronius Wattpilot charger

Point your Fronius Wattpilot (11 / 22 kW) to our OCPP 1.6J server to control who charges, measure kWh per session, and start or stop charging from your phone. Free with EzGYM.

The Fronius Wattpilot (11 / 22 kW) includes network connectivity with the standard OCPP 1.6J protocol (JSON over WebSockets). Using OCPP, the charger talks to a central server to validate RFID cards, report live kW power and log the kWh of every session. EzGYM is that central server, for free.

If you run a gym, sports club or customer parking lot, you can require RFID authorization so the Fronius Wattpilot stays locked to strangers: when a member taps their card, EzGYM checks if their membership is up to date and starts charging while they work out.

If you operate a distribution company or delivery fleet with electric vans, you can link the Fronius Wattpilot to your vehicles to track exactly how many kWh each driver charged at the depot and the cost of every session.

From the web dashboard or your phone you can also trigger RemoteStart / RemoteStop and unlock the connector with a single tap, without paying monthly per-plug fees.

How to set it up

  1. 1 Create your free EzGYM account and go to EV Chargers.
  2. 2 Add your Fronius Wattpilot with its rated power (11 / 22 kW) and choose whether to require RFID or set a kWh tariff.
  3. 3 Copy the unique OCPP URL given by the app (wss://ocpp.ezgym.net/ev…).
  4. 4 If the charger asks separately for the “Charge Point Identity”, “ChargeBox ID” or “Identity”, enter the ev… identifier there (the end of the URL) and leave just wss://ocpp.ezgym.net/ in the URL.
  5. 5 Open Solar.wattpilot › Internet › OCPP › OCPP Server URL on the Fronius Wattpilot, paste the OCPP URL and reboot the charger: within seconds it shows Available in EzGYM.

Frequently asked questions

How do I connect the Fronius Wattpilot to EzGYM?

Add the charger under EV Chargers in EzGYM and copy the unique OCPP URL shown in the app (wss://ocpp.ezgym.net/ev…). Then paste it into Solar.wattpilot › Internet › OCPP › OCPP Server URL on the charger.

Does the Fronius Wattpilot use wss:// or ws://?

Use the URL that starts with wss:// (port 443, encrypted): it is the one the app gives you. If your Fronius Wattpilot firmware only accepts plain ws://, write to us with the brand and model.

Can I lock the Fronius Wattpilot so only authorized members or drivers can charge?

Yes. Enable “Require RFID card” on the charger settings in EzGYM and the Fronius Wattpilot will verify every card in real time before delivering power.

How much does the OCPP server cost in EzGYM?

Nothing. The OCPP 1.6J server, RFID card validation, remote commands and kWh session history are free in EzGYM (up to 20 chargers per account).
