[HELP] How to add ocpp charger using thingsboard gateway

[Vaghulkumar95]

Describe the issue I'm trying to connect an EV Charger using ocpp and I'm unable to connect, please help. I mainly need to know how to configure the host and port in the charger. And how to set the endpoint?

Hi @Vaghulkumar95.
Thank you for your interest in ThingsBoard IoT Gateway.
Your issue was registered, please wait for response from engineer.

Hi @Vaghulkumar95,

Please try to use something like 0.0.0.0 as a host and port more that 502 (e.g. 5020), for your connector, because in linux you should have root access to bind ports in range 1-1024.

Hi @imbeacon,

Can you please confirm if I have set the properties correctly, still I'm not getting anything

Hi @imbeacon,

Just wanted to follow up on this? We are trying to get this EV Charger connected and client is waiting for the connection results. Any inputs on this is highly appreciated.

Hi @imbeacon,

I'm now able to communicate with the battery. I had to give the domain as the hub's IP address and port as 5020, and in json I did give 0.0.0.0 and port as 5020 and it was able to connect. Can you let me know how to get the status notification, and hearbeat in the json? What would be the message filter type for these?
