Ocpp, possible to send heartbeat signal? - Jonas S - 09.09.2022
Hello
Would it be possible, maybe through websocket? to send heartbeat command to ocpp backend?
What I'm really after is to use a energy meter and send consumption to the backends Load managment but if I could mange to figure out just the heartbeat function I should be able to get the rest working by my self
json script for heartbeat response:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "urn:OCPP:1.6:2019:12:HeartbeatResponse",
"title": "HeartbeatResponse",
"type": "object",
"properties": {
"currentTime": {
"type": "string",
"format": "date-time"
}
},
"additionalProperties": false,
"required": [
"currentTime"
]
}

We're looking into OCPP at the moment. Examples will be posted when ready.
RE: Ocpp, possible to send heartbeat signal? - admin - 14.09.2022
See attached code for OCPP v1.6 client example.

Cool. Thanks

Many thanks, looks promising! Do you see a difference to using it with OCPP 2.0?
RE: Ocpp, possible to send heartbeat signal? - admin - 19.09.2022
The base protocol is the same but the command structure is different. Meaning this example won't work with 2.0 without modifications.
RE: Ocpp, possible to send heartbeat signal? - pioneersteffen - 20.09.2022
Thanks admin for the quick reply! Are you planning to supply also a template for OCPP version 2.0 in future?
RE: Ocpp, possible to send heartbeat signal? - admin - 21.09.2022
Attached v2.0 client example.

Many thanks for the prompt help!

Thanks for sharing examples.
I ran this in a Resident with the user.websocket and get
arg1 string: ws connection failed
arg2 string: connection refused
tried it on an Easee chargebox.

This example emulates a charger so LM acts as a client. Connecting charger to LM is a different thing.

Okey, but is it possible to connect a charger to LM via OCPP for doing a smart charging solution?
Heres the developer doc from Easee

Possible but we don't have a ready example at the moment. See this for Easee connectivity: https://forum.logicmachine.net/showthread.php?tid=3301

Okey thank you!

Is there any solutioon to take information from EV CHARGING Expert SCHNEIDER HMIBSC...
For example take the total/zone consumsion of evlink.... I know we can communicate modbus to the evlink (but I have 20 evlink). I was looking for a solution to interface with the SE EV HMI.
Do you know it ?
thanks

The EV Charging Expert does not expose that information in the API they developed for the EVCE.
You are better off requesting the info over modbus tcp.
RE: Ocpp, possible to send heartbeat signal? - domotiqa - 27.09.2024
ok
I ssaw that we can provide ocpp server on the EV but not yet implemented on LM I guess
I didn't know there was an API
when you say modbus ip you mean to the evlink not the EVCE, cause I didn't find any modbus register for it, only for the evlink station

Yes, I mean polling the EVlinks via modbus TCP.
