Add support for secondary chargebox
It's possible to connect a secondary wallbox to a master, but accEnergy only shows the total energy usage for the master.
However, one can get the energy for the slaves through http://[ip-address]:2222/rest/chargebox/slaves/status. The slaves and total energy usage is also listed through http://[ip-address]:2222/rest/chargebox/config in an array called slaveList .
Here's an example:
$ curl --silent http://192.168.0.100:2222/rest/chargebox/slaves/status | jq
[
{
"reference": "My primary wallbox",
"serialNumber": 12345,

"online": false,

}
]
It getting the accEnergy from the slaves something that you might want to implement?
FYI, the accEnergy on the first wallbox (i.e. the master) listed in the slaves array , is the same data that is listed as latestReading at http://[ip-address]:2222/rest/chargebox/status
@stenrose Sure I can have a look at adding it. I don't have access to a setup like that, so could you provide a reading when you have something charging as well?
Can post the full JSON tomorrow, but the chargeStatus changed to 64 when charging. When charging was complete it changed to 80.
Were unable to find any details on those IDs though.
Forgot about this issue, but here comes a reading when charging.

It's now charging on "Laddbox vänster" which "chargeStatus": 64, indicates. The other box, "Laddbox höger", is not plugged in to a vehicle right now indicated by "chargeStatus": 0,.
When "Laddbox vänster" had vehicle plugged in waiting for schedule set by vehicle it had "chargeStatus": 48. It changes to 80 when completed.
FYI, it is not possible to change mode on the secondary charger, using /servlet/rest/chargebox/mode/{ALWAYS_{ON,OFF},SCHEMA}. So slave chargers are only available for monitoring status, energy etcetera.
I hope you are still interesting in implementing this, and just let me know if you need any further readings.
Any updates on this? Is there a version or an addition to the integration that makes us able to handle two boxes where the Master holds the RPi and the Slave is connected to the Masters RPi. Would be great to be able to see and handle both boxes
If I can get some more logs I can try to add support for it.
What I need is:
http://<ip>:8080/servlet/rest/chargebox/config
http://<ip>:8080/servlet/rest/chargebox/status
http://<ip>:8080/servlet/rest/chargebox/slaves/false
How does it look in the web UI?
Sure thing, here's the output:

And here is how it look in the web UI:
You can ignore the load balancing meters listed in the UI, they are not part of the secondary charger setup.
That should be enough info, are they both GLBDCM-T222FC? The product reporting is a bit strange.
Also, if you don't mind supplying the load balancing info I can try to add that as well while I'm at it.
It should be in one of the following:
http://<ip>:8080/servlet/rest/chargebox/lbconfig/false
http://<ip>:8080/servlet/rest/chargebox/meterinfo/EXTERNAL
2024.9.1 has Slave support, the slaves show up as devices in HA. Doesn't seem to that much you can control on a slave.
Looks like the endpoints for your load balancing are:
http://<ip>:8080/servlet/rest/chargebox/meterinfo/CENTRAL100
http://<ip>:8080/servlet/rest/chargebox/meterinfo/CENTRAL101
