FCSP Charging Stats

[ericpullen]

I just got the FCSP installed and didn’t see anywhere in either app the ability to see the amps that it is drawing when plugged in. Is this somewhere I’m missing?

Poking around the unit, I got it to respond to a few commands:
https://192.168.1.241/f2134234124124
This gives me a rundown of some of the API's that it might respond to.

https://192.168.1.241/api/v1/chargerinfo gives this Django error:

But also tells me other pathnames of the embedded system, which looks to be this reference design:https://www.ti.com/tool/TIDC-EVSE-WIFI

I'll keep digging in to see what else I can get it to respond to.

I haven't been able to find anything.

The FCSP runs on an adaptation of Siemens' Versicharge SG.

The only way we've been able to see the charging current is by using OBD information from the truck.

After the …68… software update, I remember reading others no longer could access their charging history when using the FCSP…..me too. Is that the case for others?

Mine uploads its data and I can see it for past days.

I've been going in circles of research trying to find a way to get the real-time charging data from this unit into Home Assistant, and finally stumbled upon this same error. I've also gone down the OCPP route in hopes there'd be a solution, but keep running into dead-ends.

It looks like port 22 on the device is open, so I'm wondering if there may be some standard credentials for this unit that will enable this access or something via SSH. My Station ID and access code do not work for this.

@ericpullen Have you found anything else since your last post on this?

No, I got sidetracked on other projects and haven’t really looked at it much more. My last point was starting to sniff the traffic between the FCSP and the internet to see if I could at least see the api endpoints it is sending data out to, but it was all encrypted and couldn’t gather much without some kind of MITM to decode the traffic.

Does your charge history only log once the cable is unplugged from the vehicle? We have TOU pricing here in Ontario, so if the vehicle starts charging at 7PM, and is finished by 8PM, but I don't unplug it until say 9 AM the next day, it doesn't show any charging until the period immediately preceding being unplugged, even though the electricity was actually delivered the night before.

That seems consistent from what I’ve observed. The level of detail in the data in pretty disappointing.
