Setting up TeltoCharge

[gitantti]

Hello,

I've been trying to get TeltoCharge monitoring and control up and running

Here I have read that someone get this charger working with older FW versions

I have set the ocpp integration in HA, configured the address to my charger and the App says connected. But..
At some point I even got e.g. Energy Active Import Register updated but not any more.
Energy Active Import Register is forzen to value 116.20kWh.

Some communication there is working as status connector, vendor, FW version, serial are updatd.

I checked the log and some rejection there is.

2025-12-11 21:36:50.388 INFO (MainThread) [ocpp] 6000005791: send [2,"7aafc04e-183c-49be-acd8-ab9ff1e61047","TriggerMessage",{"requestedMessage":"StatusNotification","connectorId":1}]
2025-12-11 21:36:50.685 INFO (MainThread) [ocpp] 6000005791: receive message [3,"7aafc04e-183c-49be-acd8-ab9ff1e61047",{"status":"Rejected"}]
2025-12-11 21:36:50.687 WARNING (MainThread) [custom_components.ocpp] Failed with response: Rejected

Any ideas what's wrong here?

According to this info: https://wiki.teltonika-energy.com/index.php?title=OCPP_1.6_JSON_guide_EVC2#OCPP_IMPLEMENTATION
Only Energy Active Import Register is provided by default.

Here (https://community.teltonika.lt/t/teltocharge-ocpp-missing-meters-and-stats/16195/3) is advised that with this command additional measurands should be available.

ocpp.configure
data:
  ocpp_key: “MeterValuesSampledData”
  value: “Energy.Active.Import.Register,Current.Import,Current.Offered,Temperature,Voltage,Power.Active.Import”

Tried to run this in the HA developer tool actions but according to logs this command is also rejected.
