deye_4mptt.yaml PV1,PV3 and PV4 current not usable in statistics

[DHLF]

While the entities for PV1,PV2,PV3,PV4(current) are displayed in the default view(with proper values) only PV2 current can be used in statistic-graph(the other three can't be found).

A quick look into deye_4mptt.yaml showed that PV1,PV3 and PV4 CURRENT are missing the state_class: "measurement" Adding this line properly and restarting HA did not help(well it did but it took some time :) ). The before missing identities can NOW be selected for use in statistic-graph cards.

Hint: Be aware that it will take some time until the values finally show up in the statistical-graph card.

Should be fixed with: https://github.com/StephanJoubert/home_assistant_solarman/pull/304

Still have this issue on PV1 with the deye_string.yaml
