Do sensors need state_class: measurement

[TonyM1958]

A number of the BMS sensors (11037, 11041, 11042, 11045, 11046) don't have

state_class: measurement

in their definition in modbusUSB.yaml so, as I undestand it, won't be storing any long term statistics whilst most other sensors do have this.

Is this intentional or should these sensors also have this property?

[TonyM1958]

only works for device_class power. For sensors with device_class energy, a state_class of none, total or total_increasing is required e.g. for Solar Energy Total.
