mqtt-hassio.cfg: energy device_class/state_class not applied to kWh sensors (unit pattern ,Wh$ doesn't match kWh)

[ebaschiera]

Summary

In contrib/etc/ebusd/mqtt-hassio.cfg, the type_switch-number rule that assigns device_class: energy + state_class: total_increasing only matches the unit Wh, not kWh (or MWh).

Detail

The rule (around line 197):

    sensor,energy,total_increasing = energy|,Wh$

matches if the message/field name contains energy or the unit matches ,Wh$. The switch key is %name%field,%unit, so a kWh field produces a key ending in ,kWh, and the pattern ,Wh$ (comma immediately followed by Wh) does not match because of the k.

The neighbouring power rule already handles the k-prefix explicitly (,kW$|,W$); the energy (and yield) rules do not.

Effect

Any energy reading in kWh whose name does not contain "energy" gets no device_class and no state_class, so it is excluded from long-term statistics and the Energy dashboard. Real example: Vaillant StatFuelSum (gas counter, unit kWh) is published as a plain sensor.

Fix

See PR — change the unit alternative to also match kWh. The yield rule on the next line (total*,Wh$) has the same limitation.
