Water Heater: Set operation mode performance

I’m trying to change the operation mode on my hot water using the bosch integration. I’m using the v0.18.3 version from HACS

my entity is: water_heater.dhw1

If i call a service via Home Assistant dev tools like below:

service: water_heater.set_operation_mode
data:
  operation_mode: high_demand
target:
  entity_id: water_heater.dhw1

I have no issues getting it to change between High Demand (On) and off. However, If I try and do exactly the same with a performance which is one of the modes on the operations list - and one I can set in the Bosche app it doesn’t do anything. the spelling is lowercase performance as if I use uppercase Performance it gives an error so I know the actual enumeration is correct.

Just to show it switching between the other operation modes with no issues:

Is there something I may be missing?

I’ve tested and can now set the HW to Performance, looks good thanks @pszafer

The same issue that I’ve raised in #159
