HwcTimer fields are read-only (r5) for Vaillant 450 - request rw flag

[julienb20000]

Hi,

I have a Vaillant boiler with a 450 thermostat connected via eBUSd.

When I run:
ebusctl find -f -c 450 HwcTimer_Monday

I get:
r5,450,HwcTimer_Monday,...

The message is defined as read-only (r5) but I would like to be able to write
the hot water timer schedules from Home Assistant via MQTT.

Could the HwcTimer_* fields (Monday through Sunday) for the 450 device
be changed to rw to allow writing?

Thank you!
