Actual Humidity

[pepsonEL]

Hi. I have controller VRC700 in my Vaillant. It show me in configuration menu > installer show me Actual Humidity in Room.

How i can read this value by EBUS in Home Assistant ? I dont see this value in entity from auto discovery.

Found it (for VRC720): (edit: these registers do not seem to work for the VRC700, someone whould try to find them e.g. by logging ebus traffic between internet gateway and VRC700).

Following definitions were added to the CSV of CTLV2 (defaults were not added but indicate the sections of the ctlv2.csv were the definition wass added):

*r,,,,,,B524,02000300,,,IGN:4,,,
r,,z1RoomHumidity,,,,,2800,,,EXP,,%,room humidity zone1

*r,,,,,,B524,02000301,,,IGN:4,,,
r,,z2RoomHumidity,,,,,2800,,,EXP,,%,room humidity zone2

*r,,,,,,B524,02000302,,,IGN:4,,,
r,,z3RoomHumidity,,,,,2800,,,EXP,,%,room humidity zone3

This seemingly doesn't work on the 700:

2023-10-15 15:52:19.964 [update error] unable to parse read 700 z1RoomHumidity from ff15b52406020003002800 / 00: ERR: invalid position
2023-10-15 15:52:19.964 [mqtt error] decode 700 z1RoomHumidity: ERR: invalid position

.. after adding

,,z1RoomHumidity,,,,,2800,,,EXP,,%,room humidity zone1

to 15.700.csv

@Wireheadbe, @pepsonEL, Have you moved forward with reading humidity for VRC700 using ebusd?

If someone of you has internet gateway and native MyVaillant app there are chances to get the format of the reading command on the bus, as some users of VRC700 report that they observed humidity readings in the MyVaillant app for the VRC700.

BTW: I've also tried the above command from 720 found by @chrizzzp, but without success.
