determine writeable values

[zivillian]

We need to know which values can be set by the app and which busAddress has to be used

[zivillian]

ReadOnlyConditionId in ParameterTemplates.xml looks promising

[zivillian]

There are only 7 ReadOnlyConditionId (out of 4661) with a real condition (not just True or False) so it would be an option to just skip those.

[zivillian]

but according to the dumps, the busAddress is different:

• 0x35 for reading (as announced in read-systemconfig-response)
• 0x30 for writing (as seen in ism7proxy)

[copystring]

Same goes for 0x8 => 0x3
I guess it's always offset by -5

[zivillian]

Each master also has a dedicated slave address which can be found by simply adding 5 to the master address (wrapping at 256, i.e. 255+5 is 4).

There are additional devices on the bus, which are not reported in the read-systemconfig-response. There presence is hardcoded in the smartset application and evaluated during the initial connect. One example is the WWSystem device (DTID 35000) which is automatically added to the smartset DB if there is a BM-2 with the corresponding configuration. Those devices have additional properties which can be set like Warmwassersolltemperatur eingestellt.

In my setup there are actually two of those properties with PTID 35009 and 35014 which both have the same TelegramNr 19. 35014 seems to be hidden by the ControlType Client_NO_DISPLAY, but according to the DB it was used for wrtiting.

[zivillian]

I think we need to extract more information from the smartset DB.

  • Id
  • IsVisible
  • ReadBusAddress
  • DeviceTemplateId (DTID in DeviceTemplates.xml)
• ExchangeParameterBundleBOs
  • DeviceId
  • ParameterId (PTID in ParameterTemplates.xml)
