Protocol DeltaSol MX

[ramack]

Hello,

I have a DeltaSol MX and would like to talk to it using a linux box. I
found the vbus spec with the definition of some device specific
information, but the MX is not yet listed there. Does anyone know more
details about the MX or any plans of Resol to release a new document?
(maybe you Daniel Wippermann?)

Kind regards,
Raphael Mack

Dear Mr Mack,

yes, there will be an update to the VBus protocol specification in the near future, the document is currently reviewed, but not just yet ready for the public :)

Down below you find an excerpt of the DeltaSol MX protocol specification (based on MX firmware 1.00). There were some additions for the firmware 1.01 (heat quantity and heating circuit information), but I currently can't find them... Some translations for the "Name" column:

Temperatur Sensor x => Temperature sensor x (hmmm, that one was obvious :) )

Einstrahlung Sensor x => Irradiation sensor x

Volumenstrom Sensor x => Flow sensor x

Druck Sensor x => Pressure sensor x

Drehzahl Relais x => Pump speed relay x

Systemdatum => System date

Fehlermaske => Error mask

Best regards,

Daniel

Dear Daniel,

I have a DeltaSol BX-Plus and would like to use the Vbus for a communication with my Home Automation.
I found the vbus protocol specification, but the BX Plus is not yet listed there.

Do You also have these specs for me?

Best regards
Andreas
