[BUG] Bacnet - some Tags don't show up

[TheGreyDiamond]

Describe the bug
Some tags do not show up when using bacnet. I've integrated a Siemens POL908 Climatix controller (for an HVAC system). However, not all fields show up. Notably the OpModeAutoManStTmpSwtch option (Used to set operating mode) wont appear. Using the Python BAC0 library I can discover and control this endpoint. It shows up as a "Multiselect" (or similar - at the time of writing the system has gone offline for an unknown reason and I can only remote in) type, which I assume to be part of the problem.

Environment

• FUXA version: Version 1.1.19-1500 (from bacnet-Branch)
• Node.js version: 18.20.3
• npm version: 10.7.0
• Platform/OS: Rapsberry Pi 3 / Debian

Hi, Thanks for the report.
@lpaszcza do you have any idea what could be the problem?

[lpaszcza]

@TheGreyDiamond I suspect that you are trying to read an MV type object that is not supported in the current version.
@unocelli I've added a new PR to the bacnet branch, which includes a fix that adds support for MultiVariable points and others.

[TheGreyDiamond]

Sounds, good. Currently downloading and installing your PR, will hopefully be able to try it later today..

Trying your branch I'm now unable to find any endpoints.. I can discover the node and this screen shows up:

Trying to open the last dropdown I get the following error in the log:

[ERR]  device-browse: undefined

This is my device config:

@TheGreyDiamond, thanks for your feedback. I need to investigate this case further. Could you tell me how many BACnet objects you are trying to read from the Siemens device?

[TheGreyDiamond]

Sorry for the late reponse. BAC0 reports 94 points.

[lpaszcza]

@TheGreyDiamond are there any AV or BV type objects on the Siemens device? Does the master-Branch version of FUXA display these objects?

[ERR] device-browse: undefined
The error you are encountering indicates that the full list of objects could not be read. Have you tried resetting the BACnet interface in FUXA?

[TheGreyDiamond]

Hey there. Fairly certain that there are AV and BV-type objects. The BACnet branch seems them. The master branch of FUXA did not work for me (at all, I couldn't get Bacnet to turn green).

I've tried multiple setups and reseted it a few times.
