BACnet Support

Looks good. Did you consider running HA on Docker Containers where you might have a better chance of configuring Docker connectivity to host mode?

Hi GravySeal,

I tried to install the dev version of Bepacom but it fails to install, even after a restart of HA. I can reinstall the release version without issue. Here is the dev install fail message:

Failed to install add-on
The command '/bin/bash -o pipefail -c apk add --no-cache nginx python3 py3-pip py3-setuptools py3-wheel && pip3 install --no-cache-dir --upgrade pip 'bacpypes3<=0.0.79' 'fastapi<=0.103.1' 'jinja2<=3.1.2' 'uvicorn<=0.23.2' 'websockets<=11.0.3' 'python-multipart<=0.0.6'' returned a non-zero code: 1

… BTW, my adapter name is Wi-Fi

Hey Gravy,
I am having some trouble isntalling this. I have BACnet devices and wanted to see if they would talk through this programming. I installed the .zip file and unzipped it through SSH but I cannot seem to find the addon. Kind of a newbie with all this programming stuff. Let me know if you have any ideas. Thanks!

GravySeal · November 21, 2023, 9:32pm

Hey @btingles,

Are you using Home Assistant OS or supervised?
For the installation, you should go to Settings>Add-Ons>Add-On Store.
In the top right select the settings icon and open the Repositories setting. There you can paste the link to the repository:

When you refresh the page, the repository should appear as “Bepacom Add-on Repository” below Official Add-Ons. There you can select to install the regular version like any other add-on.

If everything works correctly with the add-on, you can install the complementary integration. This is only after you’ve verified you can see all the BACnet devices you need in the web UI of the add-on. Feel free to DM me for more help!

Installed the add-on.
I see the BAKnet data I need.
I don’t understand what to do next so that this data appears in Home Assistant. Tell?

jaymemaurice · November 30, 2023, 4:57am

I think I reproduced this with home assistant supervised in both dev and normal version.

is ifconfig the right thing to use here?

@jaymemaurice @cerveza_stalone
I can’t, for the love of me, use that Node in Node Red.
I can connect to my Trend device with Yabe and I get these:

So, about the Trend device have these data:

IP: 192.168.45.65
port: 47808
device ID: 1001
various Objects ID

The node I’m using is node-red-contrib-bacnet, In the node “Simple Read” what should I put in there fields?

What’s an instance?
Should I put the Trend IP in the Device os in the Client? I have just 1 BacNet device, what should I put in the other?
Thanks in advance!

jaymemaurice · December 8, 2023, 4:53am

It’s confusing eh?
Create an instance for each instantiation of an ID you want to read - in my use I have a thermostat connected to a Delta BAS… I want to read the thermostat/co2/binary state of motion sensor etc…
each of these things are an “instance” of something to read I guess.
The name doesnt seem to matter. Eg. LinkNet1BathroomTemp isnt anywhere in my Delta configuration. What is important is my thermostat variable for Temperature is 101.
Type is the type of bacnet variable - eg 0 is ~~integer~~analog-input, 5 binary-input etc. this lives in some standards doc - why this isnt configured as part of the “instance” I couldn’t tell you. Why the type isn’t an enumerated drop down… not sure… Perhaps I don’t understand this well enough??
Device is the device ID you are querying I think… in my case my BAS is 100 and all the thermostats connect over it so it has all the variables available in its GCL.
Client is the node red server’s bacnet instance you are creating here and all your simple reads will probably share the same client.

jaymemaurice · December 8, 2023, 5:17am

sorry type 0 is “analog input” so here in my BAS I have Master_SPT which is 100.AI101 which is instance 101 object type 0… there is no other 100.101(type 0) but there may be other 100.101’s of other type like Binary Variable or Binary Input etc.

So /you/ from your example should be able to query device id 1001 for type 0 instance ID 1 7 8 35 36 etc.

In my screenshot I can get my humidity from device 100 instance 102 type 0. In my delta the first linknet connected thermostat connected to the bas is 100, second at 200 etc. and AI 1-7 are physical GPIO on the board itself. I have an application controller that connects via rs485 and gets it’s own ID and has it’s on analog inputs and outputs… an can also have more linknet devices connected to it…

And it seems the plugin defaults to type of 8 which from my research is type “Device”

Not very helpful but you might be able to read type 8 instance at 1001 from device 1001… probably everyone using this plugin will be querying types 0 though 5.

jaymemaurice · December 8, 2023, 5:22am

This document seems to cover the types:

playernine · December 8, 2023, 9:25am

Not sure if you are still interested in this topic… I have a same setup from one of my client who uses daikin VRV. We added a bacnet gateway from daikin. To integrate with homeassistant(since there is no bacnet support back then), we written a script in Python using FastAPI as a gateway from bacnet to RestApi.

andrex · December 9, 2023, 10:13am

I’m getting somewhere: I kept getting “ERR_TIMEOUT” because I had YABE always open.
Now (with YABE) closed, I get Error: BacnetAbort - Reason:5.
I see that you’re talking about Instance ID (which in my case is 1001), but I can’t find where to put it.
This is my setup:

Thanks again!

andrex · December 9, 2023, 10:14am

I’d like to take a look at your script!

playernine · December 10, 2023, 3:47am

I am unfortunately unable to share the complete project as it is stored in the company codebase. But if you are able to provide a couple of screenshot with the objects using BDT(bacnet discovery tool), I should be able to mock a script which acts as a gateway for bacnet and restapi

jaymemaurice · December 12, 2023, 2:10am

Where you have type ANALOG_INPUT put the integer 0
Edit device “Trend” and put 1001 for it’s name and put the IP of the BACnet interface on the device.

jaymemaurice · December 12, 2023, 2:15am

It looks like bepacom add-in has been fixed for me in the dev version.
If you have bridge interfaces on your supervised home assistant to run KVM VMs, you will need the latest version or you will get the problem I encountered starting ngnix

I am going to be using this add-on instead of Node Red because it automagically adds each bacnet entity and subscribes to CoV rather than polling. Looks like this might be the best thing next to native bacnet in home assistant and I am very greaful to the developers for the work they have done for the community.

andrex · December 12, 2023, 7:10am

Solved, THANKS!!!
I didn’t have to use the device ID 1001. I’ve solved it over the weekend and…I really don’t remember what I’ve changed that made it works :man_facepalming
Thanks for your tips!

ryano1 · December 15, 2023, 4:33am

Currently having issues with detecting devices (alerton vlca-1688) with Bepacom Development version, its detected the device in the logs, however has returned errors, Anything to try?

log below:

KeyError: ‘device:2000’
ERROR: An error occurred: ‘IAmRequest’ object has no attribute ‘apduInvokeID’
