in the sensors file the unique I'd could collide if two sensors on different hubs have the same name.

consider adding in the hub name to the unique I'd

self._unique_id

When trying to add the custom repository via HACS I get the following message "Repository structure for main not compliant".
Is there an issue with the structure or something with how I'm doin it?

I don't get the same message for other integrations.

Hi,

try this component, but it does not work with the actual HA Version because "setup_Sensors". Can you help?

Thanks, Jochen

Hello,

After some hours of running OPCUA reading, I have this error on the HA log file:

2021-07-24 15:40:57 ERROR (SyncWorker_4) [custom_components.opcua] ns=4;s=|var|WAGO 750-8101 PFC100 2ETH.Application.Publish_NativeMQTT.dwMyCounter, Read Value Error: [Errno 32] Broken pipe

With this config:

• platform: opcua
  scan_interval: 10
  nodes:
  • name: SensorOPC_UA
    hub: WAGO_OPC_UA
    nodeid: "ns=4;s=|var|WAGO 750-8101 PFC100 2ETH.Application.Publish_NativeMQTT.dwMyCounter"
    unit_of_measurement: degrees

I have also a problem to write to a node on my WAGO PLC.
I created automation script like your example and I have the following message in the log

Error: “The server does not support writing the combination of value, status and timestamps provided.”(BadWriteNotSupported) encountered when attempting to write a value of: 5448123 to nodeid: ns=4;s=|var|WAGO 750-8101 PFC100 2ETH.Application.GVL.OPCUA_WritedVar

I have no problem with other OPC_UA client (like UAExpert)

Hello,

can you help me with this please ?
after updating to 2024.1 no more data is coming from the opc server and the error is

ns=2;s=Siemens s7 300.data.1, Read Value Error: argument to node must be a NodeId object or a string defining a nodeid found ns=2;s=Siemens s7 300.data.1 of type <class 'homeassistant.util.yaml.objects.NodeStrClass'>

my configuration
opcua:

• name: opc
  url: "opc.tcp://10.110.10.40:49321"
  session_timeout: 60000

sensor:

• platform: opcua
  scan_interval: 30
  nodes:

  • name: "data"
    hub: opc
    nodeid: "ns=2;s=Siemens s7 300.data.1"

Thank you

Currently, we can only see data for configured sensors. It would be nice if there were a HA entity that represented data from the base hub (connection)

OPCUA server should have some general properties we can pull as well.

need to add ns=0 to pull base namespace server items.

the current basic sensor does not allow for setting the generic SCAN_INTERVAL settings. it appears that we should be able to pull it out from the YAML configuration and input it into the entity setup in a similar fashion to the generic sensor platform .

from datetime import timedelta

SCAN_INTERVAL = timedelta(seconds=30)

async def async_setup(hass, config):
    """Track states and offer events for sensors."""
    component = hass.data[DOMAIN] = EntityComponent(
        _LOGGER, DOMAIN, hass, SCAN_INTERVAL
    )

As discussed in #1 if the initial connect method in the setup method errors out then the component will fail.

we should look at how we can clear setup before connecting to the opc UA targets and make the whole component more flexible.

I'm trying to connect a Siemens S7 with HA.
I can read everything with no issue, but I cannot write.

opcua:
  - name: pastorizzatore
    url: "opc.tcp://192.168.1.166:4840/"
    application_uri: "urn:SIMATIC.S7-1200.OPC-UA.Application:PLC_Pastorizzatore"
    session_timeout: 600000
    secure_timeout: 600000
    security_string: ""

No problem with reading values.

I tried to write

service: opcua.set_value
data:
  nodeid: 'ns=4;i=189'
  value: "mytest"
  hub: pastorizzatore

And have

2023-07-25 13:40:01.215 ERROR (SyncWorker_3) [custom_components.opcua] Error: "The server does not support writing the combination of value, status and timestamps provided."(BadWriteNotSupported)  encountered when attempting to write a value of: mytest to nodeid: ns=4;i=189

Tried with

service: opcua.set_attribute
data:
  nodeid: 'ns=4;i=189'
  value: "mytest"
  hub: pastorizzatore

I receive no error, but I do not see any update on the S7

Any ideas?
Thanks

ps: Using UAExpert I can write with no issue.

appears that a critical error occurs while opcua attempts to connect to an opc ua server and it is rejected. in this case due to incorrect security configuration. first reported at HA Community Forum

That said it shouldn't crash HA or prevent further loading. additional investigation required.
