Error if two nodes are active at can bus #33

Joezi79 commented 3 years ago

I have a problem with pyblnet and home assistant. I am getting the following error message:

Traceback (most recent call last): File “/usr/src/homeassistant/homeassistant/setup.py”, line 213, in async_setup_component result = await task File “/usr/local/lib/python3.8/concurrent/futures/thread.py”, line 57, in run result = self.fn(*self.args, **self.kwargs) File “/config/custom_components/blnet/init.py”, line 102, in setup data = fetch_data() File “/config/custom_components/blnet/init.py”, line 98, in fetch_data return hass.data["DATA{}".format(DOMAIN)].update() File “/config/custom_components/blnet/init.py”, line 146, in update data = self.blnet.fetch(self.node) File “/usr/local/lib/python3.8/site-packages/pyblnet/blnet.py”, line 91, in fetch direct = self.blnet_direct.get_latest(self.max_retries)[0] File “/usr/local/lib/python3.8/site-packages/pyblnet/blnet_conn.py”, line 304, in get_latest self.get_count() File “/usr/local/lib/python3.8/site-packages/pyblnet/blnet_conn.py”, line 84, in get_count checksum) = struct.unpack(’<5sB3s3sB’) TypeError: unpack expected 2 arguments, got 1

I have two network nodes at can bus. Here is my yaml config ‘’’ blnet: resource: “http://192.168.178.222” password: 12345 use_web: true use_ta: true web_port: 355 ta_port: 40000 can_node: 32 ‘’’ It works if I set use_ta to false. Does anyone have an idea to overcome this situation?

As described in the README, the use_ta option is disabled by default for the simple reason that it causes exceptions like the described one. Please disable it to avoid issues.

Ok. Thank you very much for your fast reply. I enabled it in the hope to get some more values like heating quantity.
