Version of Easee integration having the issue?

0.18

Version of Home Assistant Core having the issue?

Anything in the logs that might be useful for us?

Additional information

As I can't configure, I can't debug?!

Has it worked before with the same hardware? My existing HA 2023.12.3 is working fine from distance, and I am not keen on making a reinstall since I am 380 km away from my Sentio sauna. It is probably something wrong with the setup of the serial port. It is almost impossible to debug without having access to identical hardware as yours. The code that fails is in the pysentio library. There is a short example of how to test and debug the library here: https://github.com/astrandb/pysentio

Thank you, Ake! Yes, it worked before. How do I test the library? Where to put the code?

astrandb commented 6 months ago

You need to test on the hardware that has the serial port. Are you comfortable with dev containers or creating python venv:s? If the answer is "yes" then go to the Linux prompt and do:

$ pip install pysentio

Then create a file e.g. test.py with the content from pysentio page and run python3 test.py.

If the answer on the question above is "no", I see no other alternative than waiting until the holiday period when i can try to reproduce the problem in my house.

You could also enter following into your configuration.yam and restart HA. It might generate som useful logs even if the integration is not properly configured. You could also try to set default to debug but that can generate a lot of data.

logger:
  default: warning
  logs:
    custom_components.sentio: debug
    pysentio: debug

I just played around a little. I am running my HA in HAOS in a virtual machine on a proxmox server. There I can "easily" test the library with the terminal prompt in the Studio Code Server add-on. And it works as expected.

Thank you so much for your support. The library test is working but I'm getting the same errors. I think I do have a connection problem or something else. Is there a possibillity to get the output of the controller somehow? Thanks alot!

astrandb commented 6 months ago

I did my initial tests with a laptop with a terminal program like putty and connected to the serial port. The Sentio interface is rather picky with delays between entered characters but you should be able to get readable error messages when hitting enter. Com port settings should be:

Baud rate: 57600
Data bits: 8
Stop bits: 1
Parity: No
