SSL Handshake error after installing integration

[MiteZZ]

Did you read the instructions?

• [X] I have read the README.

The problem

I've installed the integration, and that worked. It recognized the reader, but no values where read ( maybe due to misplacement of the IR reader) But when I restart homeassistant, I'm not able to connect to it anymore. I'm getting a SSL handshake error. If I un-plug the USB of the reader out of the NUC 11(I'm running a Genergic x86-64 image) and power it, homeassistant works again. When I connect a monitor to it with the USB plugged in, I see that homeassistant starts up, but that's it, no connection possible. Also with different clients or external link.

Is there something I've missed that I'm doing wrong? Any ideas?

thanks!

Please attach the diagnostics file and also the home-assistant.log and or home-assistant.log.1 file

I've added the files to the original post. I needed to install the integration again and restart HA for the issue to come back.

I downloaded the logs after that with all the USB's unplugged.

Thanks, but I need the diagnostics file that you can get through Home Assistant, see https://www.home-assistant.io/integrations/diagnostics/

There is no SSL Handshake error in your log files, so I guess that error came from another integration?

I see you configured the integration to use /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_AB6AZ0PB-if00-port0 but that doesn't seem to be available:

You've also seem to use the exact same device for DSMR and that can't be right.

So I think you need to sort out your serial devices, you should run

ls -lah /dev/serial/by-id/

To list what is available.

[MiteZZ]

Okay thanks I'll give that a try and see what happens. if that's not the solution I'll post the diagnostics file.

Thank you much for your help so far!

[golles]

Did you manage to sort out the issue with your serial ports?

[MiteZZ]

Hi Golles,

I think so, I've just had the time to try it. It seems that I'm not getting the error though. I did not get any values back from the Kamstrup but I'll try the allignment on the heatexchanger itself for that.

Thanks anyway for you good help! I'll keep you posted.

[MiteZZ]

Hi,

still no values sadly.

Hereby my diagnostics file and the logs!

config_entry-kamstrup_403-76e5daa252fa6f72b6d19f4d8d646bba.json (1).txt home-assistant.log home-assistant.log.1.txt

If I check the IR-reader with my phone's camera I see that one of the led is blinking so that works.

[MiteZZ]

Hi all, I'm now getting in the log:

2023-07-17 14:32:01.420 DEBUG (MainThread) [custom_components.kamstrup_403] Start update 2023-07-17 14:32:01.420 DEBUG (MainThread) [custom_components.kamstrup_403] Get values for [60, 68, 99, 113, 1001, 1004] 2023-07-17 14:32:02.421 DEBUG (MainThread) [custom_components.kamstrup_403.pykamstrup] Rx Timeout 2023-07-17 14:32:02.421 DEBUG (MainThread) [custom_components.kamstrup_403] Finished update, 4 out of 0 readings failed 2023-07-17 14:32:02.421 DEBUG (MainThread) [custom_components.kamstrup_403] Finished fetching kamstrup_403 data in 1.001 seconds (success: True)

any ideas what the Rx timeout could fix?

thanks!

[golles]

First of all, could you ensure the head is connected correctly to the meter, this is very tedious. I guess the default timeout is too low for your setup, you should increase that to a higher number, eg. 2.0 see https://github.com/golles/ha-kamstrup_403#configuration

Yes it is positioned correctly. I didn't get any values so I went back with an raspberry pi setup that pushes the data via MQTT and that's working now. No clue why the integration doesn't work.

Thanks for all your help though!
