Serial connection over TCP not working? #46

Open Flink opened 1 week ago

Flink commented 1 week ago

Not wanting to hijack an existing issue (like https://github.com/RainerStaude/hass-becker-component-plus-pybecker/issues/39), so opening a new one :sweat_smile:

I tried to setup my becker USB dongle with a small serial over TCP server to be able to use is from anywhere on the network. It actually works, if I use the pybecker lib directly on the command line, I can move my blinds. But when I try to use the HA integration, it doesn’t work. On the server side, I can see there’s a connection stuck in ESTABLISHED mode. And no commands get through. HA also complains with this in the logs:

It seems the integration tries to open a blocking connection to the serial server instead of connecting only when sending a command, or something similar?

Let me check that. To be honest I have never checked the connection over IP, but tried to keep it in the integration. Looks like you're probably the first one using this. Is there a good guide available how to setup such a TCP Server? Just a simple loopback would be perfect to test this. And of course I need some time on a rainy weekend 😉
