Skyconnect V1.0 stopped working after last update to HA

mackra · November 27, 2025, 9:28am

Hi there! I updated to latest HA core on my virtualized HAOS and my skyconnect V1.0 stopped working with error that serial port is locked by other application. Checked logs and this is what i found about skyconnect.

Seems like there has been some changes on .py files that retursn unkown skyconnect product name?

has anyone else had this problem or found solution to this? everything works fine when i return to my latest back up thats from version 2025.9.4

Hello

My guess is that you are using the short URL for talking to this port and not the longer serial/by-id one. The actual port can change internally at boot time, where the longer URL is linked directly to the device.
The TTY ports can sometimes change internally, so it is suggested to use the /serial/by-id/ URL that always talks to your dongle by serial so it is always right.
You can find out that that is by using:

and looking for it under all hardware, something like this:

Hi there. Im still on older version but checked that out on it and seems like im using that serial/by-id/ path atleast on this. Version

Il test later to update again and test it out.

Sir_Goodenough · November 28, 2025, 8:17pm

Your ZHA or Z2M software has to be addressing the longer URL. That message above was just telling you how to know what your longer URL is so that you can tell whatever application is talking to your dongle a better way to find it.

mackra · November 28, 2025, 8:40pm

Oh yes. haven’t tested update yet but checked that ZHA is using long url on older instance.

Il check that on newer one after i get my wled and shelly blu buttons to talk to each other with dimming/brightening :'D il make another topic about those soonish if i can’t figure few things out…

okay. tested again with new home assistant core. this is from system info it sees skyconnect

This is error:

And it only lets me reconfigure current router and just gets cannot connect to router error.

And this is in the logs
