Log entries - Help

I’m getting some entries in my hub log and I’d really like to get rid of them to ease other troubleshooting. They look like they are from Hue but I just can’t figure out why they are there. I’ve removed any unused Hue bulbs (I have also removed them from Hue). The only Hue items I have defined in ST are the Hue bridge and active bulbs. If I load Hue Connect there are zero bulbs to add to ST.

As for the log:
Five entries appear every couple of minutes and they look like this:

Contents of each entry look similar to this:

devicetype:04, mac:0017882339AA, networkAddress:C0A80595, deviceAddress:0050, stringCount:04, ssdpPath:/description.xml, ssdpUSN:uuid:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, ssdpTerm:urn:schemas-upnp-org:device:basic:1, ssdpNTS:

Anyone have any ideas on what might be causing this?

My Hue bridge has a confirmed network id of: 0017882339AA

Thanks in advance for any help!

I have just discovered the same and also has no clue what is it.

No idea how I should proceed, so far.
