Hi,

Been using this for a while however noticed today while looking in my logs the following error spamming the logs:

As you can see 1.5k+ instances of this error over the space of just over 24 hours.

Integration seems to be working though (I only use it for device_tracker as the APs are in bridge mode).

I know what's causing that... I'll get it fixed and let you know when it's done.

Well, hopefully that was quicker than I thought it might be.

I've just pushed beta version 2024.2.1b0. Would you be able to test that please? I don't see the error here so difficult for me to test it.

Will give it a try shortly :+1:

All seems to be fine now 👍
