Looks like the code needs to filter out empty string ip addresses

Please give https://github.com/amosyuen/ha-tplink-deco/releases/tag/v2.1.2 a try

Wow, that's fast, Almost, I guess (this is 2.1.2):

On closer look, it seems like the error is coming from the homeassistant DHCP component. It might be merging the state because both device_trackers have the same MAC. But I don't think there's much more I can do here. I would recommend filing a bug to home assistant core.

What also might be worth investigating is why your client has no IP address.

Thanks for your reply. A few things that crossed my mind:

• Does (the) TP-LINK (integration) assume that there is only one DHCP acting in the network? I.e. if the DHCP is lease is not from the TP-LINK DHCP server, is the IP therefor not available via the TP-LINK api?
• This error appears to have started to occur after firmware update 1.6.0 Build 20220525 Rel.48298 (coincidentally, that also about the time HA 2022.7.x came out)

The TP-Link integration has no assumptions about DHCP because it doesn't use it. All the TP-Link integration knows is the data it gets from the router API call.
