Can you reduce the transmit power for a particular SSID in Unifi?

I got two Ubiquiti UAP-AC-PROs in my house. Great access points with enough connection strength to the footpath over road. Useful for when I'm at the neighbours house and can pull up cctv video to my phone.

But this can be a problem with my guest wifi network.

Often my neighbours new phone will connect to my network. Even with their device is 40m away and through three brick walls.

Currently set to auto transmit power for all SSIDs in Unifi controller.

No, You are setting the radio strength. It's not a per SSID thing. Why don't you just blacklist/block their Mac address? They won't be able to join then.

I don't want to blacklist them on my network.

They'll often come over in for a cuppa, and share things to the Chrome cast... Same as me around at their place.

Their phone Mac address is a rolling one.

Easiest fix is to look at using the guest gateway page option.

they would have to log in via web browser page to use your guest network..

otherwise, it much you can so given you are happy for them to use your network

You could try locking their device to the Unifi AP that’s furtherest from their house and see if that helps.
That would then still work when they do come over to your place.

Opinions are my own and not the views of my employer.

Hi why is your guest network open, I know you will say because it uses a hotspot portal to login, but why not add a wpa2 key, that way randoms won't connect (regardless if they complete the hotspot portal or not) and added bonus, guests traffic is encrypted.

I don't believe OPs network is open, they've allowed their neighbour to join and use guest network when visiting. Now their neighbour's devices are "roaming" onto OPs guest network when neighbour is at their own address as the signal must be stronger than neighbours own WiFi.

It's password protected.

Ok, stand corrected, as for limiting a specific SSID, perhaps managing beacon rates, other than that, no idea.

Switch off 2.4 on your guest network. Set your transmit power to low, or at least medium.
