Device Tracker firing all the time

Configuration
1

I’m using both the dd-wrt and bluetooth device trackers in HassIO. Recently, my presence detection is starting to do some very strange things.

Home assistant keeps logging presence changes, from home to not_home, then back to home, on a repeated basis, for all of my devices that are actually continually home. This is causing all sorts of havoc with my automations, making my lights flick off then back on, starting and stopping my music, and so on.

It’s also disconnecting and reconnecting to my Google Play Music desktop player intermittently, so I’m not able to control things consistently. (I’m also not able to resolve this problem with Plex certificates, but the Plex component appears to be working properly).

This only started happening after I reformatted my main PC yesterday. HassIO is running on its own RasPi3, which I haven’t touched.

Here’s the log from Home Assistant.

It turns out that having both bluetooth and dd-wrt tracking on at the same time is causing this issue. Still not sure why, though. For now, I’ve disabled bluetooth tracking, but I’d really like to have it enabled, as I’m using a couple of wireless access points across my apartment, and when I spend too much time away from my main router, HA thinks I’m not home.
