OK, so to begin with, the overlaid icons on the map when using a Chromebook is a “feature” of running the HA app in ChromeOS. You can run most Play Store apps on a Chromebook, but not all of them behave as expected. The display is fine on Android devices. Probably not a priority unless you get lots of complaints (unlikely).
First part of your request:
- Running Chrome browser on a Linux laptop
- Home Assistant 2026.7.2
- ZHA Toolkit 1.2.1
1 Update Bindings Map card to 0.9.1
2 Restart Home Assistant and wait for all the end devices to become available
3 Open the dashboard with the Binding Map card on it. All devices are present, clearly displayed, no bindings. Message “Bindings never scanned yet”. The Bindings tab says “No bindings loaded yet”. The Devices tab shows all devices have been discovered, all marked as having 0 bindings.
- Click the Scan Bindings button. The scan (64 devices) takes 12 minutes to complete.
- The map still shows no bindings.
- Every entry in the bindings list is marked “Error. Target device no longer exists”. No mention of “partial”.
- In the Devices tab every device is now marked as having 0-16 bindings. These are presumably with the co-ordinator - the seven end devices on which I have set up bindings (Philips Hue dimmer switches) are shown as having none - presumably they were sleeping during the scan.
- There are two errors in the log, both repeated 15 times:

I’ll have a look at the developer console this evening.
Edit: After about half an hour (while I was posting this, in fact), the co-ordinator bindings appear on the map and on the Bindings tab.
Another Edit: Just realised that the “Hide coordinator bindings” checkbox affects the bindings page as well…
