'In use by' is not showing anything (groups)

rasmus.christiansen · April 10, 2026, 12:30pm

I have some devices that are bundled in groups and these groups are then used in apps.
Previously I could see where these devices are used in (like groups and apps), but now the list shows nothing:

They are part of a group:

Which is used in an app (Rule Machine), for example:

Other devices (also Ikea) have no issues showing which apps (eq. Rule Machine) they are used in:

My Hub C8 Pro is on latest firmware, all packages are fully updated and hub rebooted several times.

What am I missing?
Why can I see the content of 'In use by' for some devices but not others?

Can't say why, but I just checked some group devices I have and they all show apps in the "In use by". So it's working for me , weird.

Reboot hub maybe?

My Room Lighting groups are also displaying apps they are used in on the In Use By tab.

@terminal3 - are you using the legacy Groups and Scenes app or Room Lighting to create your groups? @rasmus.christiansen is using Groups and Scenes.

@rasmus.christiansen - As long as you're rebooting, choose the Advanced options in the reboot dialog and select Rebuild Database.

Using Groups and Scenes app.

I had this issue and someone (sorry can't remember) said check conditions in rules. They will show "in use by", but not in the rule itself. In my case, I had a condition that was no longer used, but referenced the device.

@jeff.turner.reid thanks for the work around.
I see it as a bug because there should not be any conditions for, when showing then pane 'in use by'.

Bug or just an obscure issue. It is technically in use but not very obvious when you look.

Is that the only rule that Group is used in?

If so, have you tried creating a different test / dummy rule that uses that Group?

That may help distinguish if the issue is perhaps somehow related to just that one rule, or is something bigger.

This is definitely odd though!
