Hi @djdevil please add you configuration here thx

[jazzarmac]

Hi @djdevil is this what you're looking for

alert card config.txt

[djdevil]

Can you explain exactly when it happens? When the music notification is active?

[jazzarmac]

hmm playing music now and it seems fine . I have some heavy template stuff in there relating to SEPA , and MET office warnings, I had been playing about updating them , wonder if that had something to do with it. I've also don a force refresh on the browser and HA App so maybe that's impacted it as well

Hi @jazzarmac — glad it's behaving now!

The most likely culprit was the browser/app serving a cached version of the JS after the v1.3.4 update, creating a mismatch between the old CSS and new render logic during card transitions. The force refresh cleared that.

One thing to watch in your config after v1.3.4: your thermostat alert uses conditions_logic: or, which had a semantic bug fixed in v1.3.4 (#168). The old behavior was:

show if HVAC ≠ idle OR thermostat ≠ off

The corrected behavior is:

show if HVAC ≠ idle AND thermostat ≠ off

If you intended either condition alone to trigger it, you'd need to restructure — but the "AND" version is almost certainly the right one here (don't show the heating alert when the thermostat is switched off).

A couple of minor config notes:

conditions: [] on your music alert is harmless but has no effect — safe to remove
entity_filter: "Media " has a trailing space — worth double-checking it's matching the right entities (works if your entity IDs contain "media ", but may filter out things you expected to include)
If the strange transition behaviour comes back, a screen recording with the browser console open (F12 → Console tab) would help pinpoint it. Feel free to reopen.
