TP Link L530 bulbs not transitioning properly

[flyinghier]

The problem

When I call the light.turn_on service on by TP link Tapo L530 bulbs, they ignore any transition instructions. I am able to successfully transition another light using the same integration which is a Kasa KL135 bulb, however the L530's are not transitioning as expected.

core-2024.7.2

Alas, only kasa-branded devices support defining a transition for individual commands, so we should remove the transition from supported features for tapo bulbs like yours.

For tapo devices, you can either toggle smooth transitions on and off, or adjust the transition time for both on & off separately. You could use a script to adjust those values prior adjusting the light settings to simulate different transition periods.

I'm having the same issues with L530 bulbs 2 off. But I've working with Tapo as well over them dropping off the network with 2 issues I have 1 when powering off and back on they come on as 100% white 2 sometimes they lose there programs in the Tapo app on at sunset and off at set times. Tapo is causing issues in HA on timeouts. It did do an update 2 days ago but no different. Update - 2 bulbs above are hardware 1 - a 3rd L530 I have is hardware 2 and don't seem to have the issue.
