Effect list returned to Home Assistant is not filtered for 2D

[thermseekr]

What happened?

In Home Assistant, when randomly selecting an effect using a template, sometimes WLED selects Solid instead of an existing effect.

To Reproduce Bug

Paste the template below in a Render Template Node in NodeRed.

{{ state_attr('light.light_name', 'effect_list') | random }}

Connect this node to a Debug and to a Call Service nodes. Inside the Call Service node, select turn_on as the service, select the relevant entity, and paste the expression below to the Data field.

{ "effect": msg.payload }

Every time the flow is run, the name of the selected effect will be shown in the Debug window in NodeRed and will be fed to the service call. Depending on the selected effect WLED will fall back to SOLID. Looking at the effects list in WLED one can see that in these cases the randomly selected effect do not match the name of any existing effect.

Expected Behavior

The name of the effects in effect_list should match the current effect names, so WLED will never fall back to SOLID.

Install Method

I'm inclined to agree that the list of effects in HA should be the same as shown in the UI, I'm not sure however if your technique of selecting effects at random is valid as I'm not familiar with NodeRed

[blazoncek]

Effect list is universal an includes all available effects.
What is shown in UI depends on filtering selection and capabilities of current configuration. This is UI action.

Sorry I'm a very basic WLED user and I was not even aware of the existance of 2D effects (oh gosh one more itch to scratch). I thought maybe the effects list in the home assistant integration was not updated to the actual effects list on WLED thus causing the problem. I'll try to check with the owner of the integration if there is something that could be done, maybe a toggle to enable/disable 2D effects reflecting what is configured in WLED, then disabling the selection of an invalid effect from the integration.

Thans for the replies, wish you all a merry Xmas and a happy 2025.
