Custom (confirmed working hardware

Steps to reproduce.

Just running the lightbulb example... maybe its related to the esp32 needing to wait for tasks i have tried to use both hardware timers on and off same result

Build Logs.

this is the error when we try to change state interestingly it seems once its gets past the first few seconds of booting it works more reliable but as soon as the LEDC_FADE_TOO_FAST shows in the logs its no longer responsive and the light needs to be power cycled

What frequency did you set for the PWM? Can you try disable the hardware fade and test again?

(Top) → Component config → LightBulb Driver Config → Drivers
[*] Enable PWM interface
[ ]     Use hardware fade API
...
...

I'm only using it at 150hz and I have tried that

This is a bit strange, as I can't reproduce the issue in my environment. It might be related to the application code. Could you provide a debug-level log?

[ThatBigPrint]

I'm in airport at the min... Is it true on the esp32 including the d4 I can't call other code until the fade is finished? Or can I pin this to separate core? I've noticed sometimes dependant on connection time it interups JSON parsing
