PROBLEM DESCRIPTION

If I configure a RGB led controller and set saturation to 100 percent in web gui then tasmota reboots. when I set the color after reboot it reboots again.

REQUESTED INFORMATION

Make sure your have performed every step and checked the applicable boxes before submitting your issue. Thank you!

- [ ] If using rules, provide the output of this command: `Backlog Rule1; Rule2; Rule3`:
```lua
  Rules output here:
{"Rule1":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":0,"Free":511,"Rules":""}}
{"Rule2":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":0,"Free":511,"Rules":""}}
{"Rule3":{"State":"OFF","Once":"OFF","StopOnError":"OFF","Length":0,"Free":511,"Rules":""}}
- [ ] Set `weblog` to 4 and then, when you experience your issue, provide the output of the Console log:
```lua
  Console output here:
...
13:48:38.920 SRC: WebGui from 192.168.178.74
13:48:38.928 RSL: RESULT = {"POWER5":"ON"}
13:48:38.931 RSL: POWER5 = ON
13:48:39.585 CFG: Saved to flash at F6, Count 190, Bytes 4096

and then the reboot happens

TO REPRODUCE

_Steps to reproduce the behavior: Just play aroud with the sliders and you will see a reboot if the saturation is on 100 percent. I think it happens more often if there is a change from white leds to rgb leds.

Then don't do that. Seriously.

The point is that the hardware is most likely designed up to a specific power level, and overtaxing the power supply can lead to things like lacking voltage, overheating, or potentially fire.

You can use the command DimmerRange to config a safe range.
