Corrupted data in response, when changing a preset #3641
Description
What happened?
When requesting a preset change via JSON, I see some corrupted data in the response.
Preset changes successfully, but the response generates an error in Home Assistant, e.g.:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa6 in position 861: invalid start byte
It happens most of the times.
Very rarely response is correct.
It happens when trying to activate any configured preset.
To Reproduce Bug
- Use ESP8266_2M (Athom LS-4P in my case)
- Create multiple segments and presets.
- Change preset via JSON.
