Request - Add Error and Warning Sensor

[holdestmade]

Thanks again for this integration, it's been working great

Looking at the API there are error messages in the read, any chance you could add a sensor with any warnings or errors ?

The ones that look useful are below

E02-Overheating Overheating is occurring
E03-Dry heating Dry heating is occurring
W03-Long heating Unexpectedly long period of heating
