How apply regexp for validate number? How to change message for required?

I’m trying to validate a number field.

    Yup.object().shape({
        temperature: Yup.number()
                        .min(0, 'Minimal value 0')
                        .max(30, 'Maximum value 30') 
                        .matches(/^([0]([.][0-9]+)?|[1-9]([0-9]+)?([.][0-9]+)?)$/, {
                            message:'Inccorect format. Example 25 or 25.1',
                            excludeEmptyString: true
                        })
                        .required('Temperature is required. Please enter value from 0 till 30')
    })

I got error if apply matches for number,

and I can not to change message for required. I got default message.

This is how I tested for number and for regex; I used mixed and wrote custom tests.

const schema = yup.object().shape({
  price: yup
    .mixed()
    .required('Price is required')
    .test('type', "Price must be a number", value => !isNaN(value))
    .test('validDollar', "Price must be a valid dollar amount", value => /^\d*.?\d{0,2}$/.test(value)),

@zhrvdns Would you mind showing how you accomplished this? And thanks @jquense for this awesome validation tool.

Thanks!
