Suitable CT clamps for M30

[Linus68]

Hi,

current is now working well.
But the YAML has some failures.

M30_CT bl0910_1_voltage: 15.145.419,0V
Temp and frequence are Unknown
Which register they have?
Have you a list with all the register.
As I see the file is unsignet, that means it has no negative values for the power
