M30 configure yaml for ESPhome

[stephane]

Dear Administrator,


I am using the yaml you've provided, but the values shown in home assistant are wrong
For example:
M30_1_current_1 = 2.606 A
M30_1_ voltage   = 235.3 V
M30_1_ watt_1   = 6099 W 
also, with the same current, M30_1_ watt_1   sometimes falls to 144 w

None of both values are correct, and this is the same case for all of the 30 channels.

The product is totally unusable like this

What can be done to get some correct values?
