HA Compatible Energy meters

Hi all,

i am based in Thailand and in my new house i am building i want to add some power meters to monitor power ussage.

I have 3 consumer units - 100a, 50a and 50a.

i have been looking at the Shelly EM Gen 3 - but see they are rated to only 50a - is it ok to run one of these on the 100a consumer unit or are there any other alternatives?

regards
