What shelly to buy to install on the switchboard / electrical board?

  • Hello there,

    I bought an apartment from 1986 that came with some cool features but these sit on an old electric installation. While some part of the electric installation was changed recently, the heating is giving me a hard time.

    I'd like to measure the power that which switch on my electric board is spending, so I can identify potential peeks that are causing my electricity to go down. However, I have no idea what to buy from shelly.

    My electrical board is this:
