Home Assistant - Wake On Lan

Hi! I am using Home Assistant in Umbrel and i can´t use Wake On Lan correctly (my computer doesn´t turn on). I have these:

switch:

  • platform: wake_on_lan
    name: alonso-System-Product-Name.local
    mac: 3C:7C:3F:16:E9:98

There is something wrong with my code? Thanks in advance

PD: I have a Wake-on-LAN app on my phone, and it successfully turns on my computer.
