Google Assistant does not understand “Outlet2” or “Light2” Types. My guess would be
Switch fan "enchufe 2" <poweroutlet_us> { gpio="pin:17 activelow:yes initialValue:low" ga="Outlet" } (gBedroom)
Switch night_light "Enchufe 1" <poweroutlet_us> { gpio="pin:27 activelow:yes initialValue:high" ga="Outlet" } (gBedroom)
Switch exhaust "Luz 1" { gpio="pin:23 activelow:yes initialValue:high" ga="Light" } (gBedroom)
Switch light "Luz 2" { gpio="pin:5 activelow:yes initialValue:low" ga="Light" } (gBedroom)
Using code fences here shows us exactly how your configuration is spaced. The type of quotes look wrong too, but that may have been just the forum messing things up.
