No. You require an a.c. output. That one is d.c. @dBC & @Greebo recommended this one 240VAC to 12VAC Transformers - #6 by Greebo a little while ago.
The optical pulse sensor will give you an accurate pulse count of energy - historically, after that packet of energy has been taken. It won’t tell you the present power consumption. Nor is it likely to tell you anything about exported energy.
The plug wiring is in the Resources section, under the emonPi heading. The pulse input is D3 (pin 6) and the temperature is D4 (pin 4).
