Thanks for the prompt response. You are right, there is box on the side to provide the 24vac.
I do have the outdoor enclosure for generation 2also. Actually, I live outside the USA and here the voltage is 220v 50hz. I thought instead of buying another power adapter and wiring the enclosure box to the main power supply, since everything is already installed, all I have to do is cutoff the end of the power supply provided, wire it to the 24vac wires and Plug it in the rachio and that's it.
Is that possible?
