indoor greenhouse

I have indoor grow tent, with multiple citrus trees, It runs an exhaust fan, 4 air moving fans, 4 lights, 2 heating pads, and an irrigation pump, I currently run most of the items off of a wifi power bar (geeni surge 6) and the exhaust fan runs via its own controller with temp and humidity settings. The irrigation pump is supposed to run off of a wifi based application (the app no longer exists) I am looking into the idea of getting a raspberry pie and running the entire system off of that with some programming. I would have to regulate on/0ff times for lights and exhaust fan and also integrate a run cycle for the irrigation pump. If anyone has any insight into this tye of system please lets start a conversation
