Hi! I can do your project. After knowing the details of the project, I can comment further on timeline. What are the parameters to turn on/off relay? From where the parameter will come to Pi? Any webapp needed to manually control the relay or define the parameter? I have developed similar solutions like solar system, irrigation system. Thanks and Regards Maqsud
