This timer, which is available under several brand names, such as Leviton and an appliance module for each device you wish to control, up to eight. Do NOT use lamp control modules. If you do, eventually someone or some power event will try to dim one.
Since you only named three devices, three appliance grade (with ground plug) mechanical timesr will plug into a semi-standard power strip. One with the outlets sideways instead of stacked on top of each other.
