3 Phase and Single Phase Timer Switches with web interface

Projects General Guidance
1

Hi,

I have a project to start- I have around 15 pieces of equipment that can be of single or three phase supply. I would like to control the time and day each piece of equipment powers up via a central web interface for all equipment, replacing the use of mechanical timers. Any advice on this project welcome. I have past experience in programming in C with microcontrollers, but its been a few years.

Thanks,

Please post some specifications like current, voltage, budget, etc. and physical layout (are the equipment located how close to each other and the controller?).

It looks like you skipped over the introductory guides. Why?

How do You intend to detect machines being on or off, being turned on or off?
Tapping the on and off buttons might be a way.

Thanks for your reply. Max 8 amps, 230v, budget less important as reliability. Location is to be within 1m of equipment
