Is it possible to make ethernet shield control inputs/outputs over LAN? A website that has buttons for on/off etc?
What would be smart way to control 230V mains with 5V arduino? SSR isnt possible because it has to be NC-relay. If arduino fails etc that relay has to conduct.
Use a professionally designed, constructed relay solution, unless you need very rapid on/off switching.
(Thank you! The draft for that has been languishing in my "to do" pile for a long time! You inspired me to get it Out The Door!)
Why arduserver and not arduino + ethernet shield?

this mains socket type aint working for me. Its not gonna be a socket device, its a fixed device, house heater water pump.
How about a small 5V relay to control SSR relay? That way i could have NO operation and i think SSR would be right one for this?
Thre are various relay boards available that are made for use with microcontrollers, parallel ports, etc.
Hmmf.. I mean would it be best to use 5V relay to control the input of SSR? that way i can get NC operation. I dont need ready made 8 relay boards for that. I can make my own board with one relay. I just want to know are there any better way to do it?
Arduino controls 5V relay that switches SSR which is connected to AC motor.
I can make my own board with one relay.
Yes... but can you make one that will be safe at those voltages?
If you don't find a relays controlled with the 5V , you can also take one controlled at 12 V and use it with a BC337 transistor that could work as a switch.

Did u understand ?
Seems like it will be arduino controlling 12V or 5V relay that controls this
Or someone got better?
