I already have an arduino and ethernet shield. I want to have ST show status of my sump pump. Can I do this without the official ST shield?
Something like having the arduino post to a web URL like: http://SThubip/sumppump/status=on|off
Also is there a way to create a small graph or keep track of data? It would be useful to know if the sump pump ‘duty cycle’ is unusual (100% or 0%) so being able to look at data by hour would help.
I don’t have ST yet but about ready to buy one. Want to make sure I can make it do what I want before I spend the money
Also plan to use arduino to keep track of garage doors and then turn on a light in bedroom if garage door is open.
