Hello @dbemowsk ,
For now just if there is water in the boat, we have two bilge pumps at the bow and stern. Our boats are wooden boats (circa 1950's) and when we are not at the cottage I want to ensure water is not filling up the boat (even though we do put the boat on slings to be doubly sure it won't). Secondly I want to monitor that the battery is receiving a trickle charge (again to ensure the bilge pumps don't drain the battery).
And third and last...seems like a fun way to get the kids involved in building an IOT project with me! 
I'm also hoping that as we build out this little project I can build out more IOT projects based on this initial setup.
Thanks!
