Thought you guys may be interested in this BlueTooth enabled, programable fuse block and power distribution module. I've been following the development of this on another forum and there's been a ton of thought that has gone into the unit.
Check it out!

I'd love to hear what ideas you have for it on the boat!
two questions
1) It was written "Brownouts as low as 5V won't reset the device". On some boats, starting the engine creates brownouts. Possibly even under 5 volts if there is enough on the outputs of this product. What do you mean reset the device? Ideally the device would remember the current state when the brownout ceases, and not "reset".
2) On boats, there are two features you might want to consider, understanding you are able to measure the electric current on each circuit.
Bilge Pump - Measure the total run time that current > 1/4 amp and display that on the smartphone. Have an ability to show total last 24 hours and last 30 days. (e.g. bilge pump was on 6 minutes in last 24 hours might be normal, where as 30 minutes is a problem). Have the ability to count how many times the bilge pump was on in last 24 hours and last 30 days. Have an ability to reset to zero. E.g. when the bilge pump is running,
Fresh Water Pump - Same as above, But Maybe allow for a countdown. E.g. everytime I fill up the water tank I have 90 minutes of water.
Lights - Lights on boats break. Allow a circuit to be designated a safety light, and indicate when the circuit is turned on, but no current is being drawn, there is a problem.
