I'd like to build a water leak detection mechanism, and put a sensor under the dishwasher and a sensor under the kitchen sink, and notify if there's moisture detected. Any thoughts on the best way to do that? Three options in the tutorial section on the site:

1. Soil moisture sensor (not applicable)
2. Rain sensor
3. Water level sensor

The rain sensor, I assume, needs actual droplets on the face of it; so unless the leak happens right on top of the board, it won't trigger anything. The water level sensor seems very similar. So - any ideas on a better approach? Humidity might be a good option... or using a rain sensor but placing paper or other wicking material over the entire area to wick moisture towards the sensor?

Good to know. Do you just write the ID to the EPROM using a sketch that allows that and then write the node sketch to the Arduino, or do you assign the ID in the actual node sketch, or do you use MSYController?

Just trying to figure out the best/easiest way. :)

Thanks for the input!

Long story short: I'm setting up about 9+ PID sensors, 5+ temperature sensors, and 8+ door/window sensors, plus other stuff. I'm using the ethernet gateway and Domoticz.

It seems that when a sensor goes offline, Domoticz will re-use that node ID. That's fine, until I change the battery or bring a new node online and get the old ID, etc. Do most people hard-code the node ID in the EPROM, or have the gateway assign the node ID?

Also, MYSController seems pretty good from a troubleshooting standpoint. Any issue running that on the 'production' system, with MYSController bootloader, etc?
