Oh, @msebbe @AWI , I have a FastLED version with a decent web API and web interface available here: http://forum.mysensors.org/topic/2705/fastled-neopixel-ws2811-node-from-arduino-code-to-web-page-with-api
It's working pretty damn well Still working on my front end interface, since I'm not a designer (well, I am a 3d cad designer, not web dev).
Oh, and if you knew my controller's name, you could communicate with it via TOR. Just like corporate solutions, I can communicate and control my gateway from anywhere in the world!
@jvdk I agree with the point made by @evb , why would you want to wire connect the ultrasonic node rather than the usual radio connection ? You are adding levels of complexity and power demands for what reason ?
My ultrasonic water tank node (pro-mini+rfm69) is now 2 years on the same 2xAA batteries sending in levels every hour (RTC), the only problem encountered - condensation forming a drip on the face of the ultrasonic head during very low temperatures.
following this thread loosely.
I have the following sensors and they seem to be accurate to some degree:

and they are much easier to work with Arduino compared to Watermark stuff. Anyone agree?
