hi

does anyone know of a solar hot water controller that also has built in data logging and the ability to be hooked up to the web so info can be viewed online in real time?

thanks

You mean you would like to buy one?

Or build one?

Can do either.  

Best to start with spec-ing what you need.

For example, as a start --

Inputs:

Monitor ambient air temp

Monitor water temp from x to y

Monitor pressure

Monitor T & P valve

Flowmeter

Outputs:

Valve/Solenoid Controls

Pump Controller

Data channel output

Radio or hardwire link

I was going to get this controller because it has ethernet so it could get

linked directly from a web page but 1 reviewer only thought it was so so for

this (ran the solar system good)

does anyone know of other controllers that have ethernet with automatic graphing

of stats

thanks
