Have a nice new electrical greenhouse heater. Its set to automatically
start and stop with temperature.
So as to calculate power use and hence cost of greenhouse heating anyone
know of a good inexpensive system of recording the duration the heater
was
actually on?
Thanks


is this a 'hobby' or 'business'?
