I don't think that is far fetched at all, in fact every commercial setting period should at this point(since usually no one is on site to do anything, and computers are more accurate) have a minimum of a rains sensor installed and verified it works every year, maybe twice per year check it. It would cut down a super large amount of waste. However, it is a very popular and requested device by clients of ours. It only makes sense and is generally a cheap investment overall.
all is fair in love and grass!
Man, it smells like sheet, do you smell that!!
