New Zealand has a population of 5,000,000 (5 million people). Now assume that there are 5 people per household. That is 1,000,000 households (1 Million). Now if 1/10 households had a Smart Weather Station, that would be 100,000 stations. Now if the stations cost about $200 USD apx. Then to cover New Zealand (at least the residential areas) would only cost 100K x $200. $20,000,000 ($20 Million). Now for the benefit that that would have on the country (if 1/10 households were happy to purchase a Weather Station, I think currently in NZ, it's less than 1%), having perfectly precise weather data in virtually all populated areas (and since multiple stations, rouge stations would easily be noticed) in NZ for the cost of only 20Million does sound pretty cheap for the amount of benefit it would provide. And let's say since so many weather stations were being mass produced and bought, it only cost $100 per station. And let's say only 1/100 households got it (apx 1 per street), which would still be pretty precise data. The total cost could be reduced to $1,000,000 instead of 20 Million. Anyway just some thoughts.
