Hi Dave,
My question is; how expensive is it in terms of recurring costs to make available my weather station's data available remotely? How much data does one of these things use if it updates, say, every 15 minutes?
I have my VP2 set at 10 minute interval so have about 17 days before it starts to over-write on the logger.
The ongoing cost after you have your hardware would be:
1. To upload to Weather Underground, CWOP, PWS, WOW, etc. it would be nothing ($0.00) beyond what you would pay for your internet service to provide continuous service, if you get free/donation ware software like Cumulus. A donation to the developer is encouraged but not demanded.
2. To also upload to your website it would be the above plus the annual cost of a domain name - less than $20, and the cost for your webserver provider - i.e. GoDaddy and less than $100 annual depending on which plan you select.
3. There are options and alternatives such as paid software and other things you might wish to add and use - i.e. webcam, lightning detection, ...
Not an expensive hobby beyond what you invest in the equipment you decide upon. The expensive part is the amount of your time you might end up using to enjoy your station
