Hi there- let me see if I can answer your questions.
First off, using ONLY acu-link.com, you cannot create a public page really, you would need any specific visitors to have your MAC address to your bridge/USB console. They could then create their own account on www.acu-link.com
, and choose to "follow my friend's bridge" menu option and enter your MAC address and location. You, as the owner of the product, also have the ability to show and hide what your friend s can see as well- each individual widget has a sharing option under settings. This is all done for privacy's sake and to lessen the burden on the server, allowing for more frequent updates from all the devices.
Here is a link to our website that shows what the web page looks like: http://www.acurite.com/mybackyardweather
Really, the easiest way to share your weather publicly, is to choose the "Share My Bridge" menu option to stream your weather data over to weather underground (wunderground.com). This would allow anyone and everyone view your weather information easily. We felt that weather underground already did such a great job of displaying public weather information, we would focus on other features and simply provide a way to share the info with external sites. Makes for a more dynamic product with more flexibility.
I would advise you to check into your local laws and regulations regarding radio frequencies in your country, but technically speaking our RF will work anywhere of course. The packaged adapter is intended for U.S., but I'm sure you could find some sort of universal adapter for use in your country (output should be 4.5v DC 250mA with a positive tip).
I hope this answers your questions! Thanks!
