sorry for your disappointment. as it turns out, there are many, many reasons to buy such a device, one of them being to detect local phenomenon (mine blasts, for example). the device, itself, is a stand-alone product that can be used by its owner for any purpose(s) they want. the network, on the other hand, is a derivative product created when many, many devices are online, which is not a requirement for any owner of a Raspberry Shake to do.
thus, the network is, in fact, not guaranteed, nor so advertised in any way, to provide a “product” as a result of purchasing a Shake. in fact, event-reporting based on the Shake network does not require the purchase of a Shake product whatsoever, anyone can receive this information.
that said, it is our intent that as the network grows and densifies we will report smaller and more local events when the network conditions allow us to report accurate information. doing so before this were true would mean we risk reporting too many false positives, i.e., wrong and inaccurate information.
in the meantime, your device records all local events regardless, reported by us, anyone else, or no one, as your original post visualizes well. cross-correlating the local event catalog from the German govt., for example, to your own data-set will allow you to identify the events recorded by your device, that you can then share via your preferred social media platform.
and, with the new rsudp program recently released, you can even set up alerts in real time based on your individual data-stream, have you seen this? if not, please have a look at the post here.
