SOTAwatch / RBNhole / APRS2SOTA / SOTA2APRS flows

The way SOTAwatch, RBNhole, APRS2SOTA and SOTA2APRS interoperate can be difficult to understand.

I tried to show the flows on a mindmap in the hope it will clarify things for the people who are interested in the technical details.

Please let me know how to improve it if you feel it could be made more clear.

Some background information is also available on


Thanks for the summary.
Maybe the API and SSO system for Sotawatch3 should be included as it is relevant both for RBN and APRS2SOTA

Thank you. Added.

APRS2SOTA is bi-directional - APRS users can get spots and alerts from the SOTA API.

Thank you. Updated.
