iot-solar allows to use ssb to interface with solar mini/microgrids allowing to have a secure way to control them.

The general context is

AYO, BAAKO, CHIKE, DESTA and EKENE (*1) are the members of a small community powered by solar energy.
Each member have its own laptop, so there's no central servers to make backups, and they want to manage all the solar energy stuff and keep a track of all things done there.
For this, the community creates an special SSB network only to manage the microgrids. The community uses SSB to communicate and share things as usual:
- discuss about what needs to be done
- votings
- share manuals, schemas, etc...
- anotate operation on solar panels
but also wants some extra functionality
- allow grid to be operated remotely, via admin feed subscription commands the device will process
- allow grid to to generate feed about its status, by generating a message each day about its performance
iot-solar, is the bot that is installed in the microgrid allowing interaction

command line

iot-solar setup - creates an identity and setups the database iot-solar admin add @id - adds a friend (can send commands) iot-solar admin remove @id - removes a friend (cannot send commands) iot-solar report filename.txt - generates a post with the report iot-solar action action.txt - generates a post with the action (self-consumed)

config.toml

netid = # networkid to use actionpath = # executable to call when an action is triggered via special admin feed

current admins

filesystem

own feed
- admin feeds

api (actix)

POST /api/admin/add/ @id POST /api/admin/rm/ @id POST /api/admin/report in body is the report content POST /api/admin/action in body is the action content
