Add api server

[Rasbats]

I work with plugins for the OpenCPN navigation program. Some of these plugins use a public api to provide tidal information.

Linking openrowingmonitor with a navigation chart to gamify rowing a river for instance would be of interest.

Could you give some ideas about where an apiServer could be inserted in the architecture? Has anyone attempted this?

Only minimal data like distance and time are needed from the metrics.

Wy not use the MQTT server for this? It provides this, as well as most other info out of the box. You will need a MQTT broker like Mosquito to be an intermediary, but several people use this already to interface ORM to their home automation system and Alexa. Perhaps another broker might provide an API out of the box, or OpenCPN has a MQTT interface (couldn't find that one via Google quickly). You can look at the MQTT interface description for more info. If you need help, please drop a line. I realize that our docs are not optimal yet, and your project sounds cool.

I am interested in how your setup is, as it would provide a pretty cool extension.

Thanks very much. mqtt is now working on my local network. The data is being published using mosquitto. Now to look at capturing the data with a C++ program.
