Signal K: Adding Keys / new sensor

[PaddyB]

Hi folks!

I'm currently playing with Signal K the first time on a more serious level and I am starting to really enjoy it.

I also tried the API to read some values, also to change some values after authentication. 

As I have a serial protocol which is not supported by OpenPlotter, I need to run Node-RED to grab some UART data and create some jsons based on the information. In this case: My solar charger's information, current, power etc.

Long story short: I would like to add this data into Signal K and as I am able to modify keys using the API, I could do it. However, I asked myself if I can create own keys and a new type of data.
The API can't create new keys - is there any way to do this with Signal K directly?

Thanks!

Node red will do that for you, send the value as  msg.payload  and the key as msg.topic  to a signalk-send-pathvalue node. You can try using an inject node which lets you set those.

Or send a signalk delta json with the new keys in it & signalk will create them. siggK does it all for you 

Copy & paste this into the data fiddler & click send to server then have a look in the data browser >>
