[Ovmsdev] Open Charge Map

[Lee Howard]

If I understand correctly, the GPS data is sent from the module in the 
car encrypted through the server to the handheld app.  (Correct?)  Or 
maybe that was outdated information that I read (README files in the 
code).  Hence, I do not understand how OCM would reliably "pull" data 
from either the module or the app.  A "push" from module to OCM seems 
burdensome and inappropriate.

So, if the GPS data is encrypted all the way from the module to the app, 
then I can really only sensibly imagine the app pushing data to OCM.

I must have misunderstood or read outdated information in the READMEs... 
because it seems much more-sensible for OCM to be communicating with the 
OVMS server... whether it be a push or a pull.  But... if the data is 
encrypted passing through the server... then that's out of the question.

And, I presume, then, *that* is where you are looking for help: 
implementing the authentication model on the OVMS server. (?)

Thanks,

Lee.

My own personal preference is just to provide an api to either PUSH or PULL the data, and the reason for that is I don’t want to be extending the server code to support ten different third-party APIs. That said, I did suggest a PUSH option in the original RFQ, and the thinking behind that is we can format a URL+formdata with parameter-substitution (based on server.conf settings for a particular provider - no code) and just fire it off. I see no problem with a single API key for OVMS to submit to such an external service. For ‘user credit’, it would be nice to have an option where the user could enter an optional username+pin for each service, and we can provide it as part of the PUSHed/PULLed data.
