[Ovmsdev] Fwd: How does TPMS work now?

[Michael Balzer]

sharkcow,

the metrics shell command currently only supports getting & setting full 
values, i.e. all values at once on a vector metric.

Workaround: use Javascript:

sc ev 'm="v.t.health"; v=OvmsMetrics.Value(m); v[2]=80; 
OvmsCommand.Exec("met set "+m+" "+v);'

Not very handy that way. You can define a function for that in your 
ovmsmain.js:

function metricSetElem(metric, index, value) {
   vector = OvmsMetrics.Value(metric);
   vector[index] = value;
OvmsCommand.Exec("metric set " + metric + " " + vector);
}

…and then call it like this:

sc ev 'metricSetElem("v.t.health", 2, 80)'

Or you could add support to address single vector elements to the 
"metric" command.

OTOH, setting a metric manually is normally only needed during 
development though, so you already have artificial test values, why not 
simply set the whole vector?


Regarding reading vector metrics in a web plugin, that's straight 
forward: the vector is stored as an array in the global metrics object. 
Addressing elements is as simple as…

metrics["v.t.health"][2]

…and of course you can do everything you normally can do with an array.

Setting metric values from the web UI isn't a standard operation, so you 
need to call the "metrics" command for that here as well, e.g. via 
loadcmd().

Regards,
Michael
