<br clear="none">
If you want to compare a state code encoded as a string, you can
simply compare the std::string returned by AsString() with hard
coded strings, e.g.<br clear="none">
<br clear="none">
<tt> std::string charge_state =
StdMetrics.ms_v_charge_state->AsString();</tt><tt><br clear="none">
</tt><tt> if (charge_state == "charging")</tt><tt><br clear="none">
</tt><tt> …</tt><tt><br clear="none">
</tt><br clear="none">
If you'd rather use the old numeric state codes, there are utility
functions in the ovms_utils module for encoding / decoding them.<br clear="none">
<br clear="none">
As Mark wrote, you get the float value by the AsFloat() method and
can compare that directly to a float literal. We haven't added
comparison operators to the metrics classes yet, just assignment
(and that needs casts in many cases). If you'd like to add more
operators/types, go ahead.<br clear="none">

<div>Not required in v3. If you change a metric that needs
notification, the serverv2 and serverv3 will act appropriately.</div>
</blockquote>
<br clear="none">
And if you want to customize standard notifications, you can do so
by overloading the vehicle methods:<br clear="none">
<br clear="none">
<tt> virtual void NotifyChargeState();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyChargeStart();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyHeatingStart();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyChargeStopped();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyChargeDone();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyValetEnabled();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyValetDisabled();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyValetHood();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyValetTrunk();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyAlarmSounding();</tt><tt><br clear="none">
</tt><tt> virtual void NotifyAlarmStopped();</tt><tt><br clear="none">
</tt><tt> virtual void Notify12vCritical();</tt><tt><br clear="none">
</tt><tt> virtual void Notify12vRecovered();</tt><br clear="none">
<br clear="none">
If you want to add vehicle specific notifications, take a look at
the Twizy module (rt_notify).<br clear="none">
<br clear="none">
You can simply send a notification from any command output by
issuing MyNotify.NotifyCommand() (att: stack intensive) or send any
string by MyNotify.NotifyString(). There are also varargs versions
with "f" suffix acting like printf.<br clear="none">
<br clear="none">
For building strings from command methods, there is the StringWriter
class, that's a std::string that can be used as an OvmsWriter.
Example:<br clear="none">
<br clear="none">
<tt> StringWriter buf(200);</tt><tt><br clear="none">
</tt><tt> CommandStat(COMMAND_RESULT_NORMAL, &buf);</tt><tt><br clear="none">
</tt><tt> MyNotify.NotifyString("info", "charge.sufficient",
buf.c_str());</tt><br clear="none">
<br clear="none">
Best practice is to send notifications from within an event handler
(e.g. Ticker1), so they run asynchronously in the event task context
instead of blocking something.<br clear="none">
