<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">I’ve got a proof-of-concept javascript running on my pc, including some preparation http calls to get the right magic token and the charge-box indeed receives the command and stops charging.<o:p></o:p></p>
<p class="MsoNormal">But am now having trouble translating this in javascript that is accepted by the OVMS module…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I also have the beginning of a OVMS script, triggered by ticker.60, that basically does:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:36.0pt">var charging = OvmsMetrics.Value("v.c.charging");<o:p></o:p></p>
<p class="MsoNormal"> var bat_soc = OvmsMetrics.AsFloat("xnl.v.b.soc.instrument");<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:36.0pt">if (charging === "yes" && bat_soc >= 80) {<o:p></o:p></p>
<p class="MsoNormal"> stopCharging(); // <-- this still fails…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> // Note: OvmsVehicle.StopCharge(); is not possible on Nissan Leaf (only StartCharge is)<o:p></o:p></p>
<p class="MsoNormal"> }<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It would be really nice if I could get the OVMS module to trigger the stop charging command by itself. That would give me similar functionaliy as what this guy did using a CarLoop device (<a href="https://www.mynissanleaf.com/viewtopic.php?t=23741">https://www.mynissanleaf.com/viewtopic.php?t=23741</a>).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If it is not possible, then I need to revert to running a script somewhere on a server, that will periodically keep an eye on the OVMS metrics and then triggers the stop.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
