it's generally a bad idea to have polls running just based on the
client connection status. Clients may be connected all the time,
e.g. if users attach some API pollers or set the App to persistent
background operation (which is necessary for widgets or tasker
scripting for example).<br class="">
<br class="">
You should only enable polling when actually necessary to perform
some user requested action, or to monitor a drive / charge session
of course.<br class="">

We've got an explicit "wakeup" command users can call to tell the
module to wake up the car. That needs to implement some timeout to
put the car back to sleep if it doesn't do so by itself.<br class=""></div></div></blockquote><div><br class=""></div><div><br class=""></div><div><br class=""></div>Sounds like a better idea IMHO. </div><div><br class=""></div><div>Tracking issue is <a href="https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/275" class="">https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/275</a></div><div><br class=""></div><div>I’ve got a Kona and did contribute a little a while back … but I’ve yet to get back using OVMS due to the power issues, although I have replace the 12v battery with a better one.</div><div><br class=""></div><div>It might be time for a re-write for the kona/ionic/niro support.</div><div><br class=""></div><div><br class=""></div><div><br class=""></div><div><blockquote type="cite" class=""><div class=""><div class="">

<div class="">I rang the Hyundai service centre, and apparently, my BMS
should not need any updates (build date 2021 vs 2020 cars with
the problem apparently), but I'm putting it in for a checkup
of the battery. Apparently, the BMS update was the subject of
a recall for those cars affected. I'm going to take it in
anyway in case. </div>
<div class=""><br class="">
</div>
<div class="">It seems, according to the OVMS, that the 12V is going from
13v down to 12v over about 3hours before (generally) being
recharged. Looking at that link you shared with me (and
related <a href="https://www.youtube.com/watch?v=lr3Z_z1C0Uk&t=965s" moz-do-not-send="true" class="">https://www.youtube.com/watch?v=lr3Z_z1C0Uk&t=965s</a>),
it should be more like 24 hours. It still should be
triggering a charge cycle - and obviously in this case it
seems to miss one and then it just goes downhill from there -
so maybe the BMS still has a bug; not helped by being forced
to trigger about 4x more frequently than normal!</div>
<div class=""><br class="">
</div>
<div class="">Assuming nothing is wrong with the car (which unless I
install some kind of external battery monitor like that
youtube clip), I can only assume that the 3hr drain is because
my Ioniq 5 module is polling too much (which, seeing I copied
the vehicle_kianiroev/src/ as my base, would mean THAT polls
too much as well). I still have the PollSetPidList() called
with the same data (albeit a copy) as the Kia. </div>
<div class=""><br class="">
</div>
<div class="">So in drafting this email I think I've hit on the problem,
which is when the car is off, but a V2 or V3 client is
connected (like the android app in 'background' mode), then it
uses the 'Charging' pollstate element. </div>
<div class=""><br class="">
</div>
<div class="">It has {OFF, Charging, ON} at the moment, which means
there's space for a 4th which I will assign to 'off,
not-charging and clients connected'. I'll see what I can do
to drop that right down in polling frequency and the number of
modules being addressed.</div>
<div class=""><br class="">
</div>
<div class="">At some point soon it might be worth me pushing up to a
fork in case anybody else wants to jump in! For example, the
Lock module that the kia has is not present in the Australian
version, but I suspect US ones with key-card ability might
have it.</div>

while the OVMS draws some power, unless you actually keep
the car alive <br class="">
by polling, that's normally no issue. The 12V battery will
be recharged <br class="">
automatically from the main battery by the car.<br class="">
<br class="">
The Ioniq 5 though has a history of issues with the 12V
battery. <br class="">
According to Andrew Till, a BMS update has fixed his issues:<br class="">
