Hi.
<div class="">I ordered my OVMS v3 module in march 2018, and
excited when I received it months later.</div>
<div class=""><br class="">
</div>
<div class="">The module has been connected in my Kia Soul EV from
around version 3.1.004, with OTA updates enabled, until July 12.
It was connected to <a href="http://dexters-web.de" class=""
moz-do-not-send="true">dexters-web.de</a> V2 server. It
usually reported data to the app, sometimes with long delays, at
other times not at all.</div>
<div class=""><br class="">
</div>
<div class="">From July 8th to July 10th, I drove the car 1450 km
from Copenhagen to Paris, then parked it.</div>
<div class=""><br class="">
</div>
<div class="">When I tried to unlock the car 5 days later, the 12
Volt battery was completely drained, and since then, the OVMS
has neither connected, nor sent beacons for the WIFI AP after a
factory reset. I have no idea what happened. To my knowledge the
module was functioning normally when I parked the car. On
dexters-web, I can see that the last update was received at <span

<br>
Too bad :-(<br>
<br>
I've had a look at the logs. Your last 12V reading was at 11.8V,
which normally would be still OK, but I suspect you didn't calibrate
the 12V measurement.<br>
<br>
See
<a class="moz-txt-link-freetext" href="https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/148">https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/148</a><br>
…and the new 12V section in the user guide.<br>
<br>
So the Soul doesn't top up the 12V battery from the main battery?
How much capacity does the 12V battery have on the Soul? <br>
<br>
Maybe we should add vehicle specific 12V capabilities & warnings
to the user guide. Or an overview table at the beginning?<br>

<br>
See above & issues, power management is not yet implemented, so
a reboot doesn't draw more power than normal live operation.<br>
<br>
The CRC error on the efuse BLK0 is very bad. BLK0 contains the
factory burnt MAC address assigned by Espressif. As efuses normally
can't be changed once burnt this signals a serious problem with your
ESP32.<br>
<br>
See <a class="moz-txt-link-freetext" href="https://github.com/espressif/esptool/wiki/espefuse">https://github.com/espressif/esptool/wiki/espefuse</a> -- you can
try the dump command and send the results to Espressif. If your
ESP32 really lost its efuses, I think that's a warranty issue.<br>
<br>
Mark, any idea on this?<br>
<br>
