Ok... So the module updated to EAP last night, as expected. The
display (screen shot) shows zeros for Ambient, Charger/PEM, Motor,
and battery; 12v is live, as is the odometer. TPMS is missing. Is
there a reason that the bulk of the metrics aren't read? Are they
not present on the CAN bus, or is the module explicitly not watching
for them until the car wakes up?<br>
<br>
If I wake the car up, Ambient, Charger/PEM, motor, and battery are
immediately updated, but TPMS is still missing. <br>
<br>
For consistency and less confusion, I would like for the TPMS to be
populated in both screen shots, and showing zeros until the car is
driven. And by "consistency" I do NOT mean "remove the other
metrics too". I'm trying to be careful what I wish for...<br>
<br>
When I put it in Drive for a few minutes, the TPMS icons do appear
with live data. I'll let the car sit for a few days, and see what
happens to the display. What I expect is that they will remain
present, even if not live.<br>

Ok, EAP is set. Let's see what happens at 2am...<br>

I think best to move to EAP and see if that improves the
situation. On ‘edge’, you will be getting an update (and
reboot) once every night or two.

<div text="#000000" bgcolor="#FFFFFF" class=""> Hi
Mark,<br class="">
<br class="">
Yes, I understand that. Not expecting such a
dramatic change as saving data in NV RAM. The end
user presumably won't have their module rebooting
very often, so this isn't worth trying to save stuff
across reboots.<br class="">
<br class="">
I'm trying think back to when the behavior started
to change. It might have been when I moved off the
Main branch to Edge because of the bug with OBD2ECU
CAN initialization, so module reboots are far more
frequent. I'm tempted to get back on Main, or at
least EAP, but I'm also vaguely remembering that
there was a change related specifically to "stale"
data that put a lot of data out of reach for a day.
This latest UI behavior change was the straw that
caused me to write.<br class="">
<br class="">
It seems like populating data takes a lot longer now
than, say, 6 months ago. Did something change a
while back that has led to this? Part of the
puzzle, perhaps, is that we have two moving pieces,
the Module and the App. I'm on Android, if that
matters.<br class="">

Greg,
<div class=""><br class="">
</div>
<div class="">I think the issue you have is that
after a firmware update the module will reboot.
That will mean it will lose the metrics for
TPMS.</div>
<div class=""><br class="">
</div>
<div class="">Those metrics won’t come back until
the car has been driven.</div>
<div class=""><br class="">
</div>
<div class="">I don’t see a simple solution. We
could address it in v2 protocol by not sending
the tpms message unless the metrics are defined,
but that might still mess up the stale
indicator. That wouldn’t affect the individual
metrics and v3 protocol we are trying to move to
for the future.</div>
<div class=""><br class="">
</div>
<div class="">There is a small amount of RTC ram
that is retained through a reboot. Perhaps we
could have a mechanism to save+restore certain
metrics there? But not at all simple.</div>

I am on Edge, and it updated 2am local

p.s. Just saw your EAP announcement.
With the 3.2.012 code coming, it will be

the reset. I'll let you know!<br class="">

Greg,
<div class=""><br class="">
</div>
<div class="">What firmware version
are you running in the module? If
EAP/MAIN 3.2.011, can you try
updating to the edge release? I
suspect you are seeing the bug with
3.2.011 and the TPMS protocol v2
message.</div>

Hi folks,<br class="">
<br class="">
So, I seem to be going
backwards with OVMS and my
Tesla Roadster...<br class="">
<br class="">
I'm looking at the OVMS app
on my Android phone. <br class="">
<br class="">
Used to be that I'd see the
TPMS data - pressure and
temperature - as it was the
last time the car was
driven. <br class="">
<br class="">
Then it turned into zeros.<br class="">
<br class="">
Today I see it's gone
altogether. This is not
progress.<br class="">
<br class="">
What I want to see is the
data from the car, as last
it was read. I do not care
that it is not live. In
fact, if it were live, that
would mean that the car is
in Drive, which (hopefully)
means that I am in my car.
If so, I have <b class="">no
use</b> for the OVMS, as
the data is sitting right
there on the car's display.<br class="">
<br class="">
Is there any way to get the
old functionality back?<br class="">
<br class="">
Greg<br class="">
