    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>

                    <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="">

                      <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

                      </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

                      <div class=""><br class="">
                      </div>
                      <div class="">There is a small amount of RTC ram

                                            So, I seem to be going

                                            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
