    Open Vehicle Monitor System (OVMS) - Technical Discussion

    The commands you list are old v2 format. For v3 it is just ‘stat’ without the ‘?’. You can send a single ‘?’ to get a list of commands.

    anyone know when will Netflix and Youtube be avaliable for HK teslas

    It does appear that hell is indeed freezing over. Some amendments are working their way through the legislative process here now that will remove limitations on the visual display while the car is parked, allow summon (engine running while driver not in seat), as well as a few other such...

    Communications Problem Service Required VDS Message

    None. Logs don’t say much, and VMS was rebooted. Wouldn’t have been able to get in remotely anyway with obd process killed.

    Communications Problem Service Required VDS Message

    FYI (for others in the same boat): From the logs, the issue started a week or so before vds comms fault was shown. Linux out-of-memory called, and killed obd, inetd, and watchdog (so no remote diagnostics, or magic restart). Then a week later another out-of-memory killed vms processes (hence...

    Communications Problem Service Required VDS Message

    Easiest is ‘re start’, wait a few seconds, then ‘re list’. That will show a summary for each ID seen. The ‘re stop’ command stops collecting that data. You can also get a full dump (can log …), but harder to do remotely.

    Got your email and replied. Looks like VMS is locked up / non responsive.

    Sometimes it slips down the side. Can either try pulling up on those cables, or remove the side panel (just clips on).

    Old Roadster pack is recovering after going below CAC 76?

    Are you sure about that CAC 39.03 and ideal standard range 170 miles? Those two numbers should match, but are way off for you.

    Diagnostic Port Index

    FYI: I’ve been told by my supplier that the Tesla Roadster (and pre Sep 2015 Model S) diagnostic connectors and pins are now ‘end of life’ and no longer being manufactured. They are selling their remaining stock but won’t be able to replenish after that.

    Caution - Annual Service - Car power-down - GPS issue

    I’m sorry to report that Steve passed away in his sleep on July 4th. He was such a valued member of this, and other, communities and will be sorely missed. I think the cable was passed on to others to handle before he left us, but not sure who has taken on this.

    How and where to pull plug / power to the VMS?

    If the VDS is giving VMS comms error messages, but OVMS is still able to communicate with the VMS, that implies the issue is more like with your VDS, or the cabling. Note that all three (VMS, VDS, OVMS) are on the same instrumentation CAN bus.

    Help: VIN 729 Roadster not starting, VMD-VDS communication fault

    Issue was corrupted firmware in the VMS resulting in it being unable to boot. Fix is not trivial and involves using CAN bus tools to re-upload firmware files to the VMS. In USA, either Medlock or Gruber should be able to help if you have the same issue. If you have OVMS with an OVT1 cable and...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    There are low level developer commands. Better to use the standard power control commands. You can use ‘power ?’ to see the options.

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    The command I gave is for the latest (current) 3.3 firmware. If you are running older firmware, it is probably ‘simcom’.

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    As a few have asked about this, I have finished a video we have been working on: You can follow the general idea of that video, but use 'power cellular off' and 'power cellular on' as the script commands.

    TPMS disable / delete on Model S 2012 to late 2014 "Baolong"

    You will find this post from the OVMS Developers Mailing List, July 2020, interesting: TPMS subsystem, Roadster, Model S, Baolong, and some UDS hacking/cracking Back then, I too was told that the early Model S and 2.x Roadster TPMS systems were 'the same'. They aren't. The only thing in common...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    The default settings should already do that (only update every 10 minutes or so), and the updates are tiny. Those 1MB and 2MB sessions lasting a few hours make no sense. Please email (or PM) me the output of 'module summary' (go to the shell, and type in that command).

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    Suggestions: Only use server v2 protocol (not v3 mqtt). Make sure TLS is OFF for server v2. In general, leave the settings at defaults. Don't leave an App/Client connected all the time (usually only an issue for automation systems). I have seen cases where people living in very marginal...

    TPMS CONTINUES TO FAIL... [RANT] And they are gonna send people the mars?

    Sounds like the argument over floor numbering where I live. Here the 1st floor is the ground floor, and the 2nd floor is one floor up. Also floors 4,14,24, etc, are typically 'missing' (as an unlucky number that nobody wants to live/work on). The question, of course, is whether B1 is the first...

    3.0 Battery Longevity

    Glad to hear it worked out, and thanks for the feedback. Difference of 2% is good.

    Old Roadster pack is recovering after going below CAC 76?

    OVMS just shows the same as on the 1050 diagnostics screens. It should be accurate, but typically only significantly updated after a charge.
  28. markwj

    Any reason not to leave roadster plugged into 120v outlet?

    OVMS merely starts the charge. The choice as to whether to cool or not is entirely up to the car.

    3.0 Battery Longevity

    Unfortunately, I parted ways with my roadster a while ago. I am aware of the mentioned balancing limit of minimum 8x%, but assume it is based on SOC Max (ie; highest brick), not the driveable SOC (SOC Min).

    3.0 Battery Longevity

    First I’ve heard of that. You saying the 3.0 packs can’t balance in standard mode? That doesn’t really make sense. Balancing in range mode is not desirable as it would mean leaving the car at a very high state of charge for several days / weeks, which is well known as bad for the battery. I...

    Don't bring your car to oversea from the US, my car is dead

    Simple answer is that it is not an international warranty. Details can be found here: https://www.tesla.com/sites/default/files/pdfs/quick-guide-for-ownership-experience-grey-market-grey-vehicles_NA.pdf

    3.0 Battery Longevity

    In general, to balance the car; charge it in standard mode until it completes the charge and then don't touch it. Leave it connected to the EVSE and monitor the 1050 diagnostics balancing screen (1s and 0s) to see the balance progress. Expect around 1% per 24 hours (or less) - it is a slow...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    Not that I know of. In general, OVMS has the capability to do what can be done from the VDS. I don't think the VDS can open the trunk.

    Do I risk bending my trunk panel if the right side won't latch?

    Answer: Probably not a good idea. I concur with the tape-it suggestions.

    Help with TPMS Sensor programing on 2010 Roadster

    If you change one or more sensor IDs, you need to re-program all four IDs into the TPMS ECU again (and in the correct wheel order). Short story is that the ECU is programmed (over the K-line bus on the OBDII port) with the four unique IDs for each of the four wheels. The ECU then goes on to...

    Sorry for the late reply; with COVID-19 raging here, I haven't been able to be around TMC much lately. The "Denied Registration" message means the cellular network denied registration to the SIM card. This normally happens when the SIM tries to connect to the network before the SIM has been...

    For those upgrading to the 4G modem, you *must* be running 3.3.001 firmware. Simplest way to get that is to set your release level to 'edge' and do a normal OTA update over wifi. You can also get it from this URL: http://api.openvehicles.com/firmware/ota/v3.3/main/ovms3.bin For the hardware...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    That would be helpful. You should be able to re-use the old SIM card, and just swap the modem. Take care with orientation (white triangle on modem board and main board should align), and be careful not to bend the pins. You will also need to get the v3.3 firmware on your OVMS module (as the old...

    Open Vehicle Monitor System (OVMS) - Technical Discussion

    Hologram currently uses T-mobile and AT&T Networks in USA, and the modem in your OVMS is a 3G modem. The SIM card shouldn't be an issue. As 3G is turned off on the networks, you may experience more connectivity problems, depending on reachability of 3G networks. You can upgrade just the modem...

    Just to make sure you understand the options (keeping the explanation as simple as I can, sacrificing some technical accuracy) I copy-and-paste here: The roadster battery pack (aka ESS) consists of 6,831 individual cells (each around 4volts when fully charged). The cells look something like fat...

    Need my roadster geniuses / Please Help Logs/ 1.5 not charging or battery issue?

    Given enough time, 100%. It is really a crapshoot. I have heard of cars that are 2+ years past the 'snip' of a brick cell, and still on the road driving fine. Others have had the same failure in a different brick a couple of months later. The surgery itself is very simple. The problem is that...

    Need my roadster geniuses / Please Help Logs/ 1.5 not charging or battery issue?

    The ESS SOC screen shows SOC MIN 48% MAX 97%; that is indicative of a massive imbalance. The balancing screen shows 98 1's and only one zero; that indicates the car is trying to drain the voltage of 98 bricks down to the level of one single lowest brick. The flash/ahr.log file shows the...

    Need my roadster geniuses / Please Help Logs/ 1.5 not charging or battery issue?

    ^this. Brick #67 (0...99) or #68 (1...99), depending on how you count, is bad. Your car can only charge until the brick with the highest voltage (SOC MAX) reaches the upper limit, and can only discharge until the brick with the lowest voltage (SOC MIN) reaches the lower limit. The range...

    I don't think it is busybox - those are just userspace tools. I suspect the bootloader; either that or it is a huge coincidence that those are the files used to boot Linux from. Everything else on disk looks fine. That is what I have been working on for a while. Hard with zero technical...

    Having worked on this, I feel the need to warn users about powering off the VMS without proper shutdown.
