We are working hard on OVMS v3. The development environment for the microcontroller we chose for v3 has finally stabilised to a point where we can rely on it. There will be a new revision of hardware silicon around the end of 2017Q1 and we'll most likely try to time the first production releases of OVMS v3 to use that as soon as it is available. But, the good news is that we have the production development environments available now, and the CAN driver (although early beta) is working well. All the components are finally in place and usable. This has caused us delays in our plans, but we are confident that our choice of microcontroller was the right one. This will give us a great platform for the future and most importantly allow us to keep costs down without being constrained by RAM/Flash memory storage (as was the case for the v2 PIC18 platform). Bluetooth and Wifi support are a bonus. Work on the firmware for OVMS v3 is ongoing, and we're hoping to release this to the open source team any day now. Some highlights of the coming features for OVMS v3 include:

  • Use of the industry standard MQTT protocol, for easier third party integration (in particular to IOT and home automation systems)
  • Event driven model for scripting events in the car (such as geofencing, homelink, charge settings, etc)
  • 3G
  • Wifi
  • Bluetooth
  • SD-CARD support
  • Reduced power consumption, and low-power sleep modes
  • Dramatically more RAM and FLASH memory, to overcome limits of PIC18 architecture used by OVMS v2
  • Firmware updates via SD-CARD and USB, without any special programming tools
  • Over-The-Air (OTA) firmware updates via wifi and/or 3G
  • Expansion slot and port for extra functionality

In the meantime, we continue to support OVMS v2. The hardware is still available on fasttech site, but we are over half way through what we think will be the very last batch.

In other news, we have partnered with hologram.io to provide a cellular network for OVMS users (both v2 and v3). Early feedback from our users has been fantastic, and this is now running in a bunch of OVMS cars. Use of this is entirely optional, and the cost-effectiveness will depend on where you are in the world and what other cellular options you have. We're not forcing you to use Hologram; just making it easy for you to choose them if you want. OVMS v3 will come with hologram.io SIMs included as standard (but easily replaced if you choose not to use it). For OVMS v2 users in USA, with the imminent shutdown of the AT&T 2G network, we recommend Hologram.IO now. You can get SIMs from Hologram directly at https://hologram.io/store/, and Tom has penned an excellent write-up of how to switch to Hologram at https://www.idleloop.com/tesla/ovms/hologram.php.

Buy v2 or wait v3?

Should I buy v2 or wait until v3?

OVMS v3

Hi Mark,
I'm very interested in v3 to use with Renault ZOE. Are there any developers working on it? Would be interesting to tranfer logdata of Roadtrips und state of charge of battery to integrate in home management System.
There is an Luxemboug developer who works on CanZE (http://canze.fisch.lu/)
When could one count with first versions?

Sorry, but we don't have

Sorry, but we don't have anybody currently working on the Renault Zoe vehicle.

We are an open source project, and vehicle support requires a develop to work on coding the vehicle support module.

Any news?

Hello. Any news about starting selling new version? Or maybe old version, it's still popular to use?

Any idea when v3 will be

Any idea when v3 will be available. I have a leaf and have been unable to obtain a v3 and am desperate to start coding. Would happily purchase a v2 if I could find one.

Any news on disponibility of v3 (or v2)?

Any news on disponibility of v3 (or v2)? Many months has passed without any update... many new volt owners are waiting to get one! :)

The first v3 firmware does

The first v3 firmware does not have support for the Volt Ampera / Chevy Volt vehicle type. So far, no developer has come forward to help porting the firmware to that vehicle. Technically, the hardware can support the vehicle - but we are an open source project and require someone with the vehicle to port the support over from v2 to v3.

We expect support for that vehicle type to come within the coming few months. As the v3 hardware is now released, this will be easier to get done.

Problem with OVMS Server V3

Hi!

I've a MQTT Server, I configure all the data on the OVMS section, but doesn't connect I get the next message:
[18:26:27]server.v3.connecting
[18:26:27]server.v3.disconnected

The configuration is OK, and the server is accesible througt internet (I try with MQTT.fx and works fine), but from OVMS allways get the disconnected message, someone knows what's happening?

(The disconnect message is with host and with the ip of the mqtt server...)
