modules). The server itself will also have a specific hostname and port it uses for OVMS
protocol v2 communications.
Hologram Activation
OVMS has partnered with Hologram and is providing a Hologram SIM pre-installed in every
OVMS modem board. In addition, Hologram have provided our community a coupon code valid
for US$5 off data usage:
Hologram Coupon Code: OVMS
When activating your Hologram SIM, you’ll need to enter the ICCID written on the SIM itself.
You can also get that electronically (without having to open up the package) from the web or
terminal shells with the following command:
OVMS# metric list m.net.mdm.iccid
The ICCID is also displayed during the setup process and on the modem configuration page
when using the web user interface.
OVMS Module Installation
Powering the module
If you intend to configure the module on your desk before connecting it to the vehicle, make
sure your USB port delivers sufficient power. We recommend using a USB hub with a separate
power supply or a direct port of your laptop / PC.
Server account
If you want to use the OVMS App and/or server based telemetry services, you’ll need a server
account. If you have not registered for an OVMS server account yet, you can do so before
starting the wizard to avoid needing to switch networks in between. There are currently two
public OVMS servers:
● Asia-Pacific: https://www.openvehicles.com/
● Europe: https://dexters-web.de/
You will need to create a user account first. Within your user account you then need to create a
vehicle account. You’ll need to pick a unique vehicle ID for this, e.g. your vehicle license plate
number.
