OVMS server

OVMS = Open Vehicles Monitoring System

This server is meant as an independant EU based alternative to the standard server api.openvehicles.com. The server is open for any OVMS user (not just Twizy drivers).


This service is offered strictly on a private base, free to use and without any warranty.

Any aspect of this service may be altered or discontinued without notice.

There is specifically no data security guarantee. The OVMS transmits data via V2 protocol with weak encryption ("paranoid mode" = RC4 encryption).

By using this service you agree that your stored data may be used by me for anonymous bug/crash analysis and usage statistics. Your data will never be forwarded by me to any third pary without your explicit consent.


I (Michael Balzer) have joined the OVMS developer team in 2012, my priority besides the framework is currently (since 2021) the VW e-Up / Seat Mii / Skoda Citigo support. I implemented the Twizy support before (2012-2020).

I am a graduated computer scientist and owner of the web company expeedo. This web service is based on my web framework ShopDriver.

Server / Location

I rent this server via my company from Velia.net. velia.net Internetdienste GmbH is a part of the GoDaddy, group.

The server is located in Frankfurt (Germany), near DE-CIX in the data center Telehouse Rechenzentrum. The server is powered CO2 neutrally on 100% renewable energy.

Note: to be able to use the special GCM ID (for notifications) you need to use the Android App version 3.11.1 or later.

iOS notifications do now also work from this server. You need to use the iOS App version 1.8.2 or later.

You can also configure notifications by email.

Att: push notifications currently need an active V2 connection, a pure MQTT setup is not yet sufficient.



Is this service valuable for you?

Please consider a regular donation to show your appreciation and to support me.

The high availability and dependability of this service is the result of my continuous work. I take care of server maintenance, fixing issues, do support and work on general OVMS development benefitting all users — all voluntary and unpaid.

The rising user and access numbers have an impact on the server requirements and the time I need to spend. Sadly, donation amounts have meanwhile been stagnating at a low level.

Every contribution counts!

1€ per month and user is sufficient to back the server costs.

You can easily enable a monthly donation via the Paypal button (this is going to dexter@dexters-web.de), and stop it any time from your Paypal account. Alternatively send by bank transfer or standing order with subject "Donation OVMS" and your email/login to DE21 4545 0050 0001 8301 16.

Thank you!
Michael Balzer
