Introduction

Welcome to the documentation pages of the WARP product line from Tinkerforge.

Here you will find the documentation for installation and configuration of:

This documentation is constantly maintained and expanded. If you have ideas for additional documentation or examples, please let us know. We also gladly add more compatible devices to the list or good questions/answers to the FAQ.

Philosophy​

We believe that products belong to customers. That's why we develop solutions with open interfaces and consistently pursue an open source concept (hardware and software). Our products are developed and manufactured in Germany (Made in Germany). We design our products for long service life, focus on quality and easy repairability.

Community​

The development of our products is done in close cooperation with our community:

Whether new ideas, bug reports or beta testers: We appreciate the intensive collaboration!

Open Interfaces​

WARP Energy Manager 2.0, WARP3 Charger Smart and WARP3 Charger Pro can be integrated into other systems using open interfaces:

No Cloud Required​

We try to implement as many functions as possible locally on the device. For example, the charging log is stored locally on the chargers. If a billing PDF should be generated from it, this is done on the charger and in your browser without a cloud.

In cases where we technically depend on data from a cloud (e.g.: PV Forecast, Dynamic Electricity Prices, Remote Access), we still try to implement as many functions on the respective device as possible and not in the cloud. This means we try to avoid storing data in the cloud whenever possible, but rather store it locally on the devices.

For example, Remote Access, which is also used by the Android and iOS apps, is technically a VPN tunnel between the browser/app and the device (WARP Charger or WARP Energy Manager). Data exchange is encrypted between the two participants. We have no access to your device or your data.

Compatibility with Third-Party Devices​

Our goal is that our products also work with devices from other manufacturers. This makes it possible to access data from PV inverters, electricity meters or battery storage systems from other manufacturers and use them for example for PV excess charging or dynamic load management.

Using Solar Power​

Photovoltaic Excess Charging​

WARP3 Charger Smart and Pro can perform PV excess charging directly and without additional hardware. This means that instead of feeding excess energy from the PV system into the power grid, it is charged into the electric vehicle. To do this, the charger only needs to be electrically connected and brought into the network via LAN or WLAN. Additionally, an electricity meter must be available at the house connection, which can be read by the charger. PV excess charging is then performed using the power measurement values from this electricity meter. An overview of currently supported devices that can measure power at the house connection can be found in the article compatible devices.

Operating Heating with Photovoltaic Excess​

Similar to PV excess charging, a WARP Energy Manager 2.0 can be used to set a heat pump with SG-Ready interface to extended operation mode. This way, the PV excess can also be used for heating.

Dynamic Electricity Prices​

WARP3 Charger Smart and Pro and the WARP Energy Manager 2.0 can directly retrieve electricity generation prices from the power exchange. Additional costs such as grid fees and taxes can be individually configured. This way we support any provider of dynamic electricity prices without depending on an individual implementation of the provider's interfaces.

§14a - Controllable Consumption Devices​

Chargers, heat pumps and battery storage systems are so-called controllable consumption devices according to §14A. We offer various options for meeting the legal requirements. See Tutorial - Controllable Consumption Devices

Charge Management​

Operating Multiple Chargers on One Line - Static Load Management​

If multiple WARP Chargers share a supply line, the charging currents of the connected chargers may need to be limited. WARP3 Charger Smart and WARP3 Charger Pro have integrated charge management. The chargers only need to be within a network (LAN, WLAN). A separate electricity meter is not necessary for static load management.

Insufficiently Dimensioned Grid Connection - Dynamic Load Management​

If the grid connection is not sufficiently dimensioned to operate one or more chargers, dynamic load management helps. Especially with larger properties, the grid connection is often mathematically maxed out if it is assumed that all consumers are switched on. In practice, however, this almost never happens, so chargers can still be operated. The chargers must then be controlled depending on the current phase currents at the grid connection to ensure that none of the three phases is overloaded. If a suitable electricity meter is available at the grid connection that can measure the phase currents, dynamic load management can be handled directly by a WARP Charger. An overview of currently supported devices that can measure power at the house connection can be found in the article compatible devices.
