What is Teleport?

Teleport is a device that you can connect to your energy assets. It connects to the Teleport cloud, allowing you to securely read them out and control them through the Teleport API.

Supported assets

We support energy assets that can be controlled over RS232, RS485, and Ethernet, through protocols like Modbus, OPC XML-DA, SunSpec, and EN61850 (Real-time interface). Think of PV inverters and loggers (e.g. Huawei, Sungrow, ABB), Power analyzers (e.g. Janitza), battery inverters (e.g. Victron), wind turbines (e.g. Enercon), charging stations, and heat pumps. If we don’t have an integration with your specific asset yet, we can likely build the integration free of charge. See Connect to your asset for an overview of currently supported assets.


Once you receive the Teleport you connect it to your asset, typically by using a serial or ethernet cable. Some assets then require configuration, for example configuring the IP address and subnet mask for Modbus TCP. The Teleport often uses the cellular network to connect to the Teleport cloud, but it also supports Wi-Fi or ethernet. We make sure that the Teleport device is configured properly for your use case and that its firmware is kept up to date. For more details, see the Installation guide.

Read out

The Teleport will read out data from your asset and send that to our cloud. We forward them to a destination in your own cloud. For example, we push them to your database (eg. MySQL, Postgres, or Influx), message broker (eg. Kafka), or HTTPS endpoint. See the Data forwarding guide for more information. After successful delivery, our cloud will forget the messages within 2 weeks.


You can use the Teleport Cloud API to control your assets, or you can use the local Modbus TCP interface to interact with a Teleport device. Distribution System Operators can use the Real-time interface as customer endpoint for dynamic grid limits.

Control strategies

Teleport unlocks additional alternative solutions where it acts as a gateway for different types of energy assets such as batteries and the corresponding battery management systems (BMS), power analyzers and meters, and solar and battery inverters. Such solutions include but are not limited to Grid power control and Frequency containment reserve (FCR) where aggregation of data from a group of assets is required from third-party aggregators or an interaction between these assets is needed to provide local control. More details about the control strategies can be found on the overview of control strategies.


The ordering process for one or more Teleport devices consists of the following steps:

  1. Contact us at with the assets you would like to unlock flexibility for or if you want to discuss your project.

  2. We will send you an Asset Onboarding Form with questions about the asset.

  3. We will contact you to set up the one-time Data Forwarding integration with your database.

  4. We prepare and send you the configured Teleport to the designated address

  5. We agree to a date and timeslot that your installation partner will install the Teleport

  6. We will provide remote support to get your Teleport live.

  7. You are ready to unlock more flexibility.

Demo devices

We offer Teleport demo devices. Each demo device is configured for you and set up in the Withthegrid test lab. With a demo device you can start integrating the Teleport solution into your systems. You can test the API by sending control commands to simulated assets and setup data forwarding integrations. Our demo devices offer the following asset types.

  • Solar demo: simulates active power following the solar data graph. It is controllable, via limit production power schedules, and will reduce its active power based on the percentage given.
  • Battery demo: currently supports control of dispatch power. Its state of charge and available energy will change based on the dispatch power and therefore change over time. The active power always follows the dispatch power perfectly.
  • Wind demo: The wind demo simulates active power based on simulated wind speed data. The relationship between wind speed and active power is given by a power curve of a wind turbine. It is controllable, via limit production power schedules, and will reduce its active power based on the percentage given.
  • Power meter demo: simulates active power following the solar data graph. it is not controllable and therefore can only be used for data forwarding or in control strategies.
  • Heat storage: simulates a storage system with a furnace. It is controllable via setting asset parameters and turns on/off the furnace depending on the schedule it is given. The temperature will start rising once the furnace is turned on and will go down once it is shut down. The temperature limits of the furnaces can be configured.

Solar data

To simulate active power data, a solar curve is followed. The graph below shows an example of the active power in the demo with a nominal power of 1 MW. During daytime, it follows a sinusoid and during nighttime the data is random with a maximum of 0.1 % of the nominal active power.

Solar power demo

Wind power curve

To simulate the active power produced by a wind turbine, an approximate power curve for a wind turbine is followed. The graph below shows an example of the power curve in the demo with a nominal power of 1MW.

Wind power demo

Wind data

To simulate wind speed data, a sinusoidal pattern that repeats daily with some random variation is used. This can be seen in the graph below. The power produced by the turbine is then calculated using the wind power curve and the wind speed data.

Wind data

Please note: This data was obtained by generating a report every 15 minutes. If you generate a report more often than that, you will see more noise.

Monitoring SLA

We monitor the Teleports for you. We take care of:

  • Device management
  • Firmware management
  • Cybersecurity/patch management
  • Data forwarding management
  • API management

A standard and extended service level agreement is available. Contact us to know more.

Error Handling

In case something unexpected happens to the Teleport service we will inform you as soon as possible. Our error handling checks the following:

  • Asset availability
  • Connectivity
  • Cloud
  • Grid network outages (Netherlands only)
  • Asset anomalies

Assurances against lock-in

Typically we manage the Teleport device and Teleport cloud for you. We keep the device firmware up to date, monitor the stability of the cloud services, and develop new features. We do understand that you don’t want a vendor lock-in, which is why we can offer assurances like:

  • providing the source code of (and license for) the Teleport firmware
  • providing the source code of a cloud receiver that communicates with the Teleport device, to host in your own cloud environment
  • providing software escrow services which will enable you to receive a copy of the source code in case something unexpected occurs and guaranteeing long-term functioning of the Teleport devices and Teleport cloud for you


The Withthegrid Teleport takes the highest priority in addressing cybersecurity. We’re doing the following:

  • We’re ISO27001 certified meaning that our processes are in line with information security
  • Data is encrypted in transit through HTTPS
  • Our cloud services run on top of AWS infrastructure, in the EU only
  • Each Teleport device authenticates itself with a unique certificate
  • Teleport devices do not accept inbound connections
  • We’re following industry practices determined by ENCS (European Network for Cybersecurity)

If you’d like to understand these measures and impact feel free to reach out to us at to know more.
