GivEnergy Integration

  • Works with all GivEnergy Inverters including AIO, Hybrid, Gateway’s and Plant EMS
  • Works with multiple battery strings from a single inverter.
  • Works with single Inverter systems. 
  • Only Two pieces of information required to add your inverter to the service, plus a name of your choice.
  • Dual All-In-One integration via GivEnergy Gateway
  • EMS integration in Beta testing

Solar Panel Setup

  • Works with single and multiple array systems.
  • Only three pieces of information required, all of which should be available from your install.
  • Integration with Solcast allows you to use your Solcast hobbyist account for fetching the forecast (rather than the default system)

Consumption / Demand Estimation

  • Your demand estimation is based on your own historic use of your inverter.
  • The estimate is based on a rolling average,  and then adjusted for the the day of the week. User settings, allow for a contingency to in the demand calculations. E.g. an additional 10%.
  • High consuming / intermittent loads such as EV charging can be excluded from the estimated demand calculations.

Generation Forecast

  • Fully integrated weather / solar forecast. No separate third-party account required.
  • Solcast can be used as an alternative. 
  • Choose to use the service to automatically adjust the target charge, based on estimated demand and forecast generation. User settings, allow for a contingency to in the demand calculations. E.g. a reduction of 10%.

User Settings

  • Version 2 provides time block control. Multiple time blocks can be added to the 24 hour schedule, each with their own control plans. 
  • Separate settings provided for charge and discharge control, allowing the user to set as per their requirements.
  • Settings include, time charge, tariff charge, and trigger charge based on the battery state of charge. 
  • Similar for discharge, where you can choose to stop, limit or export battery charge. 
  • Adjustments allow for limiting the charge power, discharging to a reserve level and similar depending on your inverter model. 

Battery Charge Control

  • Octopus Integration provides Tariff based charging control.
  • Non-Agile users can choose to charge when the import price of grid electricity is below a threshold.
  • Non Octopus smart tariff customers can set up charge and discharge plans based on the time of day. 
  • Agile users charge during the cheapest agile slots.
  • Agile users can set additional charge slots, to reduce the risk of missing the target charge %.
  • Set the charge and discharge plans for the time of day you want them to operate. 
  • Stop Discharge or Force Discharge based on electricity pricing.

Dashboard

  • A detailed dashboard is included, which is responsive to your device (desktop / mobile)
  • The detailed dashboard provides:
    • Summary of Consumption, Generation and Battery use today.
    • Carbon Widget displays current carbon intensity for your region.
    • Simple Weather Forecast
    • 7-day summary chart of generation and consumption
    • 7-day summary chart of battery charge and discharge
    • Forecast Generation, Consumption and Battery Energy Required for Tomorrow
    • Summary of current charging and discharging slots based on your settings.
    • Option to override target charge e.g. select 100% rather than optimised target charge.
  • A visual schedule updated at 9pm each day provides a summary of the charging plan.
  • An activity summary can be emailed out up to 3 times a day to warn you of errors. 

Charts

  • Annual, Monthly and Weekly Charts for:
    • Consumption
    • Generation
    • Battery Charge / Discharge
    • Self-Consumption
    • Grid Import / Export
    • Energy Flow

Future Development

  • Will continue to consider ease of use as far as possible!
  • Will be partly driven by the community.

Potential Changes to GivEnergy Cloud Service Access

What has GivEnergy announced?

On 31 March 2026, GivEnergy emailed a survey to users asking how much they would be willing to pay for access to its cloud services.

On 1 April 2026, GivEnergy clarified that the specific services that may be placed behind a paywall have not yet been finalised. However, the announcement suggests that cloud services and use of the API are likely to be included.

How does this affect third‑party services like MyEO?

MyEO and other cloud services (such as Octopus and Axle) use the GivEnergy API to access data from your system.

GivEnergy currently offers:

  • A commercial (paid) API
  • A home user API, which is currently free

MyEO uses the home user API, which is currently free for both you and me.

Will I need to pay for a GivEnergy subscription to keep using MyEO?

At this stage, it is not yet confirmed which services will require payment. Because of this, I can’t yet confirm whether a paid GivEnergy subscription will be required to continue using MyEO.

What happens next?

This information will be updated once GivEnergy provides clearer details on:

  • Which cloud services will be paid
  • Whether access to the home user API will be affected

Planned Maintenance

From 11am Saturday 16th Nov

Following the outage earlier this week, I’ve decided to move the website/service to a new hosting provider. While the outage prompted the timing, it wasn’t the only reason.

The key benefit of the move is increased computing resources, which are essential given that the site processes hundreds of commands every 30 minutes. 

Migration Timing and Impact

The migration will start at 11 am Saturday, 16th November. Unfortunately, migration can take 24–48 hours, but it is often much quicker.

During this time:

  • Maintenance Mode: The site will be in maintenance mode (inaccessible) to freeze the database and pause account changes.
  • Automation: Scheduled automation should continue, but there may be a brief gap when the internet transitions to the new server.
  • Temporary Issues: Some features, such as charts and parts of the dashboard, may not work immediately after migration. These will be fixed as quickly as possible.

If you’d like me to temporarily pause your settings at 11 am to allow manual control, please let me know. I will also be able to access the settings during the majority of the migration for last minute changes.
