Pioneering a new way

myenergi is an award-winning British designer and manufacturer of renewable energy products that increase the self-consumption of green energy. Its zappi product was one of the world’s first solar and wind compatible electric car chargers. The company’s vision to optimise renewable energy use at home, is underpinned by industry-leading technology that enables customers to take control of and manage their eco-smart products in a user-friendly way. 

‍

myenergi appointed ddroidd in 2020 as a development partner to undertake various application development projects within its customer-facing platform, data dashboards and analytics engine. 

‍

Technical partner of choice

As myenergi’s long-term technical partner, ddroidd delivers consultation, application management and software development, as well as automated and manual testing, for the company’s myaccount portal, mobile app, admin console and data server.

Handling energy tariffs 

With a wide range of UK energy tariffs available to home consumers, myenergi collects tariff details from energy providers and displays them in the myaccount portal using features developed and maintained by ddroidd:

1. APIs - For the energy providers that allow this, there is a daily job that imports the data into the database to display the users’ available tariffs for the next 24 hours.
   
2. User input - Customers have a dedicated section in the myaccount feature where they can input multiple tariff periods, as per their contract, to determine their usage and display their budget. 

‍

Tariff scheduler 

We developed a smart scheduling feature to help users optimise energy consumption that suggests the best times to charge electric cars and heat water based on variable energy tariffs. Users can also create custom schedules for their myenergi devices: 

1. Budget boosts - “charge my car/heat my water tank when the price is below x pence/hour”
2. Scheduled charge - “charge my car/heat my water tank every x days from 1 to 2 o’clock” 
3. Single charge - “charge my car/heat my water tank one time on TUE at 2PM” 

‍

Energy usage graphics

An essential feature within the app and myaccount allows users to monitor and visualise their energy usage:

1. How much energy they’ve imported from the grid 
2. How much energy they exported to the grid 
3. How much energy they’ve consumed from their renewable sources 

‍

Users can view these insights for different periods (daily, weekly, etc.) and filter the data per device.

“As ddroidd’s first customer, we have loved seeing the company grow. Over this time, we have built a strong partnership and very much see ddroidd as part of the myenergi family. We really appreciate the continuity of people who take the time to understand our business and work as a blended team. ddroidd’s experts not only know their tech, but they are extremely professional and reliable. I look forward to continuing our long-standing collaboration.”
