Plishka: Home energy management app
A mobile app for homes with solar panels, a home battery and an electric car. It showed, live, where the home's electricity came from and where it went, and sent each home its own alerts. We built it for Naatu together with the Virtual Power Plant web app, and it launched on the App Store and Google Play in April 2022.

01 · Business context
The problem
Naatu wanted one app that showed a household everything about its electricity: solar panels, home battery, electric car charging and the appliances in use.
That meant processing a lot of complex data and turning it into clear, interactive charts. The app had to stay easy to read for people with no experience of energy data. It also had to warn them about problems in time and help them cut their bills.
The client
Naatu
An energy company from Gdańsk, Poland, focused on saving and storing energy. Today it offers a home battery and EV chargers, and connects homes with solar panels, heat pumps and batteries to a virtual power plant.
Plishka was the household half of a two-app project. The other half, Virtual Power Plant, was a web app for detailed analysis. Both ran on one backend that we built.
02 · Key features
What we built
A React Native app for iOS and Android with MobX, on Node.js and Strapi, sharing its backend with the Virtual Power Plant web app. These were its most important features.
-
The home at a glance
The main screen showed energy flowing between the solar panels, the grid, the battery, the house and the car, with animated arrows.
-
Battery and island mode
Users saw the battery's charge, the time to a full charge and the share of energy from the panels and the grid. When the home was cut off from an unstable grid and ran on its battery, the app said why and logged each outage.
-
Reports and appliances
Use, solar production and costs by day, week or month, a breakdown by appliance, and peak and off-peak hours.
-
Personal alerts
A scheduler on the server analysed each home's data and sent push notifications: appliance failures, coming storms, battery events and offers based on the home's energy use.
