Vibecoding against blackouts. 10+ new and useful applications and widgets that Ukrainian IT professionals created in case of power outages

Threads user Mykola Padiy presented a new web service that collects outage schedules for all regional energy companies in Ukraine and displays them on a single interactive map. The project is completely free for users and exists thanks to community donations.

Each light on the map corresponds to a house in its queue. When the light is on, the light glows yellow, and when the queue is off according to the schedule, it goes out. The data is updated every minute.

The site has a special time slider that can be moved forward to view the outage schedule for the evening or the next day. The service automatically collects information from the official websites of YASNO, regional energy operators (via ua-outages) and verified community mirrors. A Telegram bot has been developed for user convenience.

Owners of Deye, Victron, EcoFlow or Growatt equipment can connect their inverters directly to the site. In this case, the bot will notify not only about the planned schedules, but also about the actual disappearance or appearance of voltage in the network.

Aitivka resident Viktor Sapayev shared his own development in Threads — a useful widget for Apple Watch that displays a graph of light availability on the watch screen.

"Given the light situation, this could be one of the most useful applications for Apple Watch. Outage schedules, actual light availability, and air alarms — all right on the watch face. With support for multiple addresses. Public release coming very soon," the IT expert announced, urging people to join the testing.

Later, the developer announced that the main priority of SvitloWatch is still the Apple Watch, but in parallel he adapted his development for the iPhone. "Some people wanted to see information about light and alarms directly in widgets on the phone. So some of the functionality has already migrated to the iPhone," the IT expert explained.

Meanwhile, another Ukrainian developer has created SvitloChecker, a compact Windows program that displays a schedule of power outages above the taskbar. The application shows when the lights are about to go out or come back on, and warns you of an impending outage.

According to the author, SvitloChecker displays the current state of the electricity supply and a schedule for six hours ahead. If you click on the widget, you can view the schedule for the entire day, including the next day. When you hover over it, the program shows the exact time of the nearest shutdown or restart and a countdown.

The application also has a notification system: 30 minutes before the shutdown, the capsule appears and flashes. It also reacts to changes in the regional energy company’s schedule. The user can configure sound signals, select a region and a queue. The developer has also provided a mode in which the program will not interfere with work: SvitloChecker automatically hides when starting games and full-screen video. There is also an auto-hide function. More about the development, which is still relevant for residents of the Mykolaiv region, in a separate article

Aitivka resident Mykyta Lapin, in turn, developed an iOS app that shows the approximate battery life of Marstek stations under current load. According to him, this feature is missing from the manufacturer’s app, so he decided to make his own.

"It shows this time on the widget, and in Kyiv, according to the YASNO schedule, it tells you whether there will be enough charge before the light returns. For those who find this convenient, please visit the App Store page," the developer urged in Threads.

He clarified that the application works only in the same network to which the charging station is connected. Later, taking into account user feedback, Mykyta Lapin added synchronization with outage schedules for 19 regions to the application, and also expanded the line of Marstek models with which his application works.

Systems Designer, registered on the social network Threads as Alex Brazh, has developed an alternative application for Fossibot stations.

"I use the Fossibot charging station, but it has a disgusting application, so I made myself a beautiful one and published it for everyone on Google Play and AppStore. It should work with all Fossibot models, and even stations from other brands that also work with the BrightEMS application. It works via Bluetooth," the specialist said .

As the author of the application says, all basic features are available for free, and the paid Pro version exists only to "say thank you to him."

In turn, Threads user Ivan Kravchenko, registered under the nickname fingro, uploaded a widget to the Deye station.

"My station now has a widget on my iPhone that looks better than the native interface. Battery charge, real-time consumption, how much more time it will last before discharge, the weather in Kyiv, and even a neon strip, like at the station itself. I built everything in one evening. Now I look at the lights in my house as if it were a stock chart," the author of the widget noted .

To create the widget, he used Scriptable + Deye Cloud API, a free JavaScript application. "The script receives data from the Deye cloud service and displays the widget: battery charge, consumption, discharge, tabs," the author commented.

Ilya Yankov, creative director of marketing solutions agency Havas Engage, has created a tool that turns a user’s outage schedule into a melody. "The idea is to give yourself and others a chance to get a little distracted and experiment with sound," Yankov explained the development, which he worked on with Claude.

Ilya connected DTEK data so that the melody would be based on the outage schedule at the user’s address. It took about ten minutes to create the basis of the service. The name "Blackout FM" was also suggested by AI.

The service is in experimental mode, some functions are still being refined. More about this extraordinary development can be found here.

Ukrainian iOS developer Oleksiy Borunov from the independent Melissun’s Team has launched the Blackout Math application — a utility for calculating the autonomous operation of an apartment or house during power outages. In fact, the application answers a practical question: will a specific station be enough for a several-hour blackout? The idea for the project appeared against the background of regular blackouts, when the developer first encountered the problem of choosing batteries and portable power stations for the home.

According to the author, during the first power outages, he had to independently deal with dozens of technical parameters: C-rate, DoD, real battery capacity, inverter efficiency, as well as read profile chats, forums, and watch video reviews.

Blackout Math was originally created as an internal calculator "for myself", but later grew into a full-fledged application with a UI aimed at a wide audience .

Ukrainian developer Yuriy Valigursky created Generator Tracker — an application for recording generator operation, fuel consumption, and maintenance. The tool can be useful for condominiums that received generators under the state program "SvitloDIM" and now have to monitor their operation and costs. The application is free for iPhone, works without the Internet, and does not require registration. For Android, the developer is preparing a free Lite version, which is still in the testing stage.

The application allows you to keep track of the operation of one or more generators on your smartphone. Instead of writing in a notebook or spreadsheet, the user can record the start and stop of equipment, fuel consumption, and maintenance. This can help those responsible for the equipment to systematize data on its use, and the heads of condominium associations to prepare a clear report for the co-owners of the building. About this application — in a separate material dev.ua.

Another Ukrainian developer has created Power App, a native application that allows you to monitor the status of EcoFlow, Bluetti, and other charging stations directly from your Mac without being tied to the cloud or an internet connection. Most Mac users work from battery stations, but official mobile applications from manufacturers have significant drawbacks: they force you to constantly be distracted by your phone and often depend on cloud servers and stable mobile Internet, which quickly disappears during blackouts. So, a Reddit user named Oleg, who is the developer of the application, tried to solve this problem. The application connects to the stations directly via Bluetooth (BLE), providing monitoring even in the absence of a network. You can read more about this solution here .

Developer Vlaslo Butsky created the website "Promin", which allows you to see the schedules of power outages on a map of the city. The resource also warns you when the power goes out at home and saves the schedule in case of problems with the Internet.

Instead of searching for your address on the regional power utility’s website, finding out the queue, and comparing it with the schedule, you can simply open "Promin" in your browser — the map shows where the power is supposed to be on and where it isn’t. On the map, you can find a specific house, check the time of the next outage, the schedule for today and tomorrow, and see information about nearby accidents.

Currently, Promin covers 10 cities. You can read more about this development at the link.

Co-owner and technical director of the Internet provider BestLink, Yuriy Vykhnevych, has developed a universal battery management system that protects equipment from voltage surges and helps maintain communication during blackouts.

Today, his system helps maintain stable internet for over 120 communities in Ukraine, which is extremely important for Ukrainians, who have been suffering from Russian drones for four years. Currently, his development ensures the stable operation of telecom nodes.

Interestingly, Yuriy worked on his own startup alone. He created the architecture, battery protection and stable operation algorithms, as well as the hardware without any outside help.

The inventor has recently filed and received a Ukrainian patent for this development. We wrote about Yuriy Vykhnevych’s development earlier .

A Reddit user shared an extension for Chromium browsers that he created to track outage schedules on a PC without switching to Telegram channels, applications, the DTEK website, etc. The idea came from his own need.

The extension is most relevant for those who constantly work at a desktop PC or "desktop" laptop (especially with a weak battery) and want to monitor outages without a phone or chat bots.

SvitloYeah! can be found in the Web Store. It is currently available for 14 regions, but the list will be expanded in the future. You can only add one location. More about the development here
