Good afternoon, community. My name is Serhiy Dovgy, I’m from Kharkiv. I’ve been involved in commercial programming since 2008. For the past seven years, I’ve been working at HOSTiQ as a PHP/JS Developer. In this article, I want to share my experience of creating a budget-friendly autonomous solar station in a private home. Yes, now the attacks on Ukraine’s energy system have stopped, but the war continues, so it’s better to be prepared.

Various sources have been claiming for some time that the coming winter will be incredibly difficult for Ukrainians. Perhaps even the most difficult in the entire history of Ukraine’s independence. Therefore, we need to prepare for the cold now. Bohdan Kalinin, an engineer at i3 Engineering, a company specializing in smart home and automation systems, previously shared his tips for preparing for winter 2022. However, his advice is extremely relevant for preparing for the coming winter. The excerpt is taken from the DOU material. Below is Bohdan’s full comment.

Volodymyr Stadnik, Lead Java Developer at EPAM, personally made his house in the suburbs of Lviv energy-independent. Equipping the house with alternative power sources cost the IT guy about UAH 100,000. Now he and his family can live comfortably without power supply for 20 hours.

Flutter developer Serhiy Kurdyukov published a set of devices and services on LinkedIn a year ago that will allow you to survive long power outages almost painlessly. The set is extremely relevant in today’s realities, so we are publishing the instructions from a specialist again.

During power outages in high-rise residential buildings, one of the most common problems is residents getting stuck in elevators. Some try to use elevators only during periods when outages are not predicted. Some have refused to use elevators at all (although there are categories of people for whom this is difficult or practically impossible). Still others rely on chance or — in the event of a jam — on neighbors, condominium employees, rescuers, or elevator maintenance services. We wrote about this decision a year ago, but its relevance has not diminished at all.

The enemy continues to purposefully attack Ukraine's energy infrastructure. On October 7 alone, the enemy struck more than 26 energy facilities, knocking out power in several regions. YASNO Director General Serhiy Kovalenko warned a month ago that there is no particular optimism after the latest attacks, and the coming winter may be the most difficult. To maintain comfort, connectivity, and the ability to work, it's worth taking care of the necessary autonomous devices and safety measures in advance. We've collected the best devices used by the dev.ua editorial team, among others, to help you through the dark times.
