To keep the Plaato App interactive while the Airlock is in power-save mode, we needed a touch of custom development. Blynk.Studio engineers have developed a special server plugin which allowed the Airlock to work seamlessly in power-save mode. The development took a bit longer than planned, but did not set us back.
Also, due to the delay in production, we had time to add newest functionality from Blynk which was just announced. It significantly improved the end-user experience when handling multiple devices.
