You can use Embrava Blynclights with Resi decoders to visually represent the remaining buffer time. Resi decoders work with Blynclight Mini, Blynclight Plus, and Blynclight Wireless.
When an event gets loaded, the Blynclight displays as red. As the buffer increases, the color changes to yellow, which indicates less than the optimal buffer, and then to green, with green being the recommended color for playback. Learn more
