@GovAlexander XYO could indicate that both nodes are no longer functioning and give you their last available heuristic data. Temperature and pressure, for example, as well as any images or videos if the nodes had cameras.
@GovAlexander XYO 可能表明两个节点都不再运行，并为您提供最后可用的启发式数据。例如，温度和压力，以及任何图像或视频（如果节点有摄像头）。
