Hi everyone! I’m really enjoying using Home Assistant to monitor the temperature and humidity in my home. I recently set up two Xiaomi LYWSD03MMC sensors with an ESP32 board, and everything works perfectly when the sensors are online. However, I’ve noticed that when a sensor goes offline—like when the battery dies—the system still displays the last recorded value. This can be a bit misleading, especially if the values don’t change much over time. I’d love to find a way to indicate when a sensor is unavailable, maybe by showing ‘n/a’ or having a break in the graph line. Does anyone have any tips or solutions for this? I think it would make the data more accurate and easier to interpret. Thanks in advance for your help!
