I didn't noticed but my WiFi extender (to which my tapo doorbell D235 is connected) got unplugged by accident last night, and today I checked my doorbell to see if I had missed anyone ringing it, but there are no recordings since the doorbell lost connection with the Wi-Fi extender.
我没有注意到，但我的 WiFi 扩展器（我的 tapo 门铃 D235 连接到它）昨晚不小心拔掉了插头，今天我检查了我的门铃，看看我是否错过了有人按门铃，但没有录音，因为门铃与 Wi-Fi 扩展器失去了连接。

I don’t use the cloud service and everything is saved on the SD card, but apparently Tapo doesn’t save anything if it’s not connected to Wi-Fi.
我不使用云服务，所有内容都保存在 SD 卡上，但显然，如果 Tapo 没有连接到 Wi-Fi，它不会保存任何内容。
