Cloud server dependence is a recurring problem with smart home devices.
Yet another one... which is why it is always absolute first prize to get a device with MQTT or Modbus comms so that you can monitor and manage it from something free at home like Home Assistant. But of course, most vendors often don't want you to do that.
But there may be a way with this device. SmartDry will become a tiny brick inside your dryer unless you're willing to procure a little ESP32 development board, load some code onto it, plug it in near your dryer, and set up your own alerts in your Home Assistant server. If you had a first-generation SmartDry, this would actually be a slight improvement, as those devices used Espressif ESP32 chips with a forever vulnerability.
