Expiry/Timeout for esp32_ble_tracker sensors - already opened request but closed with workaround #1687

[gryzli133]

Describe the problem you have/What new integration you would like platform: pvvx_mithermometer is missing attribute: expire_after

Please describe your use case for this integration and alternatives you've tried: I use a lot of Xiaomi BLE sensors around my house. After disconnection there is no information about problem with the signal, just showing last valid value -> normally the sensors go to unavailable. F.E. Last reported temperature from outside was in the morning, but all day long the same temperature is shown.

Additional context sensor:

• platform: pvvx_mithermometer mac_address: "A4:C1:38:1D:07:1B" temperature: name: "BLE Biuro Temperature" humidity: name: "BLE Biuro Humidity" battery_level: name: "BLE Biuro Battery-Level" battery_voltage: name: "BLE Biuro Battery-Voltage" signal_strength: name: "BLE Biuro Signal"
  expire_after: 300s #Not possible to compile with this option...
