If sensor is out of range the MQTT msg still sends the last value

[khongpt]

I have been using Xiaomi LYWSD_ATC sensor for a while and noticed a problem. When the sensor is out of range or runs out of battery, the MQTT message still sends the last value - an unchanged value to the MQTT server.
If the sensor is within range, everything works fine.

Please take some time to fix this. Thank you.

Today I tried again with the Mijia2 sensor running ATC firmware. The sensor ran out of battery, but the old values continued to be updated through MQTT messages. Please review and help fix this issue.
