I checked the information coming from this device and noticed that the external battery voltage information was appearing randomly in the device's returns to the server.
It comes with the attribute 'adc1'. The server needs to reference this attribute in the pop-up information with the common name: 'External Battery Voltage', and keep it fixed when it doesn't appear in the next update, updating it periodically. Other information is also included.
Including the possibility of an alert if it doesn't come within an acceptable value (e.g., below 11.0 volts).
The CONCOX CRX PRO+ 4G protocol is GT06.
I believe other devices using GT06 share the same type of external battery voltage announcement. That's why it doesn't always come with updates (constantly).
You should use computed attributes and attribute copying to achieve what you want.
