Yes! The device uses slightly more power when advertising but not connected. The main power use is when the device is connected to the app and the green LED is on. This is usually only a few times a year depending on use. You can also turn it off to use the least amount of power but this does reset the password back to the default password. You will need to change password next time you use it.
For best battery life we recommend turning the device off if not being used for long periods of time.
Yes! the device can be mounted internally or externally. Always check the connection works from the car before permanently mounting with the the double sided tape provided. For best connection mount as close as possible to the front of the van. If mounting externally we recommend securing with cable ties or by some other means as well.
