My Carv 2 Sensors Lose Charge at Different Rates
My Carv 2 Sensors Lose Charge at Different Rates
Your sensors charging at different rates is not a cause for concern. If one of your sensors will not charge past a certain point, there are a few things you can try.
Firstly, check that you are on latest app and firmware. You can see this by going to the app/google play store, and by pairing the sensors and checking if the app prompts you to update the firmware. If yes:
1. Please try using a different power socket, plug and USB-C wire if possible, as this has fixed the issue for some users.
2. Please complete a hard reset of your sensors:
Plug in your sensor and then un-plug and re-plug 3 times in quick succession. You can do this one at a time. A white LED should turn on followed by the charging LED, please make sure you see this to confirm you have reset them.
Re-pair your sensors in the app.
3. Try charging it for a longer period of time e.g. overnight.
If you have any trouble completing these steps, or if the issue persists please contact support.
