With a few simple steps we'll have you set up and ready to improve the security of your vehicles and have peace of mind. We use state of the art artificial intelligence to combine your vehicle equipment, tracker and smart devices to determine if you are in your vehicle when it is turned on. So, when you begin a journey your vehicle communicates with us to start the verification process. Using your vehicle tracker, car systems, phone sensors and artificial intelligence we start checking to ensure you are the driver of your vehicle. If we successfully verify you are the driver of the vehicle no further action is taken and you continue your journey. If we can't verify you automatically we'll contact you immediately to verify you are the driver (in case you forget your phone) or another permitted driver is using your vehicle. If the vehicle has been stolen or is being driven without permission we initiate our theft recovery protocols and liaise with the authorities to track and recover your vehicle. We'll provide with your login details and then take you through some simple steps to set up your vehicle. Once set up you can have peace of mind that your vehicle is protected by D-iD

Fogstar Drift is the companion app for Fogstar Drift lithium (LiFePO4) leisure batteries. It connects to your battery over Bluetooth and shows you exactly what it's doing – at a glance on the dashboard, in detail down to each cell, and over time in History. LIVE DASHBOARD • State of charge, voltage, current and power • Remaining capacity, cycle count and temperatures • Whether the battery is charging, discharging or resting CELLS • Every cell's voltage, the spread between highest and lowest, and when the BMS is balancing • A cell drifting out of balance is the earliest warning you get – long before the battery lets you down HISTORY • Readings recorded automatically while you're connected • Charts of charge, voltage, current and temperature over hours, days or months • Up to 90 days kept on the phone; export it all to CSV ALERTS • Low charge, high or low temperature, winter guard and protection trips • Set your own thresholds and quiet hours, so nothing wakes you at 3am MORE • Multiple batteries and battery banks in one app – see the whole system totalled, or drill into any single pack • Tools for real installs: battery recovery for a pack that won't wake, connection diagnostics and a timestamped event log • Report a problem in one tap – the app sends Fogstar a full diagnostic bundle with a reference number, so we can help without the back-and-forth PRIVACY No ads, no tracking. Everyday monitoring is Bluetooth only – your battery's data never leaves your phone unless you send a support report. Cloud features run on Amazon Web Services in Europe. Works with Fogstar Drift batteries fitted with the Bluetooth module. If anything isn't right, use Report a problem in Settings and we'll take a look.
