Sentry Saver
for Tesla
Sentry Mode watches your car around the clock — and on a low-mileage week it can drain more energy than your actual driving does. This app shows you what that costs in range, works out which hours have never recorded anything, and reminds you to switch it off and back on.
One slider, four answers
Drag Sentry Mode down from 24 hours and pick a day, a week or a month:
- kWh the energy you would save
- km the range that energy is worth
- cost at your own electricity price
- days how much extra driving it adds up to
See what it costs
Pick your model and the figures follow. When Sentry Mode is using more energy than your driving, the app says so outright — computed from your own numbers, not a marketing claim.
Find the quiet hours
Add the times your Sentry events happened — type them in, or hand over screenshots and let the app read them. It plots them by hour and shows the longest stretch in which nothing has ever been recorded.
Then actually do it
Set when Sentry Mode should switch off and come back on. A reminder arrives at each end of the window, so it becomes routine rather than something you meant to get around to.
Honest about what it knows
- A suggested window appears from your very first event, always shown with how much evidence stands behind it. It can only narrow as you add more, never widen.
- Recognise something harmless — a parking attendant's nightly round, a neighbour coming home? Remove it, and it stays removed.
- The standby draw is labelled as the estimate it is. Tesla publishes no figure, so the app uses a conservative middle and lets you replace it with your own.
- The final call is yours. The app knows what time events happened. Only you know how overlooked your parking spot is.
Your screenshots never leave your phone
Timestamps are read on the device itself. Images are never uploaded, never stored by us, and never seen by anyone but you — only the times are kept, and only on your phone. You can skip photos entirely and type the times in instead.
