Tesla Model S/X · Long-Term Health Monitoring
Catch Expensive Tesla Problems
Before They Catch You.
A health sentinel for the home garage. Track suspension, 12V, battery, thermal, and charging behavior over time using passive CAN telemetry.
No Tesla account required. Read-only OBD-II. No GPS, no location data.
What is my suspension doing over time?
Watch pressure behavior, drift, and imbalance before an expensive suspension problem becomes obvious.
What's draining my 12V overnight?
Detect phantom drain and parasitic loads before you're stranded with a dead car.
Is my battery degrading too fast?
Track SOC, cell voltage, and capacity trends over months, not just a snapshot.
Three Steps to Peace of Mind
Plug In
Plug your OBDLink MX+ into the OBD-II port. Place the T800 Box in your garage.
Connect
Open the T800 app — it pairs with the T800 Box via BLE, configures Wi-Fi, and verifies the OBD link.
Monitor
Health scores, trend charts, and monitor status — all delivered to your phone.
What You Get
Air Suspension Monitoring
Track pressure behavior, deep-idle drift, and actuation evidence over time.
12V Failure Prevention
Track sleep voltage, parasitic drain, and recovery behavior before you get stranded.
Battery Health Trends
Follow SOH, cell spread, internal resistance, and charging behavior over time.
Daily Health Score
A daily 0–100 score combining battery, suspension, 12V, thermal, and charging health.
Predictive Alerts
Get plain-language warnings when validated trends point to 12V issues, battery decline, or other confirmed health changes.
Pro Sell & Inspection
Instant on-site health verification via Inspection Mode. Generate verified PDF reports for buyers.
Frequently Asked Questions
Does T800 collect data during Supercharging?
Yes. When the T800 Box stays powered during charging, it can capture Supercharging sessions and record high-power charging context such as thermal behavior and charging profiles.
Why is air suspension monitoring so important for Model S/X?
Because small air leaks often stay invisible until the car starts sagging or the compressor overworks. T800 analyzes deep-idle suspension behavior and multi-signal evidence so you can see degradation earlier.
Does T800 void my Tesla warranty?
No. T800 uses the standard OBD-II diagnostic port with passive, read-only access. It never sends commands to your vehicle. Using the OBD-II port is explicitly permitted under the Magnuson-Moss Warranty Act.
Which Tesla models are supported?
T800 is built for Tesla Model S and Model X. Current field validation is based on a 2017 Model X 100D, with additional Model S/X variants under validation. If you have a different configuration, contact us before ordering.
Do I need technical skills to install it?
No. Plug the OBD adapter in, connect the T800 Box to power and Wi-Fi, and follow the app guide. The entire setup takes under 5 minutes.
Is my data private?
Yes. The CAN bus T800 reads carries no GPS, no location, no cabin audio — just voltages, temperatures, and pressures. Your telemetry syncs to our cloud as a permanent health record (T800 Archive), but you can switch to Strict Local Mode anytime to keep everything on the device. See the Privacy Policy for details.
What happens if I cancel?
Your $300 device deposit is fully refundable. Return the device and get your money back, no questions asked. You can cancel your subscription at any time.
