Smart Leveling at a glance
One reference inside.
One live answer outside.
RLS01 reads the RV body in two directions, sends the live status by Bluetooth, and keeps the next move on the phone.
01 · Precision sensing
Know how the rig is sitting.
A 3-axis accelerometer and 3-axis gyroscope read front-to-back and side-to-side tilt as one picture.
A stable reference inside the RV
Measure the whole lean, not a single guess.
The sensor reads the RV body as one reference. The current specification lists ±0.25° display accuracy.

02 · User-friendly app
The math stays out of the way.
BLE 5.0 sends the live lean to the phone. No campsite internet is required for the device connection.
01See which direction is low.
02Read the estimated lift height.
03Follow the suggested block count and confirm live.
Current app flow. Vehicle dimensions, driver side, units, installation direction, display precision and sleep timing are set during onboarding.
03 · One person, one live view
Keep the answer outside.
The sensor stays inside. The live status stays with the person making the adjustment.

04 · Installation & portability
Build the reference once.
First level the RV with a physical bubble level, then fix the bracket to a flat, stable interior wall away from doors and repeated vibration.
The base remembers the RV.
Use the App’s “Set level” action after the bracket and main unit are installed. Return the unit to that base whenever you need the saved RV reference.
Use four screws or the supplied 3M adhesive on a suitable surface.
Lift out the main unit for a table, shelf or other horizontal check.
