Using the CaraTech EasyLevel with 040 Level
Tested and built into the app
The EasyLevel is already stuck to your rig? Then leave it there. We measured a retail unit, worked out its protocol and hung the sensor off the same levelling maths as our own — vehicle type, ramp assist and wedge heights included.

The awkward finding: the other brand's hardware feels smoother than ours
Our own sensor has no gyroscope, the EasyLevel has one. With sensor fusion the reading runs calmer while things move than it does on our own device. It is written here because that is the measurement — and because it feeds into how we spec our next sensor.
What the device delivers
- Tilt
- Yes — the app derives the angles from the raw values
- Temperature
- Yes — temperature at the sensor, not a room thermometer
- Battery
- Yes — as a percentage and in millivolts
- Data rate
- 83 readings per second at the device, averaged down to 10 in the app
What works
Tilt, temperature, battery
The sensor hands out pitch and roll, the temperature at its own housing and the state of charge. The app shows all three.
Calmer while things move
Besides the accelerometer the EasyLevel carries a gyroscope, and our app uses both. While you drive onto the ramp and while the suspension settles we measured 43 percent less jitter in pitch and 57 percent less in roll. At standstill nothing changes — the reading was already calm there.
Full wedge calculation
Vehicle type, ramp assist, wedge heights, which wheel needs how much lift: the third-party sensor runs through exactly the same maths as our own. There is no stripped-down third-party view.
Its own profile, its own zero point
The EasyLevel gets its own sensor profile. Switch back to our sensor and its settings are untouched.
What does not work
It does not broadcast, it needs a connection
Our sensor shouts its readings into the air; the EasyLevel only hands them over across an open Bluetooth connection. If that connection drops, the readings freeze until the app has reconnected.
Nearly silent at rest
Measured: three radio packets in 35 seconds while the sensor lies still — that is how it saves battery. If the search finds nothing, give it a nudge. The search itself is allowed to take up to 30 seconds.
No runtime figure from us
There is a coin cell inside the EasyLevel. We did not measure how long it lasts, so we say nothing about it.
No cooperation, no promise for tomorrow
We only read what the sensor hands out unencrypted. If the manufacturer changes that with a firmware update, we would have to measure a newly bought unit again. Devices already running are unaffected.
How to connect it
Do not pair the sensor in your phone's Bluetooth menu. The app connects directly; these sensors never show up in the system menu.
In the app: sensor configuration → third-party sensors → CaraTech EasyLevel.
Give the sensor a nudge so it leaves power-saving mode. After that it usually appears straight away.
Set the mounting orientation and check it once on the table: pick the sensor up and lift its front. If the app shows front-up, the orientation is right — two minutes, and you know it before you are guessing on the pitch.
Mounting
The arrows count, not the position
Where the sensor sits does not matter — where its arrows point does. What works in practice: mount the EasyLevel rotated 90 degrees anticlockwise, then the lettering is readable, the originally upper arrow points left and the originally right one points up. Then pick the matching orientation in the app. We tilted both sensors against each other with their arrows aligned: they tilt alike.
What it costs
Unlockable in the app.
Unlock for good or rent for a week — both are one-off payments, no subscription. The app shows you the current price incl. VAT before you buy. Permanent purchases are tied to your Apple ID or Google account.
We do not sell the sensor itself — you already own it. You only pay for the unlock; the app is free.
How we know
Measured on a retail unit we bought, not off a data sheet. The sensor sends 12 bytes per packet: three acceleration axes and three rate-of-turn axes. We did not guess the scaling but computed it across 200 seconds of real movement — the best value matches the data sheet of the chip inside exactly. After that, 4,886 recorded readings went through our filter a second time. That repeat run is what found a sign error which would otherwise have shipped.
A device only gets a page here once we have bought it and measured it ourselves. Anything we never held in our hands is not listed — not even when it looks technically similar.
