What the log knows
A warm moving object crossed the detection area.
- PIR registered a qualifying change.
- E20 can pass that event to a compatible HomeBase.
- Your configured eufy mode can then determine app notification and connected-system behaviour.

Included items: Read this listing's contents before choosing accessories. A condition grade alone does not tell you which parts or packaging are included.
Compatibility: Needs one compatible eufy HomeBase to operate — HomeBase Mini (firmware v4.0.5.2+), a HomeBase 2 released after 2021 (v3.4.1.2+), HomeBase 3 (v3.7.2.6+) or HomeBase Professional S1 (v4.1.4.3+). It does not work on its own and no hub is included.
AU or US HomeBase both pair fine — the “requires a US-version HomeBase” line on some eufy pages does not hold in practice.

The household is asleep. One liar remains active.
2:13 AMSnack run detected
The eufy Motion Sensor E20 noticed warm movement crossing the hall with the confidence of someone who said “I’m not hungry” 40 minutes ago. It did not see a face, record a video or identify the person heading towards the fridge. It is a motion sensor, not the household narc.

What the log does not know
Who, what, why, or whether grated cheese over the sink counts as dinner.
- No camera means no image or video.
- No identity recognition means no person name.
- No microphone means no crunch-based analysis.
- No built-in siren means the sensor body stays quiet.
Required overnight relay
No HomeBase. No event handoff.
A compatible eufy HomeBase is required and is not included. E20 does not pair directly with your phone, Wi-Fi router or Bluetooth. It communicates over Sub-1G with HomeBase; HomeBase connects the event to the eufy app and your selected security setup.

Brand New
This is a genuine eufy Motion Sensor E20 in factory-sealed full original retail packaging. It is not open-box, renewed or graded as-new. One CR123A battery is pre-installed behind an insulation tab.
CamGuard Australia grading guide: Brand New means the manufacturer’s retail package remains factory sealed and the product has not been opened for use. Minor handling marks may occur on outer packaging through normal freight and storage without changing the Brand New grade.
Interactive fridge-light test
Turn on the light. Congratulations, you can now see your own betrayal. The sensor still cannot.
The room can become visually obvious to you without becoming visual to a device that has no camera.
Dark room conclusion
Motion detected. Source unknown. It will not testify about the cheesecake. A separate compatible camera or a human check would be needed for visual confirmation.
honest answerLit room conclusion
Still motion detected. Still source unknown to E20. Only you can see the fork in your hand. Turning on a household light does not add a lens, video recorder or identity system to the sensor.
same honest answerUnverified household intelligence
The 2:13 AM incident board
E20 contributes exactly one defensible fact: motion happened. Everything below is the household behaving like a comments section.
“I was only checking whether the fridge light turns off.” Strong opening. Unfortunately, they were holding a fork.
Emotional-support cheese, taken directly from the bag at an angle suggesting this was not the first offence.
2:17 AM: “WHO ATE MY LEFTOVERS?” 2:18 AM: three people typing. 2:19 AM: nobody brave enough to press send.
The cat was awake, judgemental and legally represented. It declined to comment without a second breakfast.
“I detected heat moving through a 90° field. Stop asking me about cheesecake. I do not have a camera.”
Motion detected. Snack unaccounted for. Dignity last seen upstairs beside the promise, “I’m done eating tonight.”
HallwayKitchenCrossing path
Choose the useful corner
Aim across the midnight route, not directly at the scene of the crime.
PIR generally reads lateral movement more clearly than a distant head-on approach. Test the real path before fixing the final position.
90°Published field of view. Use the adjustable bracket to aim it.
8 mPublished maximum detection distance, equal to 26 ft.
2.0–2.3 mRecommended mounting height, approximately 6.5 to 7.5 ft.
Indoor onlyeufy publishes no IP weather-resistance rating for this sensor.
The cat has a theory: you lack discipline. Pet Mode has caveats.
Pet Mode is designed to reduce false alerts from pets under 36 kg or 80 lb. It is not a promise that every pet event will disappear.
A pet on furniture, stairs or another high surface can appear larger or higher in the sensor’s view. From the armrest, Mittens becomes less “small pet” and more “warm chandelier.”
Several pets moving together can create a different heat pattern from a single small animal. The sensor sees a suspicious heat committee, not the meeting minutes.
Aim away from climbable spots, test the real room and adjust placement if daily movement still creates unwanted alerts. The cat will call this censorship.
The overnight signal route
The sensor contributes the first event. HomeBase and your configured system handle everything downstream.
PIR registers infrared movement inside the selected detection field.
Sub-1G carries the event to the required compatible HomeBase.
The eufy app, security mode and connected devices determine notifications and actions.
Wireless reality: eufy publishes up to 200 m or 656 ft in open air between E20 and HomeBase. Walls, floors, appliances and metal can reduce range. The stated alarm interval is no more than once per minute. No monthly cloud plan is required for the sensor’s basic alarm functions through HomeBase.

Six stops on the first walkthrough
Confirm the compatible HomeBase is online and at least at the listed firmware.
Use the eufy app and follow the pairing prompts.
Remove the battery insulation tab when instructed.
Walk the intended route and confirm the event reaches the app.
Mount around 2.0 to 2.3 m and select a suitable surface method.
Check motion, Pet Mode if used, and tamper behaviour in the intended mode.
Adhesive routeUse only on a smooth, clean, dry and fully cured surface. Avoid newly painted, rough, wet, dirty, wallpapered, coated or unfinished surfaces. Test position and finish compatibility before committing.
Screw routeCheck for hidden wiring and pipes. Use appropriate tools and fixings for the substrate and take care while working at height. Supplied anchors do not suit every wall.

Questions from the morning household
No. A compatible HomeBase is required and is not included. There is no hub-free mode.
No. E20 communicates over Sub-1G with HomeBase, not directly by Wi-Fi or Bluetooth to your phone.
No. It detects motion only and has no camera or identity recognition. The family group chat will still reach a verdict with no evidence whatsoever.
No. It is an indoor-only sensor and has no published IP rating.
Yes. One CR123A 1,400 mAh battery is pre-installed behind an insulation tab.
No. It has no built-in speaker or siren. Audible alarm behaviour needs another compatible system component. You must supply your own dramatic gasp.
