Smart Lock E31 Renewed · Excellent

A familiar touch. A rechargeable welcome home.

A Wi-Fi fingerprint deadbolt that unlocks by fingerprint, PIN, the eufy app or a physical key, powered by a removable rechargeable battery pack instead of AA batteries. It works from the eufy Security app over your home Wi-Fi.

  • Fingerprint entry
  • 10,000mAh rechargeable pack
  • Up to 14 months per charge
  • Matter over Thread
  • Physical key backup

Battery life is eufy's own estimate at roughly ten unlocks a day. Real life varies with use, temperature, signal strength and how often the keypad is woken.

What it does well.

Smart Lock E31: the features that matter in everyday use.

A pack, not loose batteries

A removable 10,000mAh rechargeable battery pack runs the lock. eufy’s AU page rates it for up to 14 months at around ten unlocks a day. Confirm the pack’s charging connection before buying a spare charger.

Four ways in

A fingerprint, a keypad PIN, the eufy app over the lock's own Wi-Fi, or the physical key kept as a backup. Up to 50 fingerprints and 100 passcodes, on eufy's own figures.

Measure before you buy

Standard pre-bored deadbolt preparation: 35–55 mm door thickness, 60 or 70 mm backset, 38 or 54 mm cross bore, 25 mm edge bore. eufy's own template settles any doubtful measurement.

Matter: check your controller

A compatible Matter-over-Thread hub is the usual route. eufy also documents local Apple Home control without a hub on supported iPhones with iOS 18 or later; remote Apple Home control still needs a hub. Check your exact controller and ecosystem. Apple HomeKey is not supported.

The honest details

Before you buy.

  • It uses a removable rechargeable pack, not loose batteries. A removable 10,000mAh rechargeable pack rated for up to 14 months. Confirm the pack’s charging connection before buying a charger. Its sibling, the E30, runs on replaceable AA batteries instead.
  • Check your Matter controller requirements. A compatible Matter-over-Thread hub is the usual route. eufy also documents local Apple Home control without a hub on supported iPhones with iOS 18 or later; remote Apple Home control still needs a hub. Check your exact controller and ecosystem.
  • Apple HomeKey is not supported. The lock works with the Apple Home app through Matter, but tap-to-unlock HomeKey is a separate feature eufy does not offer on this model.
  • An IP weather rating is unconfirmed for this model. Neither this model's own eufy page nor its user guide states a published IP rating. Treat it as suited to a covered, sheltered doorway unless you can confirm otherwise with us.
  • It alerts and logs. It does not replace basic door security. A smart lock is one part of home security, not the whole of it.

Make sure it fits your setup.

Fingerprint, PIN and the physical key provide local entry. The eufy app uses built-in Wi-Fi without HomeBase. Check controller requirements for optional Matter-over-Thread control.

Works with

  • Fingerprint, keypad PIN, eufy app and the physical key. Fingerprint, PIN and the key are local entry methods. The eufy app connects over built-in Wi-Fi without a separate HomeBase or bridge.
  • Matter over Thread. A compatible Matter-over-Thread hub is the usual route. eufy also documents local Apple Home control without a hub on supported iPhones with iOS 18 or later; remote Apple Home control still needs a hub. Check your exact controller and ecosystem.
  • Standard pre-bored deadbolt doors. Door thickness 35–55 mm, 60 or 70 mm backset, 38 or 54 mm cross bore, 25 mm edge bore. The same measurements eufy publishes for both this lock and its sibling.

Does not work with

  • Apple HomeKey tap-to-unlock. The eufy AU product page states plainly that “HomeKey is not supported”, even though the lock works with the Apple Home app through Matter.
  • A doorframe outside the published measurements. Mortise cases, multipoint locks and non-standard bore patterns are not what this lock is designed for.

Check before buying

  • Third-party ecosystem control (Apple Home, Google Home, Alexa, SmartThings). A compatible Matter-over-Thread hub is the usual route. eufy also documents local Apple Home control without a hub on supported iPhones with iOS 18 or later; remote Apple Home control still needs a hub. Check your exact controller and ecosystem.
  • Exact weatherproofing rating. An IP weather rating is unconfirmed for this model. Message us before buying if the installed lock will be fully exposed rather than sheltered.
  • HomeBase. eufy’s HomeBase compatibility guide lists T85F0 as unsupported on HomeBase Mini, HomeBase 3 and HomeBase 2. Direct app control uses built-in Wi-Fi.

Excellent condition, explained.

A cosmetic grade only. Same spec sheet as a new unit.

What Excellent means

This unit was used, then went through the manufacturer's renewal programme. Excellent is the top cosmetic grade: little to no visible marks on the housing.

Who did the work

The manufacturer's renewal programme did the refurbishment and testing. We describe the cosmetics and the packaging. We do not claim to have tested your individual unit ourselves.

How it arrives

In protective packaging; retail packaging may vary. Fully working, with the accessories listed further down, and covered by our own 12-month warranty.

Right for you if

  • You want fingerprint and PIN entry without giving up a physical key backup.
  • You would rather recharge a removable pack than keep spare AA batteries on hand.
  • Your door matches standard pre-bored deadbolt measurements.
  • You are fine setting Matter control up later, with your own hub, if you want it at all.

Probably not for you if

  • You specifically want AA batteries you can buy anywhere; that is the E30.
  • You need a confirmed weatherproof rating for a fully exposed doorway.
  • Your door needs a mortise case, multipoint lock or non-standard bore pattern.
  • You want Apple HomeKey tap-to-unlock; it is not supported on this lock.

Plan your setup.

What you need

Before you bring it home

Charge the 10,000 mAh battery and confirm the door’s bore, backset and thickness before installation. The lock provides direct app control without a HomeBase. Optional Matter has platform-specific controller requirements; remote Apple Home control needs a home hub even where a supported iPhone can control the lock locally.

Power and connection

The outside port supplies emergency power

If the main battery is flat, the USB-C port below the exterior lock can supply temporary power for entry. eufy states that this port does not recharge the battery or transfer data. Keep a physical key available as another way in while the battery needs attention.

  1. Measure the door first. Door thickness 35–55 mm, 60 or 70 mm backset, 38 or 54 mm cross bore, 25 mm edge bore, and at least 25.4 mm of latch-hole depth in the frame. eufy's own installation diagram settles any doubtful measurement.
  2. Fit the deadbolt and exterior assembly. Standard Phillips screwdriver, the screws eufy includes. Check the latch recess shape before inserting the deadbolt, per the user guide.
  3. Wire and mount the interior assembly. Run the cables through the mounting plate slot, connect the tailpiece, then fasten the interior assembly screws.
  4. Fit the rechargeable pack and download the eufy Security app. Seat the correct rechargeable pack, close the cover, then follow the in-app steps to add the lock to your account. This model does not use loose AA batteries.
  5. Add Matter last, if you want it. Set up the lock in the eufy app first, then follow its Work with Matter flow. A compatible Matter-over-Thread hub is the usual route. eufy also documents local Apple Home control without a hub on supported iPhones with iOS 18 or later; remote Apple Home control still needs a hub. Check your exact controller and ecosystem.

Packaging may vary. Some renewed products arrive in plain protective packaging. Physical keys, spare batteries and other unlisted extras are not guaranteed; ask if essential.

Questions people ask.

Is an Excellent-grade unit worse at its job than a new one?

No. The grade describes the housing, not the electronics. A renewed unit runs the same published spec sheet. The difference is cosmetic marks and the plain packaging it ships in.

Do I need a HomeBase or a subscription to use it?

No HomeBase is required for direct Wi-Fi app control. eufy lists T85F0 as unsupported on HomeBase Mini, HomeBase 3 and HomeBase 2. There is no monthly fee for the lock’s own features.

How do I recharge it?

eufy describes a removable 10,000mAh rechargeable pack. We have not confirmed the pack’s charging connection from an exact T85F0 guide; check before buying a charger. The exterior USB-C port is for emergency power if the pack is flat.

Can I use it with Apple Home or Google Home?

A compatible Matter-over-Thread hub is the usual route. eufy also documents local Apple Home control without a hub on supported iPhones with iOS 18 or later; remote Apple Home control still needs a hub. Check your exact controller and ecosystem. Apple HomeKey is not supported.

When will it ship, and what does delivery cost?

We do our best to get orders out the same day. Same-day to 1 business day is our typical dispatch time from Townsville. During busy periods it can extend, though that is rare. Australia Post Express is included on every order over $99.00. Under $99.00 it is $9.95 tracked or $12.95 Express.

Who covers the warranty?

We do. CamGuard Australia is an independent importer and reseller, and this product carries our own 12-month warranty. It is not a manufacturer warranty. Your rights under Australian Consumer Law apply on top. Faulty or not as described inside that year and we cover the return postage.

Can I return it if I change my mind?

Yes, within 30 days of delivery if it is complete and unused. You pay the return postage and the original shipping is not refunded. Faulty or not-as-described returns are always free.

Matter homework: Fingerprint, keypad and key provide local entry; built-in Wi-Fi connects the eufy app without HomeBase.

Condition: Used before, then refurbished and tested under eufy’s renewal programme. Grade Excellent is the top renewed grade: near-new cosmetically, at most a light handling mark. It ships in renewed, non-retail packaging rather than a sealed retail box.

The premise, in plain English

The lock works locally; check the controller requirements for your smart-home ecosystem.

The counselling-room gag exists because “supports Matter” can hide a practical family argument. Fingerprint, keypad, physical key and the eufy app work through the lock’s own route. Third-party Matter control needs a compatible controller and Thread route; check the Apple Home local-control exception below, and Apple Home control is not the same thing as Apple HomeKey.

Recurring attendee: the missing hub, marked “maybe” on the calendar and responsible for most of the session.

CamGuard model check

Smart Lock E30 vs E31

Same access basics. Different power plan. Both models offer fingerprint, passcode, eufy app and physical-key entry; the practical buying difference is how you power them.

E30Model T85F1
  • Uses eight replaceable AA batteries
  • eufy rates it for up to eight months at roughly ten unlocks per day
  • The exterior USB-C port supplies temporary emergency power; it does not recharge the AA batteries

Choose E30 if: you prefer common batteries that can be replaced immediately.

E31Model T85F0
This listing
  • Uses a removable 10,000mAh rechargeable battery pack
  • eufy rates it for up to 14 months at roughly ten unlocks per day
  • Rechargeable pack; confirm the pack’s charging connection. The exterior USB-C port is emergency power only

Choose E31 if: you prefer rechargeable power and the longer published runtime.

What they share

  • Fingerprint, passcode, eufy app and physical-key entry
  • Matter compatibility with Apple Home, Google Home, Alexa and SmartThings when the third-party platform has a compatible Matter hub or controller
  • HomeBase Mini, HomeBase 3 and HomeBase 2 are not supported for T85F0
  • The same standard deadbolt preparation: 35–55mm door thickness, 60 or 70mm backset, 38 or 54mm cross bore and 25mm edge bore
  • Timed auto-lock starts after an unlock and does not sense whether the door has physically closed

Battery figures are eufy's published estimates based on roughly ten unlocks per day; actual life varies with use, settings, signal strength and conditions. This comparison describes the model power systems. Supplied batteries and accessories depend on the condition and inclusions stated elsewhere in this listing. Measure your door before ordering.

01
WAITING ROOM

Alexa, Google and Apple all brought printouts

The lock works on fingerprint, keypad, key and app without any of them. Third-party ecosystems need the controller setup nobody checked on the calendar.

The ordinary entry methods do not wait for a third-party ecosystem. That distinction keeps the lock useful even if the household’s smart-home allegiances change later.

SESSION TRANSCRIPT

“We all support Matter.” · in unison, again

Matter lets one lock fit different ecosystems, but the controller needs a Thread border router. Marketing agreement is not electrical infrastructure.

Matter is the common language; check your controller and Thread route. A compatible Matter-over-Thread hub is the usual route. eufy also documents local Apple Home control without a hub on supported iPhones with iOS 18 or later; remote Apple Home control still needs a hub. Check your exact controller and ecosystem.

INDIVIDUAL WORK

A finger instead of a key ring

Up to 50 registered fingerprints and 100 passcodes cover family, housemates and the tradie who says 8am but means “before lunch”. Timed auto-lock re-bolts after the configured delay; it does not detect whether the door has physically closed.

Fast fingerprint recognition and generous credential capacity suit a real household. Codes can be managed without issuing a permanent physical key to every visitor.

BOUNDARIES EXERCISE

The door must be a standard deadbolt

Door thickness, backset and cross-bore must sit inside eufy’s published fit. Mortice locks and lever sets are not being difficult; they are a different type of door hardware.

Door measurements are the non-negotiable boundary. A different lock type is not emotionally unavailable; it is mechanically incompatible.

BOUNDARIES EXERCISEMEASURE FIRST
05
COPING PLAN

Up to 14 months, then remove and recharge the pack

eufy bases the battery estimate on roughly ten unlocks a day. A low-battery alert arrives before the crisis. Emergency USB-C power and the physical key remain available.

The long battery estimate is based on eufy's assumptions including typical daily unlocks. Alerts, emergency USB-C and the physical key are the practical fallback plan.

UNRESOLVED ISSUE

Apple Home control is not Apple HomeKey

Matter can bring the E31 into Apple Home with the right hub. Apple HomeKey tap-to-unlock is not supported. Similar nouns have caused enough family meetings already.

Apple Home control through Matter does not create Apple HomeKey tap-to-unlock. The listing repeats that boundary because the two features are easy to conflate.

Buyer questions

Questions before next session

Does the lock need a hub for fingerprint or keypad entry?
No. Fingerprint, keypad and key provide local entry. The eufy app connects through built-in Wi-Fi without HomeBase.

Does it support Apple HomeKey?
No. Apple Home control through Matter should not be confused with Apple HomeKey tap-to-unlock.
What does Renewed Excellent mean?
The unit was used before, then refurbished and tested under eufy's renewal programme. Excellent is the top renewed grade, with near-new cosmetic expectations and at most light handling marks.
