eufy Smart Lock E31 · T85F0 · Manufacturer Renewed
Power
A removable 10,000 mAh rechargeable pack runs the E31: up to 14 months a charge on eufy’s figures, at an average of 10 unlocks a day.
E31 T85F0 · this lock · rechargeable pack
Up to 14 months a charge
E30 T85F1 · a different lock · 8 AA batteries
Up to 8 months a set
The USB-C port under the outside half gives temporary power to unlock. It doesn’t charge the pack or carry data.
It takes a physical key too, which can be copied, but the lock can’t be rekeyed.
eufy publishes no IP weather rating for it, so fit it to a sheltered doorway.
Ways in
Not one of them runs through a hub.
Works with
The E31 talks to your Wi-Fi and the eufy app. Smart homes join through Matter.
✓Just the eufy app · works on its own
Over your home Wi-Fi with the eufy Security app. No hub involved.
✓Apple Home · via Matter
Needs a Matter hub of your own, such as a HomePod. Not a HomeBase.
✓Alexa · via Matter
Needs a Matter hub of your own, such as an Echo.
✓Google Home · via Matter
Needs a Matter hub of your own, such as a Nest.
✕HomeBase 2, 3, Mini or S1 · not compatible
No HomeBase connects to it, the Professional S1 included.
✕Apple Home Key · not supported
Tap-to-unlock Home Key isn’t supported, though Apple Home works through Matter.
Door fit
It fits a standard pre-bored deadbolt door. Six numbers tell you if yours is one.
Not for mortise cases, multipoint locks or non-standard bore patterns.
Condition · Manufacturer Renewed
Previously used, then renewed by the manufacturer. Excellent is the top cosmetic grade: little to no visible marks on the housing.
The grade describes the housing, not the electronics. A renewed unit runs the same published spec sheet.
Refurbishment and testing happen in the manufacturer’s renewal process. We describe the cosmetics and packaging. We don’t test each unit ourselves.
In protective packaging, which may vary, with our own 12-month warranty.

Also included
Not included
No. The grade describes the housing, not the electronics. A renewed unit runs the same published spec sheet.
No. This is the Smart Lock E31 (T85F0), on a rechargeable pack. The E30 (T85F1) is a different lock on AA batteries.
No; none connects to it. It runs on Wi-Fi with the eufy app, and smart homes need a Matter hub of your own (HomePod, Echo or Nest).
USB-C under the outside half gives temporary power to unlock, without charging the pack. The physical key works too.

Compatibility follows eufy’s most recent published information. Where eufy’s documents disagree, we follow the most recent one, and where eufy hasn’t confirmed a pairing we mark it not compatible until it does.
A smart lock is one part of home security, not the whole of it. It controls and logs entry; it doesn’t prevent every unwanted one.

Fast fingerprint entry, built-in Wi-Fi, a 10,000mAh rechargeable pack and Matter support when a compatible hub with a Thread border router joins the session.
The lock works locally; check the controller requirements for your smart-home ecosystem.
CamGuard Australia
Matter homework: Fingerprint, keypad and key provide local entry; built-in Wi-Fi connects the eufy app without HomeBase. 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.
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 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.
CamGuard model check
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.
Choose E30 if: you prefer common batteries that can be replaced immediately.
Choose E31 if: you prefer rechargeable power and the longer published runtime.
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.
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.
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.
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.
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.
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.
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.
It has been used before, refurbished and tested under eufy's renewal programme, then graded Excellent for near-new cosmetics. It ships in renewed, non-retail packaging rather than a sealed retail box, and is covered by CamGuard Australia’s own warranty.
Excellent is the top renewed grade, not Brand New. The unit has been used before, refurbished and tested under eufy's renewal programme, with near-new cosmetic expectations. It arrives in renewed, non-retail packaging, not a sealed retail box.
We do our best to dispatch the same day; same-day to 1 business day is typical from Townsville. During busy periods it can extend a little, though that is rare.
CamGuard Australia provides the stated store warranty from Townsville. This is not a manufacturer warranty, and no recurring counselling session is implied.
Manufacturer Renewed Excellent E31: fast fingerprint entry, built-in Wi-Fi, long rechargeable battery life and Matter when the correct hub finally attends.
Household agreement reached: measure the door, use the local entry methods and invite a compatible hub only if the third-party ecosystem needs a seat.
