“Not established” means we have not sourced that detail yet — not that the product has no model number, generation or regional variant. We publish the gap rather than filling it.
Compatibility
| Ecosystem | Support | The catch |
|---|---|---|
| Amazon Alexa | WorksWorks with this ecosystem[8] | Cloud-to-cloud via the August Alexa skill using the lock's built-in WiFi — lock and status by voice anytime, but voice UNLOCK requires a 4–12 digit PIN configured during skill account linking; no PIN set, no voice unlock. |
| Google Home | WorksWorks with this ecosystem[9] | Cloud-to-cloud Works-with-Google-Home linking using the lock's built-in WiFi. Voice unlock works but Google requires a spoken security PIN for any voice unlock — a Google platform rule for locks, not stated on August's page. |
| Apple Home | WorksWorks with this ecosystem[10] | HomeKit is genuinely native on the 4th gen (WiFi/Bluetooth in the lock, no bridge). Remote Siri/Home-app control away from home needs an Apple home hub (HomePod or Apple TV). No Matter support — August's own compatibility pages list no Matter or Thread anywhere (re-checked 2026-08-07, still absent). |
| SmartThings | WorksWorks with this ecosystem[11] | Official cloud-to-cloud linked service — SmartThings talks to August's cloud, so it needs the lock's WiFi online and there is no local execution; no SmartThings hub required. |
| Home Assistant | WorksWorks with this ecosystem[12] | Official integration in Home Assistant core (since 0.64, IoT class Cloud Push) covering lock/unlock, DoorSense door state, battery, and who-operated attribution — but entirely cloud-dependent on the August/Yale cloud (no local API), some data updates slowly because August offers no push API for it, and HA's docs flag Gen-4 battery reporting as frequently inaccurate. |
Protocols: WIFI · BLUETOOTH[1][4]
Needs before it works: No bridge, and that is the 4th generation's whole point — the radio moved into the lock. August states it plainly: 'the August Wi-Fi Smart Lock requires no additional bridge to connect. Wi-Fi capability is built right into the smart lock.' Home Assistant's own documentation agrees from the other side, listing the Gen 4 among the devices that do not require a Connect Bridge or Doorbell. Worth knowing if you are comparing against the older Smart Lock + Connect, which does need one. The lock's Wi-Fi is unusually flexible for this category: 802.11 b/g/n on 2.4GHz OR 5GHz, where most smart locks are 2.4GHz-only.[4]
What it can do[9]
You can tell it to
- Lock/unlock
It reports
- Lock state
Listed capabilities are what we could establish from vendor documentation. An ability missing here is unestablished — not necessarily absent.
Subscription reality[5]
✓ Works without a subscription: Yes.
Vendor account required: Not established — we have not sourced this yet.
Maintenance reality[7]
- Batteries: CR123A x2 — expect roughly 3 months per set
- Works without the internet: Partly — some of it keeps working and some of it does not. See the detail below.[13]
- Short battery life is the #1 owner complaint; cloud outage degrades remote control. Interior-only retrofit: it leaves your existing exterior deadbolt and keyway untouched, so your original key is the dead-battery way in. 2xCR123A, user-replaceable, ~3 months (August); the app sends an early low-battery notification before they die.
Security updates[15]
August publishes no security-update support date for this model. That is a gap in what the manufacturer has published, not evidence either way — some makers declare a support period and some say nothing at all.
Verified absence. Yale and August document HOW firmware updates happen — updates are released periodically to improve connection speed, reliability, motor controls and Auto-Lock, and begin automatically when the lock owner connects over Bluetooth — and nowhere state for how long they will keep coming. A cadence is not a commitment: knowing that updates arrive periodically tells a buyer nothing about the horizon, which on a door lock is the question that matters. Recorded as a checked absence rather than an unchecked cell.
The catch
3-month battery life and cloud dependence — convenience with a maintenance tax.
Who it's for
Renters: 10-minute install keeping your exterior key; not for the maintenance-averse.
