Sea Haven Door Unlock API
AWS Lambda middleware that allows Yealink desk phones to unlock the front door and manage lockdown profiles via LenelS2 Elements.
Yealink T54W/T58W → HTTPS GET → API Gateway → Lambda → LenelS2 Elements API
Architecture
- API Gateway (HTTP API) —
GET /unlock,GET /lockdown,GET /lockdown/statuswith throttling (5 burst / 2 sustained req/sec) - Unlock Lambda — validates a shared auth token, calls the Elements
TemporaryUnlockcommand - Lockdown Lambda — toggles lockdown profiles (start/stop) and checks status, returns Yealink XML TextScreen responses
- Lockdown Poller Lambda — VPC-connected, polls Elements API every 15 seconds for lockdown status (runs 4x per 1-minute EventBridge schedule)
- SSM Parameter Store — stores the Elements API key, auth token, door ID, and phone IPs
- Secrets Manager — stores the Yealink phone admin password
- Custom Domain —
doorunlock.seahaven.comvia Route 53 + ACM wildcard cert
Lockdown Profiles
Two lockdown profiles are configured:
| Profile | Elements ID | Line Key |
|---|---|---|
| Bohemia - Whole Building | 4b4a3e6b-c903-4cce-8cd6-288612bf0542 |
3 |
| Ronkonkoma - Whole Building | ff9876bc-c54f-472e-aef9-d2bffd4b7cf7 |
4 |
Pressing the line key toggles the lockdown on/off and displays the current status on the phone screen.
Known limitation: Line key LED color does not currently change to reflect lockdown status. The T58W's XML Browser key type (17) does not support persistent LED color changes via Push XML or Execute commands — LED commands are transient and immediately overridden by the phone's key type management.
SSM Parameters
| Parameter | Type | Description |
|---|---|---|

CI/CD
Pushes to main trigger an AWS CodePipeline (V2) that runs cdk deploy via CodeBuild.
| Resource | Name |
|---|---|
| Pipeline | seahaven-door-unlock-api-pipeline |
| CodeBuild project | seahaven-door-unlock-api-build |
| Artifact bucket | seahaven-door-unlock-api-pipeline-artifacts |
The CodeBuild role assumes CDK bootstrap roles for deployment — no separate CloudFormation stage.
Manual Deployment
npm install
npx cdk deploy
Phone Configuration
Configure DSS keys on the Yealink T54W/T58W (via phone web UI or 3CX):
-
Key 2 — Unlock Door
- Type: URL
- Value:
https://doorunlock.seahaven.com/unlock?token=<auth-token>
-
Keys 3-4 — Lockdown Toggle
- Type: XML Browser (17)
- Value:
https://doorunlock.seahaven.com/lockdown?token=<auth-token>&profile=bohemia|ronkonkoma
3CX Provisioning Templates
Custom 3CX templates are included with door unlock and lockdown URLs hardcoded.
