# Sea Haven Door Unlock API
|
|
|
|
AWS Lambda middleware that allows a Yealink T58A desk phone to unlock the front door controlled by LenelS2 Elements. Press a DSS key on the phone, and the door unlocks.
|
|
|
|
```
|
|
Yealink T58A → HTTPS GET → API Gateway → Lambda → LenelS2 Elements API → Door Unlocks
|
|
```
|
|
|
|
## Architecture
|
|
|
|
- **API Gateway (HTTP API)** — single `GET /unlock` endpoint with throttling (5 burst / 2 sustained req/sec)
|
|
- **Lambda (Node.js 20.x)** — validates a shared auth token, calls the Elements `TemporaryUnlock` command
|
|
- **SSM Parameter Store** — stores the Elements API key, auth token, and door device ID
|
|
- **Custom Domain** — `doorunlock.seahaven.com` via Route 53 + ACM wildcard cert
|
|
|
|
## SSM Parameters
|

|
| `/seahaven/door-unlock/auth-token` | SecureString | Shared secret embedded in the Yealink DSS key URL |
|
|
| `/seahaven/door-unlock/door-id` | String | Elements device ID for the front door reader |

|
