Ewelink REST API Server

A Node.js server application that processes HTTP requests and forwards commands to eWeLink servers for device operations like turn on/off or toggling. This server utilizes the eWeLink API.

Docker

docker run \
  -p <port>:3000 \
  -e "EWELINK_USERNAME=<your_username>" \
  -e "EWELINK_PASSWORD=<your_password>"  \
  -e "EWELINK_REGION=<your_region>" \
  -e "HASHING_ALGORITHM=<your_preferred_algorithm>" \
  -e "SERVER_MODE=dev" \
  -v "<your_local_pem_certs_folder>:/usr/src/app/volume/ssl/" \
  doganm95/ewelink-rest-api-server

Arguments

-e EWELINK_USERNAME - Your Ewelink Username, usually an email address
-e EWELINK_PASSWORD - Your Ewelink password
-e EWELINK_REGION - Your region, e.g. eu, us
-e PASSWORD_HASHING_ALGORITHM - supported:
RSA-MD4, RSA-MD5, RSA-MDC2, RSA-RIPEMD160, RSA-SHA1, RSA-SHA1-2, RSA-SHA224, RSA-SHA256, RSA-SHA3-224, RSA-SHA3-256, RSA-SHA3-384, RSA-SHA3-512, RSA-SHA384, RSA-SHA512, RSA-SHA512/224, RSA-SHA512/256, RSA-SM3, blake2b512, blake2s256, id-rsassa-pkcs1-v1_5-with-sha3-224, id-rsassa-pkcs1-v1_5-with-sha3-256, id-rsassa-pkcs1-v1_5-with-sha3-384, id-rsassa-pkcs1-v1_5-with-sha3-512, md4, md4WithRSAEncryption, md5, md5-sha1, md5WithRSAEncryption, mdc2, mdc2WithRSA, ripemd, ripemd160, ripemd160WithRSA, rmd160, sha1, sha1WithRSAEncryption, sha224, sha224WithRSAEncryption, sha256, sha256WithRSAEncryption, sha3-224, sha3-256, sha3-384, sha3-512, sha384, sha384WithRSAEncryption, sha512, sha512-224, sha512-224WithRSAEncryption, sha512-256, sha512-256WithRSAEncryption, sha512WithRSAEncryption, shake128, shake256, sm3, sm3WithRSAEncryption, ssl3-md5, ssl3-sha1, whirlpool.
Default, if omitted: sha3-512
-e SERVER_MODE can be prod or dev. For initial container setup & testing, try dev. If everything works, you can switch to -e "SERVER_MODE=prod", to turn off console logs
-p <port_to_use>:3000
-v <local_cert_folder>:/usr/src/app/volume/ssl/ - can contain the cert.pem and privkey.pem as files. If omitted, a non-ssl-encrypted http server will start

Example

docker run \  
  -p 8080:3000 \  
  -e "EWELINK_USERNAME=someone@gmail.com" \  
  -e "EWELINK_PASSWORD=passW"  \  
  -e "EWELINK_REGION=eu" \  
  -e "PASSWORD_HASHING_ALGORITHM=sha512" \  
  -e "SERVER_MODE=prod" \  
  -v "C:\Users\Dogan\OneDrive\Desktop\certs_tmp\:/usr/src/app/volume/ssl/" \  
  doganm95/ewelink-rest-api-server

Usage

Authorization

If SSL encryption is enabled (using privkey.pem and cert.pem files), each request must include an Authorization header with a Bearer Token. This token is your eWeLink password hashed using your chosen algorithm (default: sha3-512). In dev mode, the container logs the hashed password for copying.

API Endpoints

Fetch Devices List

Method: GET
Description: Retrieve a list of all registered devices along with their details.

Control a Device

Method: POST
Description: Control a device using its name or ID.
Body:
```
{  
  "devicenameincludes": ["desk", "light"],  
  "deviceid": "100012f3f4",
  "params": {
      "switch": "on",
      "outlet": 2
  }
}
```
- devicenameincludes: An array of keywords contained in the device name. The most relevant device is controlled based on these keywords.
- deviceid: Direct device ID reference (prioritized over devicenameincludes).
- switch: Device action - valid values are on, off, or toggle.
- outlet: Optional for multi-relay devices (starts from 1).
