This Enapter Device Blueprint integrates Sonoff Dual R3 one channel relay via eWelink REST API Server. The Blueprint is running on Enapter Virtual UCM. This Blueprint allow to control both relays as well as monitor voltage, current and power.

Requirements

eWelink account

You require to have email and password used for login as well as region.

The eWelink account can be created in the eWelink Mobile App.
Sonoff Device ID You can find it in the eWelink app:
1. Tap on Device.
2. Click ... in top right corner.
3. Scroll down to Device ID. Write it down for future use.
Latest version of Enapter Gateway Software

Enapter Gateway Software must support Virtual UCM and Docker containers runtime.

Running eWelink REST API Server

This Blueprint is using eWelink REST API Server. For more details visit it's page at GitHub - https://github.com/DoganM95/Ewelink-Rest-Api-Server and Docker Hub - https://hub.docker.com/r/doganm95/ewelink-rest-api-server

At the moment of writing the instruction the original eWelink REST API server has no suppot for several channel devices. The patch is available at this repository https://github.com/nkrasko/Ewelink-Rest-Api-Server.

The REST API is intermediate service from one sides connects to eWelink client API the same was as your mobile application and on the other side provide HTTP endpoint where you can get data of your devices in JSON format or execute commands for switches.

The beauty of this solution is possibility to use Enapter Energy Management toolkit and exisitng eWelink service.

In this example we will bild own container.

Clone repository

git clone https://github.com/nkrasko/Ewelink-Rest-Api-Server
cd Ewelink-Rest-Api-Server

Build container
```
docker build -t nkrasko/ewelink-rest-api-server -f ./docker/Dockerfile .
```
In case if you plan to run the docker container on Gateway (Option 2 below) you need to keep in mind that Enapter Gateway software is x86 based. This is important to know when you are building your docker container on other architecture, for example, Appe M1 (ARM) CPU.

If that is the case, build docker container the following way
```
docker build --platform=linux/amd64 -t nkrasko/ewelink-rest-api-server -f ./docker/Dockerfile .
```
Run docker container
- Option 1. Run docker container on general server.
```
docker run -d --restart unless-stopped \
    -p LOCAL_TCP_PORT:3000 \
    -e 'EWELINK_USERNAME=EMAIL' \
    -e 'EWELINK_PASSWORD=PASSWORD' \
    -e 'EWELINK_REGION=REGION' \
    -e 'SERVER_MODE=dev' \
    nkrasko/ewelink-rest-api-server
```
  Put the correct values for:
  - EMAIL - your eWelink email, for example, test@test.com
  - PASSWORD - your eWelink password
  - REGION - your eWelink Region:
  - Mainland China: CN
  - Asia: AS
  - Americas: US
  - Europe: EU
  - LOCAL_TCP_PORT: any free TCP port on which HTTP server will be listening. This port will be needed for Virtual UCM configurattion in next steps. For example, 8081.
  Check docker container is running and healthy by running command:
```
docker ps
```
  You should see something like:
```
CONTAINER ID   IMAGE                              COMMAND                  CREATED          STATUS          PORTS                    NAMES
6261c5dd833f   nkrasko/ewelink-rest-api-server   "docker-entrypoint.s…"   33 minutes ago   Up 33 minutes   0.0.0.0:8081->3000/tcp   hungry_lewin
```
In above example, the docker container is running on TCP port 8081.
- Option 2. Run docker container with docker-compose on Enapter Gateway 2.1.
  
  This option is helpful to minimize number of hardware used for running different custom services. Docker subsystem is running in stateless mode so every time container starts it is either requested from registry, built or taken from images cache. This example will explain how to put image to cache and write correct docker-compose file.
  
  Before continue ensure you are running Gateway 2.1.
  
  Export docker image from machine you've built it with docker build command.
```
docker save nkrasko/ewelink-rest-api-server > nkrasko_ewelink-rest-api-server.tar
```
  Copy docker image to temporary directory on your gateway with scp.
```
scp nkrasko_ewelink-rest-api-server.tar enapter@enapter-gateway.local:/tmp
```
  enapter-gateway.local should be resolvable with mDNS in your LAN. If not, use IP address of your gateway. As password use the password you set during initial Gateway configuration.
  
  Move image to docker images cache.
  
  ssh to gateway with ssh enapter@enapter-gateway.local command. Run bash command to switch to the shell.
```
[enapter] $ bash
enapter@gateway:~$
```
  become root with sudo su - command. whoami command is helpful to ensure your are root.
```
enapter@gateway:~$ sudo su -
root@gateway:~$
```
  move image to docker images cache
```
root@gateway:~$ mv /tmp/nkrasko_ewelink-rest-api-server.tar /user/etc/docker-compose/images/
```
  Edit docker compose configuration
  
  you can use vim or nano text editors.
```
root@gateway:~$ vim /user/etc/docker-compose/docker-compose.yml
```
  Put the following content into the file:
```
version: "3"
services:
    nkrasko-ewelink-api:
        image: localhost/nkrasko/ewelink-rest-api-server:latest
        ports:
            - '0.0.0.0:LOCAL_TCP_PORT:3000'
        environment:
            - 'EWELINK_USERNAME=EMAIL'
            - 'EWELINK_PASSWORD=PASSWORD'
            - 'EWELINK_REGION=EU'
            - 'SERVER_MODE=dev'
```
  Ensure you have right indentation and put right values for:
  - EMAIL - your eWelink email, for example, test@test.com
  - PASSWORD - your eWelink password
  - REGION - your eWelink Region:
    - Mainland China: CN
    - Asia: AS
    - Americas: US
    - Europe: EU
  - LOCAL_TCP_PORT: any free TCP port on which HTTP server will be listening. This port will be needed for Virtual UCM configurattion in next steps. For example, 9292.
  Start your configuration
```
root@gateway:~$ systemctl restart enapter-docker-compose
```
  The start can take some time. Be patient.
  
  Ensure your container is running
```
root@gateway:~$ docker-compose -f /user/etc/docker-compose/docker-compose.yml ps
                Name                              Command               State           Ports
------------------------------------------------------------------------------------------------------
docker-compose_nkrasko-ewelink-api_1   docker-entrypoint.sh node  ...   Up ()   0.0.0.0:9292->3000/tcp
root@gateway:~$
```
Check your API provides valid response with CURL from host where docker container runs:
```
curl http://127.0.0.1:8081
```
You should get valid JSON as response.

If everything is fine you are ready to connect your device to Enapter Cloud!

Connect to Enapter

Sign up to the Enapter Cloud using the Web or mobile app (iOS, Android).
Use the Enapter Gateway to run the Virtual UCM. If you are running eWelink REST API server on diiferent computer, ensure it is available from the Enapter Gateway.
Create the Enapter Virtual UCM.
Upload thie Blueprint using Enapter Marketplace on your mobile device. Advanced users can upload using Web IDE or CLI by following Developer Documentation.
As soon as Blueprint will start the Module Not Configured event will be triggered.
Navigate to Settings ().
Click Commands.
In the Settings section of the Commands screen click on Main Configuration command in the Enapter mobile or Web app to set main settings for your Virtual UCM:

You need to set the following parameters you got during previous steps:
- IP Address of eWelink REST API server
- IP Port
- Device ID
Press Run button

The status data should be available on your Sonoff Dual R3 dashboard as well as you can control your relay manually or automatic way with Enapter Rules Engine
