Any update on this?
Protocol document: https://coolkit-technologies.github.io/eWeLink-API/#/en/UIIDProtocol?id=uiid5-power-detection-single-channel-plug
The real-time acquisition of power, current, and voltage is achieved by issuing uiActive commands to activate the device every 60 seconds, so you need to establish a websocket connection to monitor the device status in real time and query it through the above protocol.
Document information on establishing a websocket connection: https://coolkit-technologies.github.io/eWeLink-API/#/en/APICenterV2?id=real-time-control-device
Only one latest historical record reported by the device can be obtained through the interface.
@nocmt thanks for the response. Your explanation help me understand what I am seeing and what I need to do.
@nocmt , is there a working sample code showing both onMessage and logging in with the appId and appSecret?
Using the code below, I am unclear how to subscribe to 'onMessage' or to fetch the power state. I have also noted that below the "wsClient.Connect.updateState('1001f7e71b', { switch: 'on',});" does not seem to turn the switch on.
// eWeLink WebSocket API
import eWeLink from "ewelink-api-next";
const wsClient = new eWeLink.Ws({
appId: 'pf2**********************j1w', // App ID, which needs to be configured in the eWeLink open platform
appSecret: 'c7h*****************x3a', // App Secret, which needs to be configured in the eWeLink open platform
region: "us"
});
let ws = await wsClient.Connect.create({
appId: wsClient?.appId || "",
at: wsClient.at,
region: "us",
userApiKey: wsClient.userApiKey
});
wsClient.Connect.updateState('1001f7e71b', {
switch: 'on',
});
wsClient.Connect.updateState('1001f7e71b', {
"uiActive": 60,
});
while (ws.readyState != 1) {
await new Promise(r => setTimeout(r, 1000));
}
while (ws.readyState ==1) {
await new Promise(r => setTimeout(r, 60000));
console.log(ws.readyState);
// get the power of the device here
// ?????
}
Any response?
Any response?

Here is an example of starting listening
Remember to add uiActive
Thanks @nocmt.
For others, here is the updated sample code:
import { wsClient, client } from './config.js';
import * as fs from "fs";
let region = "us";
let at = "";
const getUserApiKey = async ()=> {
if (fs.existsSync("token.json")) {
const tokenObj = JSON.parse(fs.readFileSync("token.json"));
at = client.at = tokenObj.data.accessToken;
region = client.region = tokenObj.region;
client.setUrl(region);
const response = await client.home.getFamily({});
return response.error === 0 ? response.data.familyList[0]?.apikey : null;
}else{
console.error("token.json not found");
process.exit(1);
}
}
function isJson(str) {
try {
JSON.parse(str);
} catch (e) {
return false;
}
return true;
}
// GET@/v2/family
wsClient.userApiKey = await getUserApiKey();
if (wsClient.userApiKey && region) {
await wsClient.Connect.create({
appId: wsClient?.appId || "",
at: at,
region: region,
userApiKey: wsClient.userApiKey
}, ()=>{
console.log("connected");
wsClient.Connect.updateState('10******1b', {
"uiActive": 60,
})
}, ()=>{
console.log("disconnected");
}, (_err)=>{
console.log("Error generated:", _err);
}, (_ws, _msg)=>{
const currentDate = new Date();
if (isJson(_msg.data)) {
let message = JSON.parse(_msg.data);
if (message.hasOwnProperty('params')){
message.params.date = currentDate;
console.log(message.params);
}
} else {
console.log(`${currentDate}: `, _msg.data);
}
});
}
After adding a token.json file and running node wssDemo.js I get the following output:
$ node wssDemo.js
connected
{
power: '0.00',
voltage: '122.76',
current: '0.00',
date: 2024-03-26T23:23:00.515Z
}
@ksaye I just want to say thank you for this code, it was really helpful! This works with Sonoff S60 also
I love the node package ‘ewelink-api-next@1.0.1’ and use it all the time to get the status of all my devices with the command ‘await client.device.getAllThings({})’.
I recently added a device ‘S31TPB(US)’ with the hope of reading the current, power and voltage.
Using the getAllThings({}), I see the device below, but the power, current and voltage do not change UNTIL I launch the EWELINK app on my phone.
How do I get the current power, current and voltage on devices?
