Analysis
Relay Switch 2PM doesn't work via API properly: only a few commands described in API-Documentation are working:
'setPosition': (value) => ({ command: 'setPosition', parameter: 0,ff,${value} }),
'setBlindPosition': (value) => ({ command: 'setPosition', parameter: String(value), commandType: 'command' }),
So one can substitute open and close with ({command: 'setPosition', parameter: '0'}) - or '100' responsively.
For 'pause'/'stop' are - probably - commands ({command: 'turnOff' parameter: '1' }) - or '2' needed:
With these - in API named - commands: 'turnOn'/'turnOff' none of the relays in the device switch on/off (same environment). Despite of this the response is {"statusCode":100,"body":{},"message":"success"}.
Javascript for testing (Sample in above API is buggy: body is missing):
const crypto = require('crypto');
const https = require('https');
const { v4: uuidv4 } = require('uuid');
const nonce = uuidv4();
const token = "c734e6c01b6361cd3...";
const secret = "26392f2cc99...";
const t = Date.now();
const nonce = "requestID";
const data = token + t + nonce;
const sign = crypto
.createHmac('sha256', secret)
.update(data)
.digest('base64');
console.log(sign);
const body = JSON.stringify({
"command": "turnOn",
"parameter": "1", // or "2"
"commandType": "command"
});
const deviceId = "9888E0D63736";
const options = {
hostname: 'api.switch-bot.com',
port: 443,
path: `/v1.1/devices/${deviceId}/commands`,
method: 'POST',
body: body, // missing in API sample
headers: {
"Authorization": token,
"sign": sign,
"nonce": nonce,
"t": t,
'Content-Type': 'application/json',
'Content-Length': body.length,
},
};
const req = https.request(options, res => {
console.log(`statusCode: ${res.statusCode}`);
let responseBody = '';
res.on('data', d => {
// process.stdout.write(d);
responseBody += d;
});
res.on('end', () => {
console.log(`API Antwort: ${responseBody}`);
});
});
req.on('error', error => {
console.error(error);
});
req.write(body);
req.end();
Expected Behavior
Relay Switch 2PM works as in API described
Steps To Reproduce
Run above script on another implementation using API. Send turnOn/turnOff command as shown above. Check relays - no reaction.
