What's the rf_address

[RalphPungaKronbergs]

Hi,

on my way to create a homebridge package for Max! Cube I would like to use maxcube, but I can't figure where I get the 'rf_address' for each device of my Max! setup...

Would appreciate any help!

Cheers
Punga

If you run following code (change ip according to your setup), you should get a list of all connected devices, including their rf-address:

var MaxCube = require('maxcube');
var myMaxCube = new MaxCube('192.168.1.123', 62910);

myMaxCube.on('connected', function () {
  console.log('Connected');

  myMaxCube.getDeviceStatus().then(function (payload) {
    console.log(payload);
    myMaxCube.close();
  });
});

myMaxCube.on('closed', function () {
  console.log('Connection closed');
});

Output:

Connected
[ { rf_address: '0aa123',
    initialized: true,
    fromCmd: false,
    error: false,
    valid: true,
    mode: 'MANUAL',
    dst_active: true,
    gateway_known: true,
    panel_locked: false,
    link_error: false,
    battery_low: false,
    valve: 0,
    setpoint: 6,
    temp: 0 },
  { rf_address: '0bb123',
    initialized: true,
    fromCmd: false,
    error: false,
    valid: true,
    mode: 'MANUAL',
    dst_active: true,
    gateway_known: true,
    panel_locked: true,
    link_error: false,
    battery_low: false,
    valve: 100,
    setpoint: 30.5,
    temp: 0 } ]
Connection closed

Thanks for the reply!

Using your script unfortunately there is not connected state rising, although I use the correct IP and Port - both are working with a PHP script that can read MAX! configuration and when I telnet into the MAX! Cube.

Any idea?

[ivesdebruycker]

There can only be one connection to the MAX! Cube at the same time.
If you're connected to the cube via the MAX! application or any other way (e.g. a PHP script), you should exit those and try again.

If there's already a connection, you'll get a timeout:

{ [Error: connect ETIMEDOUT 192.168.1.123:62910]
  code: 'ETIMEDOUT',
  errno: 'ETIMEDOUT',
  syscall: 'connect',
  address: '192.168.1.123',
  port: 62910 }
events.js:146
      throw err;

[RalphPungaKronbergs]

The MAX! Application is not running currently.

Got your code running (placed it somewhere else in the homebridge code), but the result is:

/Users/punga/node_modules/homebridge-maxcube/node_modules/maxcube/maxcube-commandparser.js:204
    default: deviceType = EQ3MAX_DEV_TYPE_UNKOWN; break;
                          ^

Does this help to identify the issue?

Oh, it seems like there is a typo in "EQ3MAX_DEV_TYPE_UNKNOWN" on line 204.
After fixing, your code works! Great!

Thanks for your help!

[ivesdebruycker]

Yup, that's a bug, fixed in 67c4694, thanks.
Seems you have an unrecognized device, mind telling what it is?

[RalphPungaKronbergs]

Sure, it's a MAX! Cube but sold from ELV (www.elv.de), not EQ-3 (although it's absolutely the same). Does this help or do you need some other information?

[ivesdebruycker]

If you could give me the submessage length of this device, that would be helpfull.
By temporary changing line 204 in maxcube-commandparser.js to this, it wil print out the length:
default: deviceType = EQ3MAX_DEV_TYPE_UNKNOWN; console.log('Submessage Length: ' + payload[0]); break;

[RalphPungaKronbergs]

No problem, the output is: 6

Unfortunately I still get an error if trying to set the temperature for an existing device:

maxcube.js:134
  var command = MaxCubeCommandFactory.generateSetTemperatureCommand (rf_address, this.deviceCache[rf_address].room_id, 'MANUAL', degrees);
                                                                                                             ^
TypeError: Cannot read property 'room_id' of undefined

My code is:

          var MaxCubeApi = require('maxcube');   
          deviceId = '12afdd';
           temp = 19;
           var myMaxCube = new MaxCubeApi('192.168.1.31', 62910);

           myMaxCube.on('connected', function () {
          myMaxCube.setTemperature(deviceId, temp).then(function (success) {
                 if (success) {
                    console.log('Temperature set');
                 } else {
                    console.log('Error setting temperature');
                 }
                 myMaxCube.close();
              })
           });         

Do I miss something, like building the device cache first?

BTW: Is it possible to set temp to an wall mounted thermostat? Because the device list shows only
{ rf_address: '0ee83c' }
for a wallthermostat, while the bounded thermostat itself has a more detailed result:

{ rf_address: '12afdd',
    initialized: true,
    fromCmd: false,
    error: false,
    valid: true,
    mode: 'AUTO',
    dst_active: true,
    gateway_known: true,
    panel_locked: false,
    link_error: false,
    battery_low: false,
    valve: 100,
    setpoint: 22.5,
    temp: 0 }

Thanks
Ralph

Error TypeError: Cannot read property 'room_id' of undefined should be fixed, see #12.

I don't own a wall mounted thermostat, but that should be working after ad94108, see #15.
