Some of our nixie clocks can be controlled programmatically over REST API. This feature offers possibilities to display custom numbers or control brightness over the clock as you wish. Individual API calls are sent to our cloud server that communicates with the clock. The clock must be connected to the internet to make the API calls work properly.

Authentication

You will need to know or get the following variables for communication with our clocks:

  • EMAIL, PASSWORD – use the same credentials as for our web or mobile app
  • ACCESS_TOKEN – you will get one after successful login. Every other API call must be authorized using this token. Session token has an expiration time of 1 year.
  • CLOCK_ID – See the table below in section Clock IDs.
  • API URL – https://api.daliborfarny.com/

Clock IDs

Each clock model has a certain product ID, Zen clocks 2, 4-tube Puri 6, etc. This is not a serial number that is unique for each clock.

Clock Name Clock ID
Zen Nixie Clock 2
Puri Nixie Clock (4-tube) 6
Puri Nixie Clock (6-tube) 15
Nixie Machine II 3
Nixie Machine III 9
NX.2 4

Obtaining the ACCESS_TOKEN

Use your EMAIL and PASSWORD to obtain ACCESS_TOKEN. Replace EMAIL and PASSWORD with the actual credentials you are using on https://user.daliborfarny.com/ or in the mobile app.

API call specification:

  • Request type – POST
  • Endpoint URL/oauth/token
  • Request body – client_id=3rdparty&client_secret=ws7TQHXp5W6444t4&grant_type=password&username=EMAIL&password=PASSWORD

Example API call using curl:

$ curl -X POST https://api.daliborfarny.com/oauth/token -d "client_id=3rdparty&client_secret=ws7TQHXp5W6444t4&grant_type=password&username=EMAIL&password=PASSWORD"

The server responds with a JSON containing the access_token:

{
"ok":true,
"status":200,
"data":{
        "access_token":"62dd89362a635ff8692a590456e8a8118e61d9902",
        "expires_in":31536000,
        "token_type":"Bearer",
        "scope":null,
        "refresh_token":"ef687d958f83ad13dff915d89f54ab2d8322193a"
        }
}

You can test this step manually from the command line:

Getting a list of your clocks

The next step is to get a list of clocks that are paired to your account. The pairing is done automatically during the process of connecting the clock to the internet. Replace the ACCESS_TOKEN with the access token you received in the previous step.

API call specification:

  • Request type – GET
  • Endpoint URL/v1/devices?client_id=3rdparty&access_token=ACCESS_TOKEN&client_secret=ws7TQHXp5W6444t4

Example API call using curl:

$ curl -X GET "https://api.daliborfarny.com/v1/devices?client_id=3rdparty&access_token=62dd89362a635ff8692a590456e8a8118e61d9902&client_secret=ws7TQHXp5W6444t4"

The JSON response returned by the cloud server:

{
   "ok":true,
   "status":200,
   "data":[
      {
         "id":"2d001c110c47363463353230",
         "name":"Puri Nixie Clock #51",
         "product_name":"Puri-4 Nixie Clock",
         "img_url":"https:\/\/www.daliborfarny.com\/wp-content\/uploads\/2018\/09\/LKJ4467_1024.jpg",
         "id_product":"6"
      },
      {
         "id":"320029000147373336323320",
         "name":"Puri-4 Nixie Clock #95",
         "product_name":"Puri-4 Nixie Clock",
         "img_url":"https:\/\/www.daliborfarny.com\/wp-content\/uploads\/2018\/09\/LKJ4467_1024.jpg",
         "id_product":"6"
      }
   ]
}

Checking online connection of the clock to the cloud

Now we need to test whether the clock is connected to the cloud and we can “talk” to it.

API call specification:

  • Request type – GET
  • Endpoint URL/v1/devices/CLOCK_ID/online?client_id=3rdparty&access_token=ACCESS_TOKEN&client_secret=ws7TQHXp5W6444t4

Example API call using curl:

$ curl -X GET "https://api.daliborfarny.com/v1/devices/320029000147373336323320/online?client_id=3rdparty&access_token=62dd89362a635ff8692a590456e8a8118e61d9902&client_secret=ws7TQHXp5W6444t4"

The JSON response returned by the cloud server:

{
   "ok":true,
   "status":200,
   "data":{
      "value":true
   }
}

Reading the configuration parameters

All the configuration parameters are stored in the clock itself, we can read them by sending API calls according to the specification below. The PARAMETER is to be replaced by the actual parameter name that we want to read from the clock.

API call specification:

  • Request type – GET
  • Endpoint URL/v1/devices/CLOCK_ID/PARAMETER?client_id=3rdparty&access_token=ACCESS_TOKEN&client_secret=ws7TQHXp5W6444t4

Example API call to retrieve the value of “transition” parameter using curl:

$ curl -X GET "https://api.daliborfarny.com/v1/devices/320029000147373336323320/transition?client_id=3rdparty&access_token=62dd89362a635ff8692a590456e8a8118e61d9902&client_secret=ws7TQHXp5W6444t4"

The JSON response returned by the cloud server, the parameter value in this example is “2”.

{
   "ok":true,
   "status":200,
   "data":{
      "value":2
   }
}

Sending the configuration parameters

All the configuration parameters are stored in the clock itself, to change the particular parameter, we need to do an API call as below. The PARAMETER is to be replaced by the actual parameter name that we want to read from the clock. The VALUE is the actual value we want to set the PARAMETER to.

API call specification:

  • Request type – POST
  • Endpoint URL/v1/devices/CLOCK_ID/PARAMETER
  • Request body – access_token=ACCESS_TOKEN&arg=VALUE&client_secret=ws7TQHXp5W6444t4&client_id=3rdparty

Example API call using curl – this way we can set parameter “transition” to value 3.

$ curl -X POST "https://api.daliborfarny.com/v1/devices/320029000147373336323320/transition" -d "access_token=62dd89362a635ff8692a590456e8a8118e61d9902&arg=3&client_id=3rdparty&client_secret=ws7TQHXp5W6444t4"

The JSON response returned by the cloud server:

{
   "ok":true,
   "status":200,
   "data":{
      "value":2
   }
}

Custom data

8 characters representing 6 tubes and 2 colon tubes (two tubes and one colon are not displayed on Puri-4).

Special characters:

  • “_” blanking the position (works both for colon and numerical tube)
  • “:” both dots activated, for colon tube only
  • “.” lower dot activated, for colon tube only
  • “;” upper dot activated, for colon tube only

String examples:

  • “12_34_56” displays 123456 on nixie tubes while blanking colon tubes
  • “_____.25” displays 25 on the right pair of tubes and a lower dot on the right colon tube
  • ;15;” blanks all tubes except the middle pair, both colons display upper dot

Custom data timeout

This parameter tells the clock after what time it must switch back to time mode (displaying time) after custom data were received. The actual period is calculated as a square of the value you send to give a better resolution. If you send the value “5”, the period of timeout will be 25 seconds (5 × 5 = 25).

Switch to time mode

Call this parameter to switch the clock to time mode (e.g. from custom data mode or from slot machine mode).

Slotmachine mode

1 = activate, 2 = deactivate

Homekit reset

Call this parameter to delete the current Homekit pairing and reset it to default.
