What is it?

This adapter provides an interface between the Synology Chat and ioBroker.
For this purpose, the standard integration features provided by Synology Chat and the corresponding REST API endpoints are used. Incoming and Outgoing integrations can be used to send messages to the Synology chat server or update a message object within your ioBroker instance to receive messages.


Manual

1. Installation

The adapter can be instantiated from the adapter section in your ioBroker installation. More information can be found in the official ioBroker documentation.

2. Configuration

2.1. Synology chat configuration

  • The Synology Chat offers the possibility to handle incoming and outgoing messages. In the following, both options will be examined in more detail.

  • To create messages via the Synology Chat interface, an integration must be created in Synology Chat: SynoChatChannel SynoChatIntegrations

    2.1.1. Incoming integration

    For the integration of an incoming message in the Synology chat, a token is needed, which can be taken from the URL generated during the creation. SynoChatIntegrationIncoming SynoChatIntegrationIncomingSettings

    2.1.2. Outgoing integration

    For the integration of an outgoing message in the Synology chat, a web hook URL needs to be provided. You will get this web hook URL from the instance objects after instantiating the synochat adapter. More details can be found in 3. Usage > 3.1 General SynoChatIntegrationIncoming SynoChatIntegrationIncomingSettings

NOTE: The channel type (incoming; outgoing) is specified from the perspective of the Synology chat. For example, 'Incoming' means that the messages will be sent to the Synology chat server.

For more details on how to handle integrations within Synology chat, please refer to Synology's official documentation HERE

2.2. ioBroker adapter instance configuration

  • The configuration of this adapter can be done in the instance settings.

    2.2.1. Main settings:

    IobrokerInstanceSettingsMainSettings

    • Synology URL/IP

      With this property a URL to your Synology-Chat app will be provided. Please note to use an absolute URL including http:// or https:// and do not provide an postfix like /. A specific port can be provided as usual behind the URL using :.

      Sample for valid values:

    • Validate SSL certificate

      It is of course always recommended to encrypt data transfers. Often, self-signed certificates are used for encrypted connections in home environments. In this case, it may be necessary to disable SSL certificate verification of an HTTP connection. Disable this property to turn off certificate validation.

    • Hostname / IP address of ioBroker instance

      This property allows you to specify the hostname or IP address at which your ioBroker instance is accessible via URL. This value is automatically set to the current IP address of the host operating system of your ioBroker installation after the initial adapter instantiation.

      In case of using ioBroker as a Docker instance, it may be necessary to change this value, e.g. if a reverse proxy or similar is used to reach your ioBroker instance.

      This value is used to generate the web hook URL for channels that receive messages from the Synology chat server.

    • Web instance for messages send from Synology chat to ioBroker adapter instance

      The synochat adapter is using a web adapter to make web hooks available. You need to select a specific instance of the web adapter to provide a dedicated web hook to the Synology chat integration.

    2.2.2. Channel management / configuration:

    IobrokerInstanceSettingsChannelConfiguration

    • Channel enabled

      This option can be used to disable the handling of incoming or outgoing messages.

      This can be useful if e.g. the user wants to disable the use of a channel only temporarily and wants to keep the settings like the access token or similar to prevent to collect them again.

    • Channel name

      This setting specifies the name of the channel from/to which messages are sent. This name is free to choose in case of channels of type Send data to Synology chat server - Incoming integration and is used for referencing.

      The channel name to be configured here should be identical to the channel name of the Synology chat.

      For channels of type Get data from Synology chat server - Outgoing integration the name must be identical to the channel name of the Synology chat channel in order to receive messages. The mapping of the channel names is case sensitive (upper and lower case must be taken into account).

    • Channel token

      This setting provides the access token to the Synology chat channel. Depending on the channel type, the creation of this varies. More details can be found in chapter Synology chat configuration.

      NOTE:
      Depending on the integration, when create the Synology chat integration, you will get a link similar to the following example:

        https://mychat.mydomain.tld/webapi/entry.cgi?api=SYNO.Chat.External&method=incoming&version=2&token=%22QF5DWyG7M47Ls3cv%22
      

      In this example, the token is included in the URL. Encoded control characters - %22 - are specified here at the beginning and end of the setting.
      These have to be removed!
      In this example the token to be entered would be QF5DWyG7M47Ls3cv.

    • Channel type

      NOTE:
      The channel type must be specified from the perspective of the Synology chat. For example, selecting 'Incoming' in the configuration means that the messages will be sent to the Synology chat.

      This setting specifies the type of Synology chat channel that will be used depending on the integration selected in Synology chat.

      • Send data to Synology chat server - Incoming integration
        This option enables the channel to send the new value of the ioBroker message object (see usage chapter) as soon as the object value changes.

      • Get data from Synology chat server - Outgoing integration
        This option enables the channel to receive messages from the Synology chat server and update the new value of the ioBroker message object (see usage chapter).

        Please note that when using this channel type, the channel name of the ioBroker adapter instance configuration must be identical to the channel name of the Synology chat channel in order to receive messages. The mapping of the channel names is case sensitive (upper and lower case must be taken into account).

        Note: Please make sure not to select the 'react on' options for outgoing channels

      If a channel should be configured in both, sending and receiving messages, simply add a second channel with the same name and select the other channel type.

    • Object value template

      If the value of a channel message object contains a JSON value, you can select a template that parses this object value into a human-readable value before sending it to the Synology chat channel.

      The related message template can be configured in the Message templates section.

    • React on Notification-Manager

      The synochat is able to receive messages from ioBroker Notification-Manager. This option allows you to choose whether the corresponding channel should react to messages from Notification Manager and forward them to Synology Chat accordingly.

      The related message template can be configured in the Message templates section.

    • React on all ioBroker messages

      Beside the messages from the ioBroker Notification-Manager synochat is able to receive also other messages from other adapters. This option allows you to choose whether the corresponding channel should react to messages from all other senders and forward them to Synology Chat accordingly.

      An adapter instance can receive messages. These messages consist of an object with several attributes that can be included as parameters in a message template. These parameters are replaced accordingly before the message is sent.

      The related message template can be configured in the Message templates section.

    • Validate SSL certificate - For non-text messages

      In case that for an incoming channel type a content other than a text, for example an image, is to be sent, this is specified from an HTTP source via a URL. If this content is provided with a self-signed certificate, the certificate check can be enabled or disabled with this setting. For details on sending non-text content, see chapter Synology chat configuration..

    2.2.3. Message templates:

    It is possible to define message templates that are processed before sending a message to Synology Chat Server. These templates can contain patterns that are replaced during the sending process.

    IobrokerInstanceSettingsChannelConfiguration

    Patterns must always start with ${ and end with }. e.g. ${foo}. While processing the message the pattern ${foo} will be replaces with the corresponding JSON value of the attribute foo.

    Sample:

    If a channel configured to send data to Synology Chat receives an object change to its message object, it may contain a JSON value like the following:

     {
         "sensor": {
             "id": "temp0815",
             "name": "Temperature - Living room",
             "type": "temperature",
             "location": "living room",
             "value": "23.4"
         }
     }

    You can access the inner attributes of this value by providing them in a path like ${sensor.value}.

    If you would like to send a text like

    The temperature in the living room changed to 23.4°C

    your message template would look like this:

    The ${type} in the ${location} changed to ${value}°C

    NOTE AND RESTRICTIONS:

    1. If you are trying to access an attribute with a key containing dots (.) you have to escape them with the chars /-!

      e.g. if your message object value look like this:

      {
          "category": {
              "instances": {
                  "system.adapter.notification-manager.0": {
                      "notification": "Test notification",
                  }
              }
          }
      }

      and you want to access the attribute notification, your pattern will be ${category.instances.system/-adapter/-notification-manager/-0.notification}

    2. It is not possible to access specific items in arrays.

      e.g. if your message object value look like this:

      {
          "messages": [
              {
              "text": "Lorem"
              },
              {
              "text": "Ipsum"
              }
          ]
      }

      you cannot access the text attribute in the message object. In this case you need to prepare the object value outside this adapter before passing it to the synochat channel message object.

    • Template for sending messages received via ioBroker Notification-Manager

      This template will define the message of messages received from the Notification-Manager. As parameters in your template you can use attribute names of the iobroker.Message object and the embedded Notification-Manager message object.

      The internal received object is of type iobroker.Message:

       /** A message being passed between adapter instances */
       interface Message {
           /** The command to be executed */
           command: string;
           /** The message payload */
           message: MessagePayload;
           /** The source of this message */
           from: string;
           /** ID of this message */
           _id: number;
           /** Callback information. This is set when the source expects a response */
           callback: MessageCallbackInfo;
       }

      As per description, the Notification-Manager will provide its own message object embedded in the message attribute as part of the iobroker.Message.

      You can access these data via the message attribute by using the pattern ${message.NOTIFICATION_MANAGER_ATTRIBUTES}.

      Available patterns:

      • ${command} - Pattern related to the iobroker.Message object
      • ${message} - Pattern related to the iobroker.Message object
      • ${from} - Pattern related to the iobroker.Message object
      • ${_id} - Pattern related to the iobroker.Message object
      • ${instances} - Pattern will be replaced with a list of instances related to the received notification of the Notification-Manager

      More information about the structure of the Notification-Manager message object can be found in the README.

      Note: Please make sure not to select the 'react on' options for outgoing channels

    • Template for sending messages of all other received messages

      The same iobroker.Message object as described above is used for sending all kinds of messages to an adapter instance.

       /** A message being passed between adapter instances */
       interface Message {
           /** The command to be executed */
           command: string;
           /** The message payload */
           message: MessagePayload;
           /** The source of this message */
           from: string;
           /** ID of this message */
           _id: number;
           /** Callback information. This is set when the source expects a response */
           callback: MessageCallbackInfo;
       }

      From this object itself it is possible to use the following patterns to access the values of the related attributes.

      Available patterns:

      • ${command} - Pattern related to the iobroker.Message object
      • ${message} - Pattern related to the iobroker.Message object
      • ${from} - Pattern related to the iobroker.Message object
      • ${_id} - Pattern related to the iobroker.Message object

      The pattern ${message} is always the one what will contain the information from the corresponding sender. If the message is only containing a String you only need to provide the pattern ${message}. Is it providing a JSON value you can also access the inner attributes by providing the path to the value like ${message.foo.bar}.

      Note: Please make sure not to select the 'react on' options for outgoing channels

    • Template 1-10 - Template to be applied on a specific channel

      You can also provide a JSON value to a message object of a specific channel. In this case, you can define up to ten user-specific templates, that can be applied before sending the message to the Synology Chat server.

      The JSON attributes can be accessed by providing the path to the value as a pattern like ${foo.bar}.

      A template can be associated to a channel in the Channel configuration.

      Available patterns:

      The available patterns are related to the customer JSON value that will be provided to the channel message object.

    2.2.4. Help:

    • This tab usually redirects to the official GitHub page of this project, where detailed help and usage instructions are given.
    • If there are any open questions, suggestions for changes, unwanted behavior or bugs, please create a GitHub issue to ensure the quality of this project.

2.3. Configuration of the web instance

For receiving messages from the Synology chat server an outgoing integration is needed to be configured - See Outgoing integration.

This requires an instance of the web adapter to be running and configures in the synochat adapter instance configured.

If the used web instance is configured to use a secure connection over HTTPS, ensure that you provide a valid certificate or import your own certificate to the trusted certificates in your Synology.
Otherwise, no messages are sent from the Synology chat server to your ioBroker adapter instance. The communication will not be established and unfortunately there will be no direct indication to the user on both sites that the message was rejected due to an invalid certificate.

3. Usage

3.1 General

  • After configuring the adapter instance, a folder with the channel name is created for each configured channel in the objects of the respective adapter instance. IobrokerObjectOverview

  • In this folder a message object of the respective channel can be found, which represents the sent or received message.

    NOTE:
    When sending a message or when the message object is changed by the user, make sure that the Ack flag is not set. The Ack flag will be set by the adapter after confirmation of successful receipt of the message by the Synology chat server.
    If the Ack flag is set by the user while changing the message value in the ioBroker object view, the message will not be processed!*

    IobrokerObjectSetMessage

  • When the message object is changed and the channel type is set to Send data to Synology chat server, this message is passed to the Synology chat. SynoChatChannelIncomingMessage

  • To receive messages from Synology Chat Server and for the message object to be updated accordingly, make sure that the configured Trigger word (see Synology chat configuration) is in the message without punctuation. So it must stand alone.

    Example:
    If the Trigger word would be Alarm, the message in Synology chat should look like this:
    An alarm was triggered in the hallway.

    Please note that the Trigger word is case sensitive (upper and lower case must be taken into account).

  • The web hook URL / address will be provided as an object value in the info folder of the adapter instance and is valid for all channels withing one adapter instance. IobrokerObjectWebHook

3.2 Message content type

Besides sending plain text messages, other content types such as images can also be sent to an incoming channel.
To realize this, the content must be available as a web resource. To send an image, just set the URL as the value of the the message object of the Syno-Chat adapter instance mentioned in 3. Usage > 3.1 General.

Example of a use case of a surveillance camera:
Many surveillance cameras provide a stream or interface to retrieve an image that is updated at a specified time interval or when motion is detected.
This URL provides image that needs to be set as the value of the the message object.

3.3 Debugging in case of issues

To get more detailed information about the adapter behaviors in case of issues, you can increase the log level of the synochat adapter instance to debug.

Since this adapter is using a web adapter instance to provide web hooks to the Synology chat server, the configured web instance is executing some functions. In order to get more detailed information in case of receiving message issues you need to increase the log level of the configured web instance as well to debug. Log messages related to the synochat adapter can be identified by the log message prefix synochat.<INSTANCE_NUMBER>.
