# Ism8 Binding
This binding can receive values of the Wolf heating system.
The ISM8 card can be placed into the Wolf heating system. The card is usually used in combination with an object server, where the object server does forward those messages into the KNX bus system. In case there is no need to handle the heating system values directly in the KNX system you can use this binding to monitor and control your heating system without the need to buy an object server. The system works in a way that the ISM8 connects to a partner and sends from time to time an update. The frequency depends on the change of the values. This binding is listening to those messages. After the first connection there is an active command send to the ISM8 in order to receive all available data points. The manual of the ISM8 can be downloaded from the supplier (https://www.wolf.eu/fileadmin/Wolf_Profi/Downloads/Montage-Bedienungsanleitungen/Regelungen/Zubehoer/3064356_201611_ISM8i_Montage-u.Bedienungsanleitung.pdf (opens new window))
# Supported Things
This binding does only support one Thing - the Ism8-Device.
# Discovery
Auto-discovery is not supported.
# Thing Configuration
The intention was to have a generic ISM8 binding in order to offer the full flexibilty for the different heating systems.
For this reason you need to create a Thing configuration, where basically only the port is required next to the channel configuration.
(Thing ism8:device:heater "Wolf Heizung" [portNumber=12004])
# Channels
You can use any channel supported by the ISM8 as data point. Please have a look at the official manual from Wolf. Within this document you'll find a table containing all supported data points. The available data points are depending on your heating system configuration. The ISM8 does currently support 4 different devices at the same moment of time (e.g. CGB-2, CWL Excellent, Solar, ...).
Once you have an overview of your heating system set you can start to create the channels accordingly. Each channel should be created in the following way:
| Type | Name | Description | Configuration |
|---|---|---|---|
| Number | DpId004 | "Kesseltemperatur" | id, type, write |
Type:
- Switch use for boolean values
- Number use for any number
- Other types may work as well.
Name:
- Put here any name you'd like. This name is used for creating the binding.
Description:
- Put here any description you'd like or the description for the data point ID from the Wolf manual.
Configuration:
- id=1 - Please enter here the ID of the data point you'd like to map to this channel. A list of the available IDs are available within the Wolf manual. The supported IDs are depending on the firmware version of the ISM8 and the connected systems.
- type="1.001" - Please enter here the knx type of the data point. You can find the data type in the Wolf ISM8 document as well.
- write=true - This parameter defines if the channel is bidirectional, but the parameter is optional and by default false.
Note: Not all available types of the ISM8 interface are fully supported, but this can be extended. For the moment the following data types are implemented:
- DPT-Bool:
1.001,1.002,1.003,1.009 - DPT-Scaling:
5.001 - DPT-Value:
9.001,9.002,9.006 - DPT-FlowRate:
13.002 - DPT-Mode:
20.102,20.103,20.105
