# Ism8 Binding
This binding can receive measurements from a 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 forwards those messages into the KNX bus system. If 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 such a way that the ISM8 connects to a partner and sends, from time to time, an update. The frequency depends on the change in values. This binding is listening to those messages. After the first connection, there is an active command sent to the ISM8 in order to receive all available data points. The manual for the ISM8 can be downloaded here: (https://oxomi.com/service/json/catalog/pdf?portal=2024876&user=&roles=&accessToken=&catalog=10572791 (opens new window))
Note that there are different firmware versions of the ISM8 module. Some data points are not available with older firmware versions.
# 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 full flexibility 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 a data point. Please take a look at the official manual from Wolf. Within this document, you'll find a table containing all supported data points. Depending on your heating system configuration, different data points are available. The ISM8 does currently support 4 different devices at the same moment of time (e.g., CHA, CGB-2, CWL Excellent, Solar, etc.).
Once you have an overview of your heating system, you can start to create the channels accordingly. Each channel should be created in the following way:
| Type | Name | Description | Configuration |
|---|---|---|---|
| Number:Temperature | DpId004 | "Kesseltemperatur" |
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 is available within the Wolf manual.
Depending on the firmware version of the ISM8 and the connected systems, the supported IDs differ.
- 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 data types of the ISM8 interface are fully supported. For the moment, the following data types are implemented:
| Channel type | Datapoint type | Item type | R/W | KNX-type's |
|---|---|---|---|---|
| switch-rw | Digital DataPoint | Switch | R/W | 1.001, 1.002, 1.003, 1.009 |
| switch-r | Digital Readonly DataPoint | Switch | R | 1.001, 1.002, 1.003, 1.009 |
| percentage-rw | Percentage DataPoint | Number:Dimensionless | R/W | 5.001 |
| percentage-r | Percentage Readonly DataPoint | Number:Dimensionless | R | 5.001 |
| number-r | Numeric Readonly DataPoint | Number:Dimensionless | R | 5.010, 7.001 |
| temperature-rw | Temperature DataPoint | Number:Temperature | R/W | 9.001,9.002 |
| temperature-r | Temperature Readonly DataPoint | Number:Temperature | R | 9.002,9.002 |
| pressure-r | Pressure Readonly DataPoint | Number:Pressure | R | 9.006 |
| flowrate-r | Flowrate Readonly DataPoint | Number:VolumetricFlowRate | R | 9.025, 13.002 |
| active-energy-r | Active Energy Readonly DataPoint | Number:Energy | R | 13.010, 13.013 |
| mode-rw | Mode DataPoint | Number:Dimensionless | R/W | 20.102, 20.103, 20.105 |
| mode-r | Mode Readonly DataPoint | Number:Dimensionless | R | 20.102, 20.103, 20.105 |
Date and Time types used by for CWL Excellent and CWL2 are currently not supported by the ISM8 add-on.
Attention: Due to a bug in the original implementation, the states for DPT 1.009 are inverted (i.e., 1 is mapped to OPEN instead of CLOSE).
A change would break all existing installations and is therefore not implemented.
