Bosch Light/shutter control unit II

[sahnetorti]

Is there already an existing issue for this?

• [X] I have searched the existing issues and there is none for my device

Product name

Light/shutter control unit II

Manufacturer

Bosch

Model identifier

RBSH-MMS-ZB-EU

This device is a bit special as it has a "split personality": it can function as 2x switch (i.e. for controlling an on/off light) OR as a window covering device. For the latter it must be configured, which can be done using the Bosch Gateway & proprietary app but not through deconz (yet?)

The magic seems to be in the cluster #FCA0, where some attributes must be set accordingly. Unfortunately these cluster attributes are not available in deconz. A reference to these attributes can be found in a discussion for ZHA here

BTW I was able to pair this device through the "pair with install code" method in the REST API.

To add the feature in deconz, edit the general.xml file and for

service: zha_toolkit.attr_write
data:
  ieee: ...
  manf: 0x1209
  endpoint: 1
  cluster: 0xfca0
  attribute: 0x0000
  attr_type: 0x30
  attr_val: 0x01

The result will be

   <cluster id="0xfca0" name="Bosch specific" mfcode="0x1209">
        <description>Bosch Specific cluster.</description>
        <server>
        <attribute id="0x0000" type="enum8" name="shutter mode" access="rw" required="o" mfcode="0x1209">
            <value name="xxxx" value="0x00"></value>
            <value name="yyyyy" value="0x01"></value>
        </attribute>
        <attribute id="0x0002" type="u32" name="calibration closing time" access="rw" required="o" mfcode="0x1209"></attribute>
        </server>
        <client>
        </client>
    </cluster>

Need to restart deconz after changes.

So you miss feature, but the device is correclty reconized by defaut ? Or you need a DDF too ?

Hi smanar,

thanks for providing the relevant XML snippets. I added this to the general.xml:

    <cluster id="0xfca0" name="Bosch specific" mfcode="0x1209">
      <description>Bosch Specific cluster.</description>
      <server>
        <attribute id="0x0000" type="enum8" name="shutter mode" access="rw" required="o" mfcode="0x1209">
          <value name="Switch mode" value="0x00"></value>
          <value name="Rolershutter mode" value="0x01"></value>
        </attribute>
        <attribute id="0x0002" type="u32" name="calibration closing time" access="rw" required="o" mfcode="0x1209">
        </attribute>
      </server>
      <client>
      </client>
    </cluster>

which made the shutter work. I am not sure with the names for the modes&values, though, it might be that this is not accurate. I set the device to "rolershutter mode" / 0x01 and after that I could control the shutter (up/down/stop).

Additionjally I had to set the "calibration closing time" in my setup to make the shutters extend/pull back the full way. Without it they extended/pulled back only about 80%.

Also, reading the manual more thoroughly it mentions that when the device is "unconfigured" (no mode set) the inputs S1/S2 for physical switches will not work. I cannot confirm this as I do not have or need physical switches in my setup.

I will be happy to test the changes in the PR mentioned above when I find the time. Is there a better way to do it except adding the new sections manually to my local files?

@SwoopX have started a PR for your device here https://github.com/dresden-elektronik/deconz-rest-plugin/pull/7683 You have a DDF and a more complete code to edit for the xml

[sahnetorti]

I have applied the changes manually to my installation. I can confirm that

• "Device mode"
• "Calibration opening time"
• "Calibration closing time"
• "Motor state" all work.

I can control the shutters through Phoscon and through Homeassistant (via deconz integration).

In my install I cannot test the settings for

• "Child lock"
• Switch type"
