    I have finally got around to installing my Ness Smartbell and configuring it to message C-Bus Matrix to trigger the doorbell sound over the MRA speakers.

    As the Matrix doorbell function still has some issues , I decided to make up my own little doorbell Logic/Scene to alert the house that someone is at the door. In the kitchen I have installed an Android touchscreen that is connected as a MRA source that also rings with the Ness Smartbell app.

    Started off with a few variables capture the current MRA Zone source and volumes to return them back to after the doorbell function was finished
    Code:
    {Variables for Doorbell Function}
    Ensuite_Source : integer;
    Workshop_Source : integer;
    Studio_Source : integer;
    Kitchen_Source : integer;
    
    Ensuite_Volume : integer;
    Workshop_Volume : integer;
    Studio_Volume : integer;
    Kitchen_Volume : integer;
    Then created the module to capture the status of the various speaker locations along with a couple of scenes to tie it all together
    Code:
    {Once the doorbell has been pressed}
    once (GetCBusState("WiredHouse", "Trigger Control", "Front Doorbell") = ON) then
    begin
    {Capture MRA Zone Sources}
    Ensuite_Source := GetCbusLevel("WiredHouse", "Lighting", "Ensuite Absolute Source");
    Kitchen_Source := GetCbusLevel("WiredHouse", "Lighting", "Kitchen Absolute") ;
    Studio_Source  := GetCbusLevel("WiredHouse", "Lighting", "Studio Absolute")   ;
    Workshop_Source  := GetCbusLevel("WiredHouse", "Lighting", "Workshop Absolute Source");
    
    {Capture MRA Zone Volumes}
    Ensuite_Volume := GetCbusLevel("WiredHouse", "Lighting", "Ensuite Volume");
    Kitchen_Volume := GetCbusLevel("WiredHouse", "Lighting", "Kitchen Volume") ;
    Studio_Volume  := GetCbusLevel("WiredHouse", "Lighting", "Studio Volume")   ;
    Workshop_Volume  := GetCbusLevel("WiredHouse", "Lighting", "Workshop Volume");
    
    {Set Volumes to Zero}
    SetScene("AmpOffDoorbell");
    Delay(3);
    
    {Set Volume on the 4 zones to 40% over 8 Seconds and set to touchscreen souce}
    SetScene("Doorbell");
    
    {Wait for doorbell to be answered or timeout}
    Delay(60);
    {Return Zones back to where they were}
    
    SetLightingLevel("Ensuite Absolute Source", Ensuite_Source, "0s");
    SetLightingLevel("Kitchen Absolute", Kitchen_Source, "0s");
    SetLightingLevel("Studio Absolute", Studio_Source, "0s");
    SetLightingLevel("Workshop Absolute Source", Workshop_Source, "0s");
    
    
    SetLightingLevel("Ensuite Volume", Ensuite_Volume, "8s");
    SetLightingLevel("Kitchen Volume", Kitchen_Volume, "8s");
    SetLightingLevel("Studio Volume", Studio_Volume, "8s");
    SetLightingLevel("Workshop Volume", Workshop_Volume, "8s");
                                  
    end;
    The first scene sets these zones volume to off, then changes the source to the kitchen touchscreen, then ramps the volume to 40% over 8 seconds.

    After a minute, it returns the various zones back to their previous source and volume settings.

    Heavy and convoluted, but think it should work well.

    Going to test it out tonight. :D

    Can you explain how you got the smartbell to integrate with C-Bus. I have not used one yet, but have had a quick look at it in the past and did not think it would integrate with anything - obviously I was wrong if you have it working.

    Hey Mick - This is my setup

    • Smartbell to sends a simple ASCII message configured in the 'Front Door Visitor Calling' section of the eGateway.
    • On the other end, I have the raspberry pi that is running C-Gate and NodeJS to listen for the message.
    • When it receives the message it sends a command to the NodeJS/C-Bus interface.

    Unfortunately the smartbell cannot parse messages with either ':' or '.' in them, otherwise I would have done it directly.

    From the experience I have had with Ness so far, I don't believe the smartbell is a real good product (one RMA for the eGateway already) and unless you are installing the M1 as well, the interfacing becomes very convoluted as you can see above.
