PIR, Shac, logic control and schedule

Hi I have a PIR and edlt controlling some lights in a bathroom which is programer with min logic and a schedule in a shac to do ..
100% light level 07:00 - 23:00
15% light level 23:00 - 07:00
I now want to set a scene for the lights and some LED strip and disable the PIR, this I can get to work.
The problem I have is trying to get the lights to run at the correct level for the time after turning off the scene.
Has any one any smart ideas?

 

Can we take a step back and define what you are trying to achieve from a Physical level first, (pretend you are the customer asking me, the programmer to do it)

my assumptions.
you want the sensor to turn the light On and Off,
And the edlt to turn them on and off.
Overnight you only want this only come on to 15% brightness from either device, or does the switch still need to do up to full brightness?

also what is the function of the scene?
Disable the sensor so the light doesn't turn itself off.
Turn on Bathroom light (does this follow the relay logic? Or needs to be brighter than 15% overnight?)

 

In our bedroom ensuite I use a similar schedule which I imagine is a common config to set a dummy GA to 100% or 30%, and minimum on the dimmer to provide night lights.

If I wanted to allow a scene to override, and return to the correct dimming state when the scene is not set, then I would approach it with an extra dummy GA and coding:

Dim_Level_From_Schedule_GA = 100% or 15% set from the schedule
Dim_Level_From_Scene_GA = 100% when Scene is set, 0% when scene is not set
Dim_Level_To_Use_As_Min_On_Output_GA = Maximum of these two (Dim_Level_From_Schedule_GA or Dim_Level_From_Scene_GA)

OT: The dummy GA that is used as the min on the output, I also put as a spare button on the DLT as short press = ON. This provides a simple override when my other half often has to get up early for work and wants 100% lighting.

 

The SHAC has a StoreScene procedure to save the current values in the specified scene. So create a scene containing the values you want to restore. When the PIR triggers (on a dummy ga) , save the scene then set whatever you want. When the pir ga turns of, set the saved scene.

 

Hi Everyone thanks for your replies and Help. sorry if i created some confusion with the lack of the full scope!


100% Bathroom light level 07:00 - 23:00
15% light level 23:00 - 07:00
PIR is set to trigger the light on with the dimmer o/p set to logic min.
set a schedule to run
100% light level 07:00 - 23:00 GA on the dimmer logic
15% light level 23:00 - 07:00 GA on the dimmer logic
scene set on edlt
lights at 100%
PIR Disable
GA for dimmer logic 100%
scene set off on edlt
Lights bathroom 0%
Led tape off
PIR disable off
GA for logic 0%

schedule with a dummy GA to 23:00 to 7:00 set to 100% (true)
event script looking at this GA and if its true set GA for logic to 15%

it works but have I over complicated it?

Thanks for all your help again!

 

If you use a single GA it will get overwritten by your scene handling, and when you want to return you do not know what time of day to apply.
Separating the inputs and outputs allows you to keep a running record of time of day.

I haven't moved onto LUA yet but the code below may serve as an example.

Code:

    set a schedule to run
    100% light level 07:00 - 23:00 GA_input_from_schedule
    15% light level 23:00 - 07:00 GA_input_from_schedule

    Once SceneIsSet("scene_on_edlt") then
        begin
        SetLightingLevel("GA_input_from_scene", 100%, 0);
        end;

    Once NOT SceneIsSet("scene_on_edlt") then
        begin
        SetLightingLevel("GA_input_from_scene", 0%, 0);
        end;

    Once (HasChanged(GetLightingLevel("GA_input_from_schedule") OR HasChanged(GetLightingLevel("GA_input_from_scene") then
        begin
            If GetLightinGLevel("GA_input_from_schedule") >= GetLightingLevel("GA_input_from_scene") then
                SetLightingLevel("GA_output_on_the_dimmer_logic", GetLightingLevel("GA_input_from_schedule"), 0)
        else
            SetLightingLevel("GA_output_on_the_dimmer_logic", GetLightingLevel("GA_input_from_scene"), 0);
        end;

 

Thanks for your help works a treat!
Good LUA example!
