Logic assistance please

Hi Guys,

Been messing around with the logic on my colour spectrum.

What I want to achieve is (I think) fairly simple. But I cant seem to get different times to work.

I have a PIR in the hall, which triggers the hall lights. Depending on the time, it will turn on 18% or 38%. It works fine before 11pm, but then after that time it doesn't turn on the group at all.

Any assistance would be greatly appreciated

Thanks!

once (GetLightingState("Hall PIR Trigger") = ON) then
begin
if (time > "11:00:00 PM") and (time < sunrise) then
begin
SetLightingLevel("Hall PIR Switch", 18%, "8s");
end
else if (time > sunset) and (time < "11:00:00 PM") then
begin
SetLightingLevel("Hall PIR Switch", 38%, "8s");
end
end;

once (GetLightingState("Hall PIR Trigger") = OFF) then
begin
SetLightingLevel("Hall PIR Switch", 0%, "12s");
end;

 

Your problem is the time can never be greater than 11pm AND earlier than sunrise. If you think about it you are asking for a number greater than 23 but less than about 7.

Try if (time > "11:00:00 PM") OR (time < sunrise) then

 

ahhhhh ok that makes sense.

if the above statement doesn't work, should I then try 3 time periods?

1 to cover sunset to 11pm, then 11-11:59:59 and another for 12am-sunrise?

thanks for your reply Ashley!

 

thanks again for your help, Ashley. I've slightly changed the code. the PIR is enabled/disabled via a schedule so there is no need to specify a start time as the group will never turn on before sunset - 10mins.

once (GetLightingState("Hall PIR Trigger") = ON) then
begin
if (time < "11:00:00 PM") then
begin
SetLightingLevel("Hall PIR Switch", 38%, "4s");
end
else if (time > "11:00:01 PM") OR (time < sunrise + "0:15:00") then
begin
SetLightingLevel("Hall PIR Switch", 20%, "4s");
end
end;

once (GetLightingState("Hall PIR Trigger") = OFF) then
begin
SetLightingLevel("Hall PIR Switch", 0%, "12s");
end;

 

You can also do this without any logic. Assign your Hall PIR trigger to the dimmer channel. Then create another GA that is set to 38% or 20% via 2 schedules. In the dimmer logic tab, enter this GA and select Minimum. When the Hall PIR trigger is off (i.e. 0), this will be the minimum value so the light will be off. When Hall PIR trigger is set (255), the dimmed GA will be minimum and set that light level.

 

ohh I really didn't think of that!

damn, you guys are smart
