Strange behaviour

[eulaersivan]

I have the following code:

if ("Melding_DonkerBuiten-3/1/13"==EIN) and chtime(16,00,00) and (NACHTMODE==AUS) then {
  write("Switch_Vijver_Ledverlichting-0/5/3",EIN);
  write("Switch_TuinMuurTL-0/1/38",EIN);
} else {
  write("Switch_Vijver_Ledverlichting-0/5/3",AUS);
  write("Switch_TuinMuurTL-0/1/38",AUS);
} endif

A Merten Argus 220 movement detector sends a value 1 when the brightness drops (it's getting dark outside). When I go to bed, NIGHT MODUS (NACHTMODE) is set ON.

As soon as it gets dark outside (but not before 16:00) and as long as I'm not in my bed, two lights should be set on:
- the light of the pond (vijver)
- the light in the garden (tuinmuur)

Works perfect. Light went on around 18:50 this evening. But I noticed that the light of the pond switches off after a while. The light in the garden stays on. And I don't understand why.

In eibpc, I see that eibpc triggers an OFF value:

% 2012-10-23 19:37:23 [I]| [/I]Sender: EibPC | GA: "Switch_Vijver_Ledverlichting-0/5/3" | Value: OFF | Type: binary value | Write

But why is this value triggered? I have no clue at all.

In eibpc I also have written the following code to join eibpc with CommandFusion and to generate a web page. No other references to the light of the pond:

JoinToggle2GA(CFT,d184,"Switch_Vijver_Ledverlichting-0/5/3","Status_Koivijver_Ledverlichting-2/5/3")

CallSwitch(20,4,"Switch_Vijver_Ledverlichting-0/5/3","Status_Koivijver_Ledverlichting-2/5/3")

:begin CallSwitch(PageId, ButtonId, SwitchAddress, StatusAddress)
if pbutton(ButtonId, PageId)==1 then {
  write(SwitchAddress, !SwitchAddress) 
} endif

if change(StatusAddress) then {
  pdisplay(ButtonId,convert(PageId,$$)+$_$+convert(ButtonId,$$)+$_$+convert(StatusAddress,$$),LIGHT,DISPLAY,GREY,PageId)
} endif
:end

Tx for your help.

BTW No problem if you prefer German.

Avoid using the else-statement. It will likely not do what you want. Try to write code that does not use else. Look close at the manual for the else statement.
Did I already write you should not use else? Do not use else-statement.

As soon you rewrite your code without else it will work.

if a then b else c endif
will expand to

if a then b endif
if !a then c endif

if b does something to change a then you got a problem with forecasting the results.
