Hour Meter for Lights?

Wouldn't it be nice to have a register where you could read the operating hours of every channel. I just thought of it when reading the box of my LV downlighter. It says 3000 hours but who really knows??? Below is a quick attempt to capture some data but it will take up a lot of resources if you have many lights. It will probably be in the ballpark with hours measured but be aware that if HomeGate restarts it doesn't count the hours of a light that was on at that moment.

once GetLightingState("Group 106 - Stairs") = ON then
begin
TimerStart(50);
end;

once GetLightingState("Group 106 - Stairs") = OFF then
begin
SetIntSystemIO("HourMeter", (GetIntSystemIO("HourMeter") + TimerTime(50)));
TimerStop(50);
ClearScreen; { Just so I can see that it actually works }
DrawText (GetIntSystemIO("HourMeter"));
end;

 

Ingo,
Off the track of your code but..

I'm not sure if they measure things the same in South Africa (presume it is an international standard), but in Australia the rated life of a lamp is when 50% have failed.

I was unaware of this until a few years ago we had a lot of lamps failing that ran 24hours. Apparently the manufacturers will test a type of lamp and when 50% fail that is the average lamp life. Note average being the operative word.

 

The Schedule Plus software has the ability to monitor the duration for which loads have been on. It can also raise an alarm when the duration exceeds some threshold for use for preventative maintenance.

 

Ahh... not being "Electrical" myself I wasn't sure how they measured it. I actually never bothered to check how often lamps fail until now.

Darren, is that functionality not in HomeGate by any chance? Should I run Schedule Plus just for that capability or use up all my timer resources as previously posted?

 

What ever happened to the dark lamp test .... the one that gives off dark light.

 

What - this one... ?
