I would suggest calling in a qualified electrician to take a look at it before your house burns down. It could be that you have an undersized wire or a weak circuit breaker that needs to be replaced. It could be tripping during those times because of power serges in the neighbor hood when there is a sudden excessive draw of power usage on the service at the same time.
Earth leakage trips are usually a neutral grounding which probably means faulty wiring.
Undersized cabling will burn and too much current on a circuit should only trip a breaker, not the earth leakage, as it should be an isolator and not a breaker. Live grounding usually trips the breaker too, so this is usually easier to isolate the problem.

What electrical items in your house are on or come on between 5am and 7am. DO you have central heating? Air con maybe? These might be coming on and tripping it.
Or do you have a lot of activity in your house between these tim ...[text shortened]... omeone have a bath between these times? Maybe a leak in your plumbing is tripping something out.

For some time now our earth leakage switch has been activating between 5am and 7am.
below are the dates.

I do not Know how to line up the above chart with the days,sorry about that.
I assume that by downfall you mean rain. Try using a water hose to wet down parts of the roof and side of the building on a clear day. Do small parts of the building at a time to see if the water is causing a short circuit to ground and blowing the fuse. If you really want to find the short circuit, over fuse the circuit and go find the smoke!!

There may be some small animal roaming the neighborhood about that time of day and causing the GFI to trip by running over or bumping against a piece of loose wire. Seems weird, but you might want to start putting out some dry cat food close to the switch box and then slowly moving it away from the switch box if there are any critters munching on the chow, to see if the pattern changes. Or even spread a light coat of flour around the switch box to see if there are any tracks left in it in the morning.
Just a suggestion

1st: okum's (sic) razor. The simplest solution is usually the right on. Change the gfi
2nd: You stated that it was tied to a motion detector. 5-7am is a time that some people let their dogs out, there may be early morning condensation on the outdoor motion sensor, which would cause the unit to fault when a dog ran by. The change in days could be a change in work schedule, causing different outages

none come on at that time
the house is dead at that time of day.
I have tried to think of all these things and nothing.
Nothing seems logical except deliberate and yet I can not think of how so?

As above, these faults can take a while to sort out.
You mention that you have "threats", what do you mean?
