Thank you ixo65, looks great!

The light should be on in summer during office times from 8.30 to 17.00h.

In Winter time the light should be on from 6.00 to 15.00h.

You have not written anything about this kind of activation yet.

Who should suspect what you are up to? Not me....
I have no glass ball and can not walk on water ....

You can only get good help if your functional description is good.

Well, let's keep looking.

Also, the light that did go off at a certain temperature can go on again when it drops under the temperature  ...

Now you have changed the functional description again afterwards.

I do not constantly look at already written posts to determine that you again define requirements differently.

I change the program according to your wishes and then realize that you change the requirements later.

It's not fun that way. I will not do anything until you finally write what you want.

Dear Mr. Computer Wizard :-)

Need help with a lighting project.

I have 4 lamps to light a room.
In the summer when it gets hot, I would like to have the lamps gradually turned off at a certain temperature.

Here is a checklist of the requirements:
- At a certain room temperature the lights should gradually go off one after another.
  --> Eg.: 30°C first light off, 32°C second off, 34°C third off, 36°C all off
- if a light is turned off, it should not go on for a certain time (Eg. ~ 1h). To protect the light bulb.
- if all of the 4 lamps are turned off, then a separate lamp should go on.
- each lamp can be turned off manually
- The lights are bound to two timer with different time settings so I can switch from one timer to another.

Tell me if and how many money units do you need to accomplish this project.

Looking forward to your answer

That was your initial functional description. There is nothing about the fact that the light should turn back on automatically after cooling, if it was previously switched on.
My can create a program only to the specifications.

What is self-evident for you does not have to be self-evident for someone else.
