@Ranjib There's no easy way to use the same channel both as Diurnal and Moonlight? Or maybe a simple way to control light enable/disable with timer without using macros..Here a screenshot of my timer, the macro I deleted, it was only one time needed...
Let me know if you have any idea.. Thank you!

Alright, I had a look at the code for the PWM-profiles on github and diurnal works with a cosine to the power of 3. The profile looks like this for different min/max settings:
The diurnal profile is at the minimum value outside the start and end times. In between the Start and End Time it ramps up and down.
At exactly the start time (denoted 0) it starts ramping up from the minimum, to the maximum. This takes about 1/5 or 20% of the time interval between Start and End. After about 1/10 or 10% of the interval the light is in the middle between minimum and maximum value ( in the plot: (80%+10%)/2 = 50% )
The same thing happends towards the end, at about 4/5 or 80% of the interval between start and end the light starts ramping down. It will have fallen half the way towards the minimum at about 9/10, or 90% of the interval between Start and End. At exactly the End time it will reach the minimum again.
Practical Example:
I set my light to Minimum 0% and Maximum 80%, since my light is a bit too strong, between 08:00 and 16:00.
It will slowly start up at exactly 08:00, reaching 80% shortly past 9:30 (20% of 8 hours are about 1 hour 30 minutes).
A few minutes before 14:30 it will start ramping down, reaching 0% exactly 16:00.
Something I saw as well, which @Ranjib mentioned in another thread:
there is a light profile called "composite", which seems to stitch together different light profiles for their respective programmable interval. In my case I could use this to, for example, have a diurnal between 08:00 and 16:00 and afterwards run a much weaker lunar profile between 16:00 and 08:00.
It's not exposed in the GUI yet, put I'm hopefull that I can either set this manually or wait for the update.
I've read on this thread about the "Composite" PWM Profile. It is usable? In this way we can solve all our complex to use the same channel during the day but also as moonlight...
I was also thinking about the possibility to add a button inside the Auto light menu to "Enable this channel as moonlight" and then set a value for the intensity (a fix value, without moon phase should be enough)
If tgere's interest I can open a feature request on GitHub.. Please let me know! :)
I don't think so. Today is 3rd day I'm trying to install it on different hosts - from oldest Raspberry 1 (at least started), next is Raspberry Pi Zero W, and also tried on Orange Pi Zero 2W. At ALL boards I see error that embedded rpi driver cannot be accessed:

I installed it on a pi zero w using this setup.

I am getting a similar error with a fresh install on Pi-3 when installing Reef-Pi V6.0.
I have previously run V5.1 successfully so I did a fresh install with 5.1 using the exact same process and did not get the error. Tried V5.3 and got the error again. I have tried this several times with the same results.

I understand that since RPI foundation removed old methods of GPIO access, there is a temporary work around to revert the kernel in bookworm back to Kernel 6.1.74, which still supports the older methods of GPIO access. Try:
sudo rpi-update d86b5843d68b9972a5430a6d3da1b271cfc83521
I've not tried, but came across this in my reading as I need to redo my reef-pi set up as my 24vdc power supply went up in smoke and took out my system with AC power getting through to my goby hat and taking out sections of the PCB tracks
I hope there is still life yet in reef-pi as I was just about to get on with rebuilding my system.......

I believe so, https://github.com/reef-pi/reef-pi/issues/566 think it lists it as PCA9685 - wether thats the same or not

There's definitely still life in it, i just think one has to lower their expectations since the last "update" as we all know was Nov 2022...
By lowering expectations (and i am by no means having a dig at anyone here that is reading this) - i mean either stick with Raspberry Pi 4 and Raspbian Bullseye OS or if go Raspberry Pi 5 you have to use Bookworm and revert to an older kernel.
Which doesnt matter at all in the grand scheme of things as long as it's stable (its not like reef-pi chews up resources) unless you have some real weird fringe-use case that no one has ever considered before and if you are exposing this direct to the internet then you should have the appropriate security measures in-place and not relyng on the latest OS update to hopefully keep you safe :p
The only time you may get stuck is if you go to use the Pi for other things besides the reef-pi software on it and the kernel version carries a bug against what you are trying to do (i like to keep things all separate).
Will the developer come back into the light and continue where he left off? who knows. As this is all open-source and no one getting paid for it it's a love job/project....so we have to be thankful it is where it is today....There is the odd github commit of package and dependancy updates as of late... Will someone else take on the task and fork it and go from there, who knows, i would if i were able to understand the language as in my own experience reef-pi sure beats all the other controller crap out on the market for what 90% of us want it to do and not having to rely on some one elses "cloud" or recording everything you do on it.

For what it’s worth I have just tried bookworm with that downgrade and I get in reef-pi the following so clearly something is wrong:
Failed to initialize i2c. Error:open /dev/i2c-1: no such file or directory
Failed load raspberry pi driver. Error:can't build hal pin 25: embd: your host ":" is not supported at this moment. request support at https://github.com/reef-pi/embd/issues
I’ve setup config.txt to match my working reef-pi setup and no change.

I'm trying to get my reefpi up and running using robo-tank controller with the lighting and DC module, Sensor module and 2 power strips. Everything is plugged in: module interconnects, power, float sensors, Ph probe, custom lighting dimmers to Meanwell drivers. Dosers.
I ran the robo-tank installation instructions for reefpi https://www.robo-tank.ca/reef-pi_Related_User_Manuals afterwards the reefpi blank dashboard comes up so I know reefpi is installed. When I click on connectors to start programming the ports I get this:
There is also a reoccurring error message:
