Hello,
I didn’t find much using the search term "Astro," so I’m starting a new thread here.
We want to install electric shutters in all rooms.
At least in the bedrooms, I want the shutters to automatically open at sunrise.
As far as I know, this is called an "Astro" function.
I have no experience with this and would like to know from you which brands offer reliable products and how exactly these systems (especially the sensor part) work. If possible, I’d also like to know approximately what such a system costs per shutter (excluding installation).
I’m also very interested in hearing about your experiences and what you have installed yourselves.
For GIRA, I have seen there’s some kind of odd antenna that you attach externally to the window.
But such an antenna doesn’t look very nice and will probably fall off eventually (suction cups never held for me).
Also, I don’t want to install a separate antenna for every window.
We are also considering whether it makes sense to equip all other windows with such a sensor or to use a different kind of programming, for example to simulate presence during a vacation.
However, I don’t want to pay any price for this, and I have no idea what additional costs such extra features would cause per shutter.
We do not want to install a bus system, and I hope there are already wireless options available on the market.
The most important thing is the Astro sensor for the bedrooms.
Otherwise, our plan is to connect all shutters in the house centrally in addition to decentralized switches in each room, and to install an additional switch in one place for "raising/lowering all shutters in the house." We do not want a central distribution per floor.

Each roller shutter also has its own individual switch for direct operation. The astro switch is connected there as a "secondary unit."
The Gira astro switch also features a presence simulation.

I have Somfy Tahoma, and there are several ways to control the roller shutters! Either using the sunrise and sunset function in the calendar, or with Solaris IO, wind, rain, and sun sensors—though I don’t have those yet, they will come eventually.
I created dozens of scenarios, but eventually, I noticed they conflicted with my schedule. Either I’m still asleep and the shutters wake me up, or the astro function is useless because it’s already dark and raining outside. Or I get up earlier and have to open them manually because the sun won’t rise for another 30 minutes.
Currently, I only use the closing function for all the shutters around 6 p.m. (18:00) or when we leave the house as additional burglary protection.
Other gadgets, like smoke detectors, I only have one per floor because they are simply too expensive or incompatible.
For example, garage door control costs an extra 100 euros because it’s from Hörmann. However, the Somfy motor costs over 50% more.
I recently installed an infrared heater as an addition in the bathroom and also control it with scenarios, but had to go through EnOcean, which cost about 60 euros for an actuator and about 60 euros for the Somfy box extension.

You might as well install a bus system; in the end, it’s not much more expensive. That really does sound about right. Since we’re talking about new construction, why plan with limitations from the start? Can anyone provide some insight, @Mycraft maybe? Perhaps an example of the cost of KNX components just for roller shutter control?
As soon as some automation is desired... bus systems immediately become attractive... that's actually why they were invented, and not to take money from the average consumer.
What is certain is that if additional functions and control options are planned beyond a simple astronomical timer function, a bus system is more cost-effective than conventional installation.

We have retrofitted all the roller shutter switches on the ground floor from standard models to the “Thor” system by Jarolift, so that the shutters automatically go up at 7 a.m. and go down in the evening using an astrofunction (sunset time is determined by postal code).
In summer, we activate the associated sunlight sensors, which lower the shutters when the sun shines directly on the large living room windows to prevent the rooms from heating up too much.
In the bedroom (and other rooms on the upper floor), we did not install timers because we don’t want a bright bedroom at 7 a.m. on weekends. Also, I always pass the roller shutter switch when going to the bathroom, so operating it manually is not a problem.
On the ground floor, however, I find this type of shutter control very convenient because you don’t have to walk through all the rooms every morning and evening to raise or lower the shutters. Additionally, you don’t have to ask someone to operate the shutters when you are on vacation or come home late, which helps prevent burglars from noticing the house is empty due to open shutters.
Certainly, a central control system installed during construction would have been useful, but it would likely have exceeded our modest budget and was therefore not considered at all. Our timers cost €40 (49 USD) per switch and were upgraded gradually. For €240 (295 USD), we would never have gotten a KNX, bus, or similar system, but we are completely satisfied with our budget-friendly solution, which was easy and quick to install ourselves.
