ᐅ Is it necessary to have LAN cables installed in the garage?

It really depends on the house.
For a low-budget option, I would also skip it and try to find another solution or possibly do it myself.

For a higher-end build with a nice garage, I definitely wouldn’t forgo having LAN, unless the LAN point is right next to the utility room and the issue can be fixed quickly with a drill. 😉

I would say that with a high-end build or, to put it bluntly, with ample wealth, you don’t worry about 500€, you just get it done.

As I said, I would save the 500€.

No, it’s not necessary. For example, we have a Zappi from myenergi. The connection is made using a wireless hub, which is installed directly in the utility room (of course, this also depends on the distance between the garage and the utility room).
But there are certainly boxes with a LAN connection as well. It just depends on what kind of box you want.

We have exactly the same setup, and the hub’s range is long but not unlimited. Personally, I would install at least one duplex or two separate (underground) LAN cables Cat7 (hopefully the electrician charges only about €50 difference for one or two cables?).
Sometimes a serial connection is needed instead of LAN (depending on the wallbox / inverter), plus a LAN connection, so all cables are used. That means it can get tight right from the start. For example, I have two wallboxes at the parking spaces but only two LAN cables (the solar technician said one LAN per wallbox is enough). Later, it turned out that an additional serial connection would have been better (due to the limited wireless range of the Zappi hub).

Ask the electrician how he arrives at the €500.
He should specify the material requirements and the labor involved.
Of course, it's difficult for me to compare with current prices since our build was about 7 years ago, but back then we paid around €100 for a twin cable to the farthest corner of the garage.
Otherwise, you need to decide if you can afford to absorb the €500.

We are building with a developer.
He says that because the cable has to go through the building envelope, it is a lot more work for him.

The problem is that we either accept the price or have to do without.

Unfortunately, we are tied to the electrician.

We can accept the additional cost if it really makes sense.

Is it sufficient to have a simple Cat cable installed and, if more LAN ports are needed later, simply mount a switch in the garage for additional ports?

CatDuplex costs significantly more.

Sorry, but what kind of electrician is that?
I can tell you that a 400-meter (1,312 feet) roll of Duplex CAT7 cable is available for 500 €.
In our case, the garage is also directly attached to the house, and there is nothing more than a hole in the wall (as with the interior walls). (For us, the cables also run through empty conduits.) How far would the connection to the router/server cabinet be? He should alternatively install an M25 conduit; you buy the required length of Duplex CAT7 cable at the hardware store and have it connected by the electrician (if it is an employee of that company and not the electrician himself) during the installation of the other LAN cables.
Reading something like this really makes you want to pull your tie off.

Why does a duplex cost significantly more? The effort is the same, since both cables are welded together and only “one cable” is pulled through!? Could someone explain what accounts for the difference in cost and why.
