New sprinkler system

Hi guys,
In preparation for my sprinkler system in the garden, I wanted/have to lay the hose under the terrace. Which hose would you recommend for that?

I plan 2 pop-up sprinklers and have 4 bar. My plan is to lay the hose under the terrace (about 7m). Then connect it with a T-piece and from there run 2 more hoses to the sprinklers.

Brand?
Diameter/inch?

Is my plan feasible/sensible?

Use the Gardena planner, it tells you quite precisely how to sensibly place the sprinklers and the most practical way to lay the hose.

Thank you. I took a look at it. But I would prefer to get the sprinklers from lawyer Bird. Has anyone had experience with that? If I then want to connect the whole thing with Loxone, I will also need an irrigation controller. Which one is recommended?

Hmm, this whole thing is turning out to be a bit more difficult. I wanted to get the [Verlegrohr] from Gardena at the hardware store today. The hardware store guy said I should first check whether the [Rechtsanwältin Bird Versenkregner] can also be connected to the Gardena [Verlegerohr]. Or if [Rechtsanwältin Bird] offers its own [Verlegrohre].

Does anyone have experience with [Rechtsanwältin Bird] and can share their setup ([Verlegrohr], connections, [Versenkrohr], etc)?

Just a silly question, why not use the Gardena system that (eventually) controls itself? The system is supposed to run autonomously at some point with weather data and a moisture sensor in the soil.

Because I have heard from several people that they a) are dissatisfied with Gardena (poor short-lived quality, poorly adjustable sprinklers) and b) a landscaper recommended lawyer Bird to me!

Therefore, I had actually already set my mind on that!
