Water leak "protection" in the house connection?

I would like to possibly install a safety valve in the water supply line of a house connection.

It should close automatically in case of major problems, warn in case of minor problems, and allow monitoring of consumption on the PC.

It is a semi-detached house that is about 25 years old. The picture shows the installation in the supply room. The distances between the individual components in the main water line are relatively tight, so an additional device should require only little space.

The water line with the small diameter goes in front of the house for watering the garden.

I have a leakage sensor in the HAR that closes a solenoid valve in the water pipe.

I have a leak sensor in my HAR that closes a solenoid valve in the water line.

Thanks for the tip!

In this case, I am not concerned with individual rooms to be monitored, but with the entire water installation.

For this, the flow rate should be monitored at the house supply. Software could then analyze irregularities or a permanent small flow, display it graphically, and possibly close a valve in the house supply.

I found a product on the internet that meets my expectations. Has anyone had experience with
GROHE SENSE GUARD
or a product with similar features?
