Hello everyone,
I was asked today if I was knowledgeable in the field of automatic watering, I simply replied that I would talk about it on the Gladys forum 
My friend is therefore looking for a way to automate the watering of his large garden.
Today, he has a water tap to which he connects several pipes in order to distribute them over the entire surface.
But the water flow is quite low, too low to water the entire garden at once.
He then thought of either buying several single-pipe modules, or a module with several independent outlets.

He is not very handy, so he is looking for a turnkey solution, a smartphone application would be enough for him.
I therefore call on you to find out if there are other solutions, or devices that you recommend to me.
We have not discussed the budget, but I think he is ready to pay the price if the solution suits him.
Thanks in advance for your help.
