Electric ball water valve

Hello All,
i have bought myself a watervalve witch i want to use within homey. At the front of the house i want to make a water tap. I want to be able te cut off the water when i am not at home. For this i have bought the following water ball valve
before i can use this valve i need a proper switch. Now i have bought a sonoff basic smart switch but i don't think this will do the job.
i need a wisselschakelaar (is this called a changeover switch in english?).
This is the drawing that comes with the valve
So my question is witch switch can i use so that homey can open and close this valve.

But you can look at the popp strike lock, this is nothing more the a zwave relais wich is supported by homey.
Or this with wifi
The 433 version i do not know as i do not have but i guess it should work somehow
Thanks
Here is some info to setup the wifi one

I today finaly did get it working with a 2 relay board.
I needed one of these to programm the ESP01

But you can also get them from ali
Connect the neutrals togather and the L connection of Sonoff 1 connects to blue and the L of sonoff 2 connects to brown.
Turn on 1 to close the valve.
turn on the other to open the valve.
Function is the same as the switch in the schematic, only you use 2 switches in stead of a change over.
Be aware that you turn off 1 efore turning on 2 and the other way around.
1 is wifi and 1 is wifi and rf
To make it work safe you can(should) buy a sonoff dual. This has a sync mode acording to the github feature request, where only 1 is allowed high:
https://github.com/xoseperez/espurna/issues/491
of course also put a fuse in line with the neutral, so if both are activated you atleast
the forum below uses 2 extra relais to get a hardware sync
But then you would only need the close circuit to be powered when there is a leak detected.
This way the valve would not be powered all the time and makes it also a bit saver
Except for the wait, the firmware already does that if you set the synchronization mode to "Zero or one switches active". In this sync mode, the firmware will check it never has more than one relay ON. One thing thou: right now it will action the relays in order, so there is a change to have both on for a few millis.
How is it wired exactly?
Operating the Switch 2 using a toggle switch and parameter 20 set to 2:
- Change switch position once:
- Change switch position twice:
i can't find out what is parameter 20.Change the state of the connected load to the opposite one (S1 switches 1st channel, S2 switches 2nd channel),
Change the state of 2nd, 3rd (S1 switch), 4th and 5th (S2 switch) association group to the opposite one.
Set maximum level of devices associated in 2nd, 3rd (S1 switch), 4th and 5th (S2 switch) group.
i look for a wiring diagram
