Change of control of Aereco ventilation system via Zigbee and Tuya: Bemko B6 10A vs Lovato SM1P0100

Hi all
I have a single phase Aereco ventilation system installed. Its activation triggers 3 fans. The control is in the main switchboard and consists of a Bemko B6 10A overcurrent switch and a Lovato SM1P0100 motor switch. The Bemko switch is on all the time and I start the ventilation with the motor switch. The solution is very inconvenient so I would like to modify it so that it can be controlled by some smart device that supports the zigbee protocol (because I already have that at home) and the Tuya app. Ideally it would also be some kind of switch in the switchboard. This would be a big simplification especially when the kids are supposed to start/shut off the ventilation which I don't like very much now.... I have found such wonders on a....o starting at £85. They seem to have overload protection etc. but I am somehow not convinced. The question is whether such a thing is ok to replace any of the components you have or whether to add them in between in a row.... or are there any other devices?

All in all, the protections themselves can remain, only the controller could be replaced with some kind of three-channel relay under Zigbee where you connect the contactors to the fans instead of the bulbs.

I dug into the subject and found that the fans in the grilles were unconnected. The thrust and howling gave the effect as if they were working. After all, there is one control unit connecting the ducts with one fan. This leaves me with the assumption that a 1-channel controller is sufficient. I will repeat the question of checking the ones from allegro are suitable and whether I can throw away the lovato switch.

If the fan is powered by three-phase then this Lovato must stay.
You simply have to replace the original controller with a relay under Zigbee with an added three-phase contactor.
