I don’t know anything using WiFi that would meet the required specs (note the 16A rating in the picture). Or did you just mean the device you are replacing is WiFi?
The Fibaro model you list is zwave, not WiFi, but more importantly can only handle 8A, so I don’t think it’s a match.
If zwave is OK, Heatit has a model that looks like it might suit. It can control devices at the same specs (6 up to 16A). However, it does need a separate low voltage power supply for its radio.
It’s expensive for two important reasons:
It can control up to 6 16A devices independently
it’s spec’d for control of HVAC equipment (like fan motors), so it has features like galvanic separation of each switch.
But you’ll have to look further into the details. I’m not sure if it would require custom code or not.
