Second, because the switch casing is plastic there's a separate wire you need to connect to ground, which usually means unscrewing the ground wire from the box and using a wire nut to connect it to the switch, making install an even bigger PITA. Third, and most important for a larger deployment, they connect over standard wifi, which could be problematic if your wifi signal isn't strong enough over the entire house or if your router isn't powerful enough to handle that many devices on the network
I'd recommend going with a Z-Wave based switch for a whole house upgrade. Z-Wave is it's own separate network with very low power requirements and far greater transmitting distance than wifi, the only thing you connect to your home network is a Z-Wave hub to control the switches. I went with Zooz switches for my house

Metal body so there's no messing with ground wires in the electrical box, slimmer profile than the TL-Links for easier installs, and they're much more customizable. You can setup different scenes depending on how many times you hit the switch, once for a single light, two taps to turn on all the lights in a room, 3 or more taps to change colors if you have smart bulbs, etc. They're also the best option to control wifi smart bulbs, in that the switch doesn't control the power to the bulbs (always on), but it sends signals to the bulbs themselves to turn them on/off
