I like that it is integrated with Home Assistant, so easy to add new nodes! Also if one node goes down then others will automatically start working again when they come back online. If there's no internet connection for any reason (even temporarily), all other nodes just sit idle waiting until an Internet conection comes up or time expires. It can be tricky setting everything up at first but after about 10 minutes of reading documentation you'll get used to how things work. We have been using this as part of home automation project where we use Z-wave switches which are controlled from inside my house via WiFi network.
