The picino’s intension was to add the voice-control through Alexa, Siri and Google to the Bticino-system. And to remote control your Bticino items without additional hardware or Router settings. Homeserver1 didn’t supported voice control until now. As far as I know supports homeserver1 voice input from Alexa now. But I don’t know how good it works and if he supports other voice-assistants (like Siri and Google). But you need a Bticino homeserver1 hardware.
You can use the picino if you have an older Bticino-system (without homeserver1). You just need a MH200, MH202, F455 or Webserver in your system to connect to the picino.
If you already have a homeserver1 I think you don’t need the picino.
