An overview of the what and how it is integrated in Domoticz (of course there are more connections between the different items, just showing how they connect with Domoticz):
System can be controlled with Logitech Harmony remote (also used to control TV, media center, receiver), wall-mounted tablet, dedicated z-wave remote, voice (Alexa...) and of course using regular wall switches (which will also work when Domoticz happens to be offline).
Tablet control is mainly done using Imperihome (really, a must have app, very responsive and great support for many platforms):


From within Imperihome dedicated apps can be started to control Sonos, Onkyo, Kodi, monitor electricity use and solar panels. I think I pretty much stretched to the maximum of what I can and would like to achieve. Maybe some automatic sprinkling for the garden in the future, who knows...
