We have a similar setup at the house and I can only say that adding the Alexa has given the WAF factor a serious boost. She even asked for a second one in an other room. Although if you are not in the US you must be creative to get all the skills you want. But, she has me for that and I'm just happy she has no problem speaking English to the 'house'. And the integration with Vera is rarely give problems, pretty stable indeed.
Even playing with the thought to build something for openLuup, but that will take some time as building a smart skill with discovery is not trivial. I did create a skill for Volkswagen Car-net so i can pre-heat the car before departure. That is one she loves too, and so do I.
