Arduino dashboard suggestions

Hi, does anybody here have real-world experience using Blynk or Cayenne for Arduino dashboards? I plan to make a home automation and I would like to know what do you suggest according to your experience. I would like to control lights, measure power consumption and display weather condition. I am able to make hardware for this purpose so my question is only about the dashboard implementation. Are there any limitations or issues? What about security? Thanks for the advice. Lubo
