The HC Fibaro the interface is really the most pleasant of all the ones I've tested. (Vera3, ZwaveMe, etc.).
Version 4 brings new features "turnkey". For example, synchronization with a weather station Netatmo, or Philips Hue bridge, or creating graphics on consumption Electric, or the temperature of the different probes.
While providing advanced features and highly customizable.
Many bugs are still present, but the Fibaro teams seem to want to put term, with updates closer together.
So I do not regret this purchase, but be careful before embarking. Home automation is a hobby that is expensive and time consuming.
