Fire708- there are options for homekit according to the forums over there. One thing you may want to keep in mind is the price of Homeseer. It is rather pricey. The first of 2 sales just ended in may. I would suggest waiting for the black friday sale. It gives you time to save. Factor in the plugins you will need also.
ArborAgent- I am in a small 2 bd house so my setup is kinda small as compared to others. I run HS3 on windows, use philips hue, harmony hubs, A vera plus for the zigbee radio (new plugin written by the same guy that did the Fireboard) and also use the vera plus to middleman my voice recognition stuff using voxcommando.
I do all the typical monitoring of doors/windows/lights/motion/power/environmental things.
If I had to pick my favorite thing about my system is my coming home routines. one for store and one for work. When the door is opened a random greeting is said, given the temps of set spots, ac set, lights turn on , sensors activated, tv turned on to kodi and music partymode is started so I have music playing until i am ready to sit down and watch tv.
The fireboard implementation for me is all about overnight cooks. If you are interested, https:// forums.homeseer.com/showthread.php?t=196465
I have my events in there that you can look at and contemplate. The hard part is setting it up the first time. But afterwards, the only thing you need to change is the set points for the temp you want to be alerted on.
