I would like to jump in with some comments on HS2.
First my HA background:
Started with x10 over 25 years ago, bought one of the first controllers with hardware inputs made by Steve Ciarcia of Byte fame, also upgraded to Ciarcia's second generation controller and finally upgraded to Stargate, which controlled lighting in my house for 8 very reliable years.
Felt that the Stargate provided very limited expansion at a very high price and look at Homeseer 1.5 about 2 years ago. Personal problems prevented me to pursuit the upgrade until recently at about the same time HS2 was in late beta.
Tested HS1.7.4 for a couple of weeks, HS2 was forced down our throats and went live with HS2 after removing Stargate (no going back)
I am currently running HS2.0.2014 with ACRF, Doomotion,HAI thermostat, Ultralog, Caddx AWX and testing MCS temperature as well as USB-uirt also the backup plugin without any major problems.
Of course, I am still very far from using all of the capabilities of the plug-in's but keep adding more sophistication to the events almost on a daily basis.
I do not upgrade to any release of any software, except for MS to close the holes, when it is first out, let someone else be the guinea pig. I know that you testing time should be about the same if not more that your coding time and most small companies do not have the resources to spend the time required to test any product.
I have had my differences of opinion with Homeseer. I also believe that they probably need more resources in programming than in marketing, except that they are trying to make it BIG.....
Allowing integration of user contributed code in the form of Plugins is very dangerous and really do not object for HS to charge a reasonable fee IF and a very big IF they check some of the plugin code and stand behind the developer in troubleshooting and support of problems.
I am happy with Homeseer as I have notice that things have quiet down. Only a few individuals usually trying to code their own plugins have major problems. I really believe that I have made the right decision as thing are improving.
I do not agree with some of decision (upgrade NOW as HS2 has been released (but still a BETA product), but remember:
The grass is always greener on the other side of the fence, especially over the septic tank.
I apologize for the length, but felt I needed to speak up.
