GatorEye,
Curious if you are looking at some sort of conduit to your Homeseer server with the Almond +?
I'm still running HS2 and haven't upgraded to HS3 yet. One of the things I was complaining about was lack of webservices support. Then someone provided a script to support web services in HS3 so that is what I'd go with if I went that route. HS3 was too long in coming out, still seems unstable, and the UI still doesn't look great. With a product like Almond+ providing an interface to everything Zwave and Zigbee that would cover most everything for me. The only thing left is replicating the speaker client functionality. At that point HS3 just becomes a glorified scheduler.
I like the ability to have my own UI, own mobile app, and not be dependent on someone else's cloud. I think HS has a place if you are someone with a mix of various older technologies, but moving forward with things going the way of Zigbee/ZWave/BLE/WiFi I think something like Almond+ with their hardware ability to support these protocols holds more future in the long run. In the past year seeing all the new products that are coming out makes me believe that even more.
At some point I'm sure I'll install HS3, but right now I'm waiting on my Almond+.
