“Best Automation Software Ever! I’ve tried Smartthings, Home Assistant, Vera, and Donomitcz and HomeSeer is by far the best and most compatible system I’ve used. Also response times are incredible, no more waiting for the request to go out to cloud and back. Also works great if your internet goes down.”

“Homeseer HS3Pro My conversion for Vera Edge has been fairly painless, although some of the Homeseer UI isnt as easy to use, the biggest gain is MQTT and control over what running on my home controller. The homeseer store transaction was easy, and homeseer support has been excellent.”

Works better than all the others.
I’ve used ISY (for 5 years), Vera (for 5 years), Wink, InControl, and several others briefly OpenHAB, Home Assistant (HAS), and smaller players. While HomeSeer is more expensive, it is far more stable than Vera and far easier to setup than the free alternatives like HAS & OHAB.

“Flexible Home Automation HS3 is by far the most flexible home automation software. This is definitely one of those you get what you pay for scenarios. HS3 has the largest amount of things it works/integrates with and it’s flexibility is always increasing. Very happy with my purchase!”
