“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.” – James M (US)

“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.”
Steve A (UK)

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. 
Aaron (US)

“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!”

Why Choose HomeSeer?

HS3 is the culmination of nearly 20 years of research and development. Our software is simply the most flexible home automation program ever devised. In a nutshell, if you can’t do it with HS3, it probably can’t be done at all! Check out these important features:

Reliable & Fast Locally Processed Automation
HS3 processes all your automation locally, ensuring the highest level of reliability and performance. You won’t experience the “delays” that are common with typical cloud-managed ‘smart hubs’ and ‘gateways’.

Safe & Secure
HS3 stores all your sensitive information on your PC at home, never in the cloud. This helps to prevent hackers and prying eyes from seeing your personal data and custom home automation schedules.

Our MyHS web service simplifies the process of controlling your home remotely but is not required to automate your home. Your HomeTroller will continue to control your home 24/7, even when the internet is down or there’s a web service outage.

Works with (Nearly) Everything
HomeTrollers are designed to work with thousands of products from hundreds of manufactures using most popular home automation technologies. With HomeSeer, your imagination is your only limitation!

Leverage The Cloud
Leverage the latest technology with your HomeSeer-powered home! Use voice assistants from Amazon and Google and create IFTTT ‘applets’ that integrate with more than 300 web products, apps and services from around the world!

With HomeSeer, your smart home investment is secure. Because our systems are locally managed and not dependent on a company-managed web platform, you can rest easy about the future!

Smart Home Apps

HomeTrollers are designed to be programmed with any computer running Chrome, Safari or Firefox. We also provide two mobile apps (HomeSeer Mobile & HS3Touch Client) for system access and control. A third mobile app (Z-Tool+) simplifies Z-Wave smart device setup.
