30-Day trial of HCA Plus

To give everyone a chance to experience the power and flexibility of the Home Control Assistant we offer a free 30-day time limited trial of the HCA Plus edition. The trial version creates a file that can be loaded into the purchased version of HCA so all of your work during the trial is ready to go.

The trial of HCA is fully functional with no features removed or limited. This lets you test out all of HCA's features for 30 days. After the 30 day period expires, the software no longer runs.

Get started with the 30-day trial


Purchase an appliance computer for use with HCA

For you to get the full function of all that HCA does, it must run 24/7 on a Windows computer. While you are free to use any computer running post-XP Windows (including Windows 10), many users find it simpler to have a dedicated machine for HCA. A machine that runs only the HCA Server application and executes your design. From any other computer you run HCA as a client when needed, connect to the server, and update your design or check status.

[If the last paragraph is not 100% clear, that is what the Getting Started Guides are all about. The Getting Started with Client Server gives you all the details of this multi-machine approach step-by-step.]

Here at HCA Central we looked at a lot of these kinds of computers and found one we like a lot. Several HCA users also use them, and they really like them too.

We are making them available to the HCA user community

All "Buy Now" purchases are made using PayPal, so a few helpful tips about purchasing with PayPal that will make things go much smoother...

Once you complete the purchase with PayPal we get notified you have made a purchase. We then send you download instructions for what you purchased and a registration key. Usually the download email arrives on the same day you purchased if made during business hours and the next morning if made at other times. At the slowest, you should receive email from us within 2 business days after you make the purchase with PayPal. If you have not received email from us within that time, please contact Support and be sure to include a phone number as occasionally our emails get killed by junk mail filters. When that happens, we need a different way of contacting you.

If you are purchasing an upgrade please allow extra time for the download email to arrive as processing is not automated - we check the registration database to confirm your previous purchase. If you have not received the download email within 48 hours please contact support.

Before purchasing with PayPal please check that the email address your PayPal account is linked to is correct and is your current email address. This is the way we contact you to complete your purchase and if the email address in your PayPal account isn't correct we will be unable to do that.
