What is Control4 4Sight, and do I still need it?

The short answer. 4Sight is Control4’s subscription service for systems installed before April 23, 2024. It is what lets the Control4 app control your system when you are away from home, and it carries Intercom Anywhere, voice control through Alexa and Google Assistant, and When >> Then personalization. Control4 says its systems work locally without a subscription, so you do not need 4Sight to run the house from inside it. Whether you need it comes down to whether you use those away-from-home features. IntegrateIT, a Control4 Platinum Dealer with a Control4 Certified Showroom in Overland Park, Kansas, checks this for owners across the Kansas City metro.

Owners ask about 4Sight in two moments. One is a renewal notice they do not recognize. The other is the app that stopped working at the office or on vacation. Both have a plain answer once you know what the service is for. Everything about the product below comes from Control4’s own pages. Where those pages stop, we say so.

What 4Sight does

Control4’s documentation describes 4Sight as the subscription that lets you use the Control4 app to reach and control your system from anywhere in the world with an internet connection. The same page lists the other things it carries:

Feature	What Control4 says
Remote access	Control and status from the Control4 app when you are away, with an internet connection
Intercom Anywhere	Needs an internet connection and an active subscription
Voice control	An active subscription enables the Alexa and Google Assistant integrations
When >> Then personalization	The tool for building your own simple rules is unlocked with the subscription
Apple Music	Described as available to 4Sight customers

Notice what the list is made of. Every line is a feature that reaches your system through the internet, or through a cloud service, rather than a button on a wall. That is the clue to everything that follows.

What still works without it

Control4’s services page says Control4 systems work locally without a subscription. Local operation means the system running inside the house, without a cloud service in the loop.

Here is the limit of what Control4’s pages tell us. They list what a subscription enables. They do not describe, line by line, what every app, every software version and every account type does the day after a subscription ends. We would rather say that than guess for you. When we assess a system we check it on your account and your software version, and we tell you what we see.

4Sight or Control4 Connect: which one is yours

This is the question behind many confused renewal emails. Control4 says 4Sight is only available for systems installed before April 23, 2024, and that for later installs Control4 Connect is the required software service that replaces it. So the answer depends on the install date:

• Installed before April 23, 2024: your remote services are 4Sight.
• Installed after that date: your system uses Control4 Connect, which Control4 describes as unlocking remote access, Apple integration and more.
• Not sure: ask your installer, or ask us. We check it during the assessment.

Control4’s own pages use different words about whether the service is optional or required, depending on the page and the system. That is one more reason to read the notice on your own account rather than a forum post.

Who holds the account: you or your installer

Control4 says owners can manage their own 4Sight subscription and update card details in the Control4 app, and can buy 4Sight on the customer portal or in the app. Control4 also points new customers to a Control4 dealer. Control4’s owner page lets you renew the service subscription and edit your account details after you sign in at customer.control4.com.

Two situations make this harder than it sounds. In the first, the email on the account is the installer’s, and the installer has gone quiet. In the second, you bought a house and the account is still the seller’s. In both cases the fix starts with the account, not the hardware. We wrote both routes out: how to change your Control4 dealer from your own account, what to do when you bought a house with Control4, and what to do when your dealer went out of business.

If the app does not work away from home

Work from the cause Control4 names. Control4 says remote control needs an internet connection and an active subscription, so check in this order:

1. The subscription. Sign in to your account and look at the status. If it ended, the remote features are the first to go.
2. The internet at home. If the router is down, the controller cannot be reached, and the app will not find it.
3. The sign-in. Confirm you can still sign in to the account the app uses.

If all three look right and the app still reports the system as offline, we cover the checks in order on the Control4 repair page. That page answers the offline question directly, so we will not repeat it here.

So, do you still need it?

Decide by use, not by the notice. Ask yourself four things:

• Do you open the app from outside the house, to check a lock, a camera, the thermostat or a scene?
• Do you use Alexa or Google Assistant to talk to the system?
• Do you answer the front door from your phone when you are away?
• Do you have When >> Then rules you rely on?

If the answer to all four is no, the house may run exactly as it does now without the subscription, and Control4 says as much about local operation. If any answer is yes, that feature is what the subscription is for. Neither answer is wrong. The mistake is the middle one: paying for a service you do not use, or letting one lapse and finding out on a trip.

We do not decide that for you, and we are not trying to sell you a subscription. Control4 sells it to the owner on the owner’s account. Our job is to tell you what each feature depends on in your house, and to fix what is actually broken.

What a no-cost assessment covers

• The account: whose email is on it, and whether you can reach it.
• The subscription: which service your system uses, and what depends on it.
• The system: what runs locally, and what does not, on your software version.
• A short written note of what we found, so the next person who opens the system is not starting from nothing.
