Creating a Self Signed Certificate

To eliminate the problem of being warned all the time about the default certificate the first thing that is suggested is to creating a Self Signed Certificate.

  1. Create my INSTEON ISY Self Signed Certificate Now!
  2. Login using your ISY credentials
  3. Choose Generate and Install New Self Signed Certificate; this will install a new certificate in your ISY and reboots ISY

Configuring Remote Access

In order to access and control your ISY unit from the Internet (away from home) you will need to enable Internet access on your ISY and make sure your router configured to forward the ISY port. This process allows the ISY to get a real IP address from your Cable/DLS modem which is seen across the Internet. Many routers can auto-configure directly with the UPnP protocol and others will need to have it done manually. If you need to configure your router manually please see the below section Configuring a Non-UPnP Router.

Most Internet Service Providers (ISP) use dynamic ISP addresses. This means that your ISP address can change at any time.

  • Your ISP address can be found:
  • Use dynamic DNS services such as DynDNS or tzoDNS to assign a domain name to your dynamic ISP address

Configuring a UPnP Router

  1. Check the auto-configure supported remote access routers list, if not see Configuring a Non-UPnP Router below
  2. Make sure you have enabled UPnP within your router so the ISY can auto-configure your router
  3. In your ISY click on "File --> Enable Internet Access" to enable the ISY internet access. This will negotiate the port through the router and out to the Internet
  4. Verify your ISY IP address in the popup window, it should NOT be from your local network (a local IP would look like:
    • https://your.isp.add.ress - an example might be
  5. Using the address assigned by your ISP or a domain name from a dynamic DNS service you are now ready to access your ISY software from the Internet!

Enabling Internet Access

Enabled Access Message

When successful

Menu item Help | About will display the external IP address

  • Note the address is preceded with https as you will be using a secure port.

External IP Address

Configuring a Non-UPnP Router

If you do not have a UPnP router, or if File->Enable Internet Access returns "null" or fails, then:

  1. Get your ISY IP address, and write it down. Here is an example of what you might have:
    • My URL:
  2. If your ISY is on a DHCP (default behavior for most routers) then ISY's IP address may change. As such, if you plan to use remote access:
  3. Follow the information on to configure your specific router for port forwarding.
    • Find and select your router on the initial page
    • Select the program "HTTPS" on the following page for instructions specific to your router
  4. Using the address assigned by your ISP or a domain name from a dynamic DNS service you are now ready to access your ISY software from the Internet!
    • If you are using port 443 (the default) you can access your ISY using HTTPS which will automatically forward port 443 to the ISY.
    • An example might be
  • Once port forwarding is configured in the router you DO NOT need to use Enable Internet Access.

Port Number

If your router is complaining about port 443 already being used, it means that you already have another network device (in your LAN) which uses 443 and thus the router will only forward the requests to that device. To rectify:

  1. Make sure this is the case (port 443 is forwarded to another device)
  2. Change your ISY's HTTPS port
  3. Reconfigure your router (or let ISY do it for you after reboot)
  4. Your remote access URL will be https://your.external.ip.address:new_https_port
    • In the image the Port has been changed to 1443.

Port = 1443
