Adding a second TIU with WIFI

According to Barry's DCS Companion 3rd edition page 209 it's as easy as selecting 1 in "MTH" mode and the others in "Home" mode if I am reading it correctly.

I bought Barry's book too soon. So the home mode reads the WIFI off the first unit. Does the other TIU need to be set on TIU #2 or does it matter?

Each TIU must have it's own ID from everything I have ever heard and read.  The portion of that explains how to set up the multiple WiFis doesn't mention anything different than how you would treat additional TIUs normally.  I can check when I get home and have more time to skim the book.

Now this is a little more detailed information from Barry's WiFi Companion available from MTH.

Connecting Additional WiFi Interface Units in MTH Network Mode

To connect additional WiFi Interface Units for use with additional TIUs in MTH Network mode, follow
the instructions below:

• Set the second WiFi Interface Unit’s MTH/Home selector switch to Home.

• Connect the second WiFi Interface Unit to the second TIU by connecting the USB Port on a Rev.
L TIU to the USB Port on the WiFi Interface Unit. If the TIU is an older model, use a Serial to USB
cable to connect the two devices. In this case, refer to Part XII - DCS Upgrading and Remote Backup/
Restore, 4. Required Cables and Connectors later in this book for a description of the exact cable
that’s required.

• Attach the included antenna, and plug the second WiFi Interface Unit’s power supply into an AC outlet
and the power supply's cable into PWR port on the WiFi Interface Unit.

• Wait a minute or two for the WiFi Interface Unit's PWR, Wi-Fi and TIU LEDs to light.

• On the first (master) WiFi Interface Unit, press the WPS button. The white WPS LED will begin flashing.

• Immediately press the WPS button on the second WiFi Interface Unit. The WPS button must be
pressed within 1 minute. The white WPS LED will begin flashing.

• Wait for the white WPS LED on the second WiFi Interface Unit to come on steadily, and then turn
off.

• Select and open WiFi settings on the smart device.

• Choose the MTH WiFi network from the smart device's list of wireless networks.

• The smart device should indicate that it is connected to the MTH WiFi network.

Repeat the above steps for any additional WiFi Interface Units.
By using this method, these additional WiFi Interface Units will connect to the WiFi Interface Unit that
was set to MTH mode as if it was a router, thus allowing the DCS Application to connect to the additional
WiFi Interface Units though the WiFi Interface Unit that was set up in MTH mode.

As Barry would say, "This and a whole lot more" available in the DCS WiFi Edition.

Marty,
I just got around to doing this today. Your instructions were everything I needed. I didn't even have to change the TIU number. Thanks for your help.
     I have Barry's book but I bought the edition before the WIFI came out. I was going to buy it and have him sign it but we know how that worked out. Once the new TIU's and new WIFI remotes come out someone needs to do a new edition adding the changes to the original book. Maybe someone could split the royalties with Barry's wife.
