Reply to "super TIU mode with new WTIU"

I am in a similar situation running two TIU with WiFi.   In 2020,  I ordered a rev L to replace my original rev g TIU, but that order was cancelled and became the WTIU.   I do run them in super mode and using the MTH network.  Once my WTIU comes in, I will replace my oldest TIU and use it for the holiday tree layout.  I will test this out later this week.
