How to: Flash SonOff USB Dongle to be a Zigbee Repeater/Router & Set Transmit Power

I purchased a Sonoff dongle E and used @Stan1 technique to flash the repeater file to it. I saw it upload the file on the Putty software window. I'm not sure it is extending my mesh. I have 3 sengled bulbs that I want to connect to the repeater instead of the hub. In the ZigBee graph I see this

I reset and re-paired the bulbs prior to taking that graph screenshot. I have a group setup this way

Using a basic rule machine rule, I use a button press (on a Zooz z-wave switch set on smart bulb mode) to try to toggle the group as a switch on and off. Only one bulb turns on and off. Shouldn't the graph be showing the bulbs (preferably connected to the repeater)? I know I must be doing something wrong.

Here is the ZigBee table

From the individual device pages, I can toggle on and off with no problem.

Does anyone have any suggestions?

TIA
