I have 52 Zigbee plugs in total. 1 Iris v2 Beta, 1 SmartThings v2, 2 SmartThings v3, and 48 Iris v2. There are also 4 Halo smoke detectors, 1 ThingShield, and now 2 Xbees. All are acting as routers according to XCTU.
Do you have the latest firmware version in the Iris plugs?
Yes. The V2 plugs are all 0x20085010 which is the latest for that model.
You can find a list of the latest firmware versions in this thread.
