I've just setup my XBee this evening, so I'm possibly reading this wrong, but it does look like the IKEA Trådfri outlet is indeed working well as a Xiaomi repeater.
Four of the devices on the right are all Xiaomi and they have decided the like the hub, or maybe it's just because that's where they were paired, and haven't dropped off. For all but one of them that is a Xiaomi motion sensor upstairs, this makes perfect sense, because they are closest to me.
The three devices in the middle are two Sengled bulbs and a Centralite leak sensor, and they have chosen my Trådfri outlet in the living room, which makes sense, because all three are closest to it.
The other five devices on the left are upstairs are all Xiaomi and are closest to the Trådfri outlet in my bathroom.
Three leak sensors are offline. Two are Xiaomi, but this is my fault for not checking them when I had the incident with the Trådfri bulb, so I should be able to just pair them in place with the Trådfri outlets.
Again, maybe I'm reading this wrong, but the Trådfri outlet appears to be an absolute success as a Xiaomi repeater and they are super inexpensive. What have you found so far?
[Edit] Confirmed. These do indeed repeat Xiaomi and other Zigbee devices. No more dropping devices since putting these in place.
