Minimum Number of Devices for Zigbee Mesh Reliability?

Thanks for the heads up on that. I’m pretty sure I’m safe though if I am using Iris zigbee sensors and Iris outlets for the repeaters. I suppose I could be wrong as they just rebrand other products. But I am assuming Iris has already streamlined compatibility since they run such a closed system that anything branded as theirs should work together. I have to say that while I was never impressed with their hub, their products seem to be rock solid.
