Hello,
I’m trying to associate a Sonoff Zigbee Switch SNZB-01. I can do it when I put it near the coordinator, but when I try to pair it distant from the coordinator it doesn’t work. Obviously, despite it is far from the coordinator, it is near to a lot of routers (2 INNR bulbs, 5 Philips Hue and others).
I already succeded to pair other battery powered Sonoff products, such as SNZB-02 and SNZB-03 without problems.
