For nearly a year now, I’ve had good Zigbee reliability with ST. However, I have an issue I can’t solve now:
I had a bathroom remodeled in my house. During construction, I powered off some of my Cree Connected bulbs for a few weeks. When powered back on, two of the bulbs would no longer respond to control commands. Also, more recently, two of my ST multi sensors in the same room have stopped working. There are 4 Cree connected bulbs in the same room. Two work 100% reliably, the other two barely at all (but sometimes respond). The room they’re in is on the fringe of Zigbee range from the hub, but there are some other Cree bulbs and a Sengled bulb between the two that could (do?) act as repeaters. Here’s what I’ve tried to fix:
-Factory reset both bulbs and re-join to ST.
-Removed bulbs from ST and re-added.
-Replaced one of the bulbs with a new bulb.
-Powered down all zigbee devices that could act as routers and powered back on.
-Factory reset nearby Sengled bulb that could be a router, re-joined to ST.
-Checked/changed channel of wifi network.
-Powered off wifi AP for testing.
None of this gets those two devices to work reliably. It really seems like a Zigbee routing issue, but I don’t have any tools to troubleshoot this sort of thing. What can I try next?
