You really need to know before you start swapping hardware. Have you been through the diagnostic layers?

• Power supply (important if you’re running on a Raspberry Pi).
• Local interference (the USB cable supplied with the SkyConnect is not really long enough).
• Network interference (has your neighbour changed their wi-fi channel?).

Even if the upgrade is to blame, you need to know why - another integration/coordinator may be just as bad.

Lots of good advice here:

Zigbee networks: how to guide for avoiding interference + optimizing using Zigbee Router devices (repeaters/extenders) to get best possible range and coverage

Who is this guide for? I have tried to make this guide to be a comprehensive collection of the most basic yet essential tips with a set of actions and best practice steps that should be applicable to all types of Zigbee setups, regardless of what type of Zigbee adapter/gateway/hub/bridge/devices that you are using, however, it has been written with a point-of-view in mind of Zigbee solutions that use a Zigbee Coordinator adapter locally via USB dongle/stick or remotely using a serial server ove…
