I received my Blue series fan switch (VZM35-SN), and have it wired in with neutral wire. It works correctly as a normal switch (turning on and off the exhaust fan), but I am unable to pair it through ZHA to Home Assistant. The switch itself has the pulsing blue LED, and in HA ZHA when I hit Add Device it just says “Searching for Zigbee Devices…” until it times out. I was able to get my Blue Series dimmer switch (VZM31-SN) to pair fine. Does anyone have any ideas as to why the fan switch would not pair?
Details of my setup:
Home Assistant 2025.8.2
HAOS: 16.1
Zigbee dongle: Sonoff Zigbee 3.0 Dongle Plus
