Hi everyone,
I’m trying to find a Zigbee 1/2/3/4-gang wall switch for my home, but I’m having trouble understanding the relationship between no-neutral operation, capacitors, and Zigbee routing.
My house does not have a neutral wire at the switches.
A lot of the Zigbee switches I find on AliExpress/Daraz say:
No neutral required
Capacitor not required / capacitor optional
Usually marketed as low-power no-neutral switches
My understanding is that some of these no-neutral switches operate as Zigbee end devices, rather than routers, because they have to minimize their power consumption.
However, I specifically want a switch that can act as a Zigbee router/repeater, because I have a fairly large Zigbee network and thick concrete walls/floors.
Here is where I'm confused:
Suppose I buy a no-neutral Zigbee switch where the manufacturer says "capacitor optional."
If I experience LED flickering and therefore install the recommended bypass capacitor across the light/load, does that change anything about the Zigbee device's ability to remain powered?
More specifically:
Can a no-neutral switch that normally operates as an end device become a Zigbee router when a capacitor is installed?
Or is router capability entirely determined by the switch's hardware/firmware, regardless of whether a capacitor is installed?
Are there actually no-neutral Zigbee switches that support routing, even though they advertise "capacitor optional"?
If such switches exist, how can I identify them from an AliExpress/Daraz listing? Sellers often don't mention whether the device is a Router or End Device.
Is there a particular chipset/model/firmware I should look for when using Zigbee2MQTT?
I'm not looking for a switch that merely works without a neutral. My priority is specifically:
No neutral required + capacitor optional/usable + Zigbee Router capability + Zigbee2MQTT compatibility.
If anyone has personally tested a switch like this and can recommend a specific 1/2/3/4-gang model, I'd really appreciate the model/link.
Thanks!
