Hi all,  
I’m looking for some advice on my smart lighting setup. I have a feeling I’m crashing my Zigbee network and would like to verify a potential solution.  
My Setup:

- Relay: Sonoff ZBMINI, installed behind the main switch in a two-way/three-way switch setup.
- Lights: Smart Zigbee bulbs (Ikea).
  - Living Room: 2 light fixtures (5 bulbs total) on one circuit.
  - Kitchen: 5 spotlights on a second circuit.  
The Problem:  
When I turn off the lights using the standard rocker switch, all 5 bulbs on that circuit are completely cut off from power.  
My Questions:

- Is it true that by ‘hard’ powering off 5 bulbs at once (which also act as repeaters), I am destabilizing my entire Zigbee network? Could this be the cause of my unreliable Flows?
- Would replacing the current rocker switches with momentary (push-button) switches be a solution?
- The goal is to keep the bulbs permanently powered, and have the momentary switch just send a pulse to the Sonoff, which would then digitally turn the lights on/off. Is this possible with this relay, and if so, how should it be wired?  
I must maintain the classic look and feel of the wall switches (a requirement from my wife), so smart panels are not an option.  
Thanks a lot for your help!

Move the wire L-OUT to L-IN and the lamps will always be powered on. The Sonoff ZBMINI will signal to Homey when it switched on and switched off, so you can switch your smart lamps with a Homey flow.

Correct. The connected nodes need to find and connect to another available nearby zigbee router.  
Which can take a while (half hour? hour?), or even fail.
