I have had some issues with wifi mesh network that could or could not be related to the smart switches I have installed. I have about 20 wifi switches installed, and will have another 10 smart bulbs. Plus another 10-20 personnel devices. I am wondering if I should switch to a z-wave setup to keep general wifi stability. I have 200 mbps at the modem. I could easily switch to z-wave now in the same model before return window expires.
