Based on other posts it seems that certain WiFi mesh networks may cause network connectivity issues with Homey if Homey has not been assigned a fixed IP address and your Homey is not permanently allocated to one of the Mesh access points (so it hops from one to another access point). The issue does not present itself when connecting Homey via an ethernet cable (so only via WiFi).
So you might want to reserve a dedicated IP address for your Homey (DHCP reservation) and link it to a specific access point. Normally you can configure both in your router’s settings.
Also, restarting your router and all mesh WiFi devices might already solve the issue temporarily, but it might return if Homey has not been assigned a fixed IP/access point.
