If you have good wifi, you don't need to wait. I have a two story house and the floor plan looks like a T-shape, so I basically have 6 different zones. I pulled Cat6 everywhere for decent AP coverage. Right now I have about 80 Meross light switches and dimmers, 6 wifi blinds, wifi garage openers, Ecobee thermostats, multiple Apple TVs, ton of personal devices - easily over 200 devices on the LAN, most of them connected to HomeAssistant. Instant status updates with no problems except for the occasional need to reboot a wall switch due to power issues. Meross has a tiny hidden button at the bottom of each switch that instantly reboots the switch.
I bought Meross products off Amazon in bulk and absolutely love them. I have single pole switches, 3 way switches, single pole dimmers, 3 way dimmers, and a few smart plugs, power strips, and RGB bulbs.
PS: I even have a few Z-Wave devices and bought Zooz Hub ZST10-700 to work with HomeAssistant. I use these to measure power consumption on a garage freezer and a space heater. As long as the Z-Wave devices are close to the hub, there's no issue. But oddly enough they sometimes send negative power usage data which HA complains about.
