Is it worth it to do the whole place ?

Hi guys, I am in the midst of renovating my place and though of replacing all the down lights with the yee lights down light so it’s a diy smart home …
My question - is it a good buy ? Or should I stick with basic led lights or only do portion of the house with smart lights?

Does it eat up your WiFi ? I am looking at 40 + down light
TIA

You just need a good router that can handle a lot of devices and good wifi coverage if it is a house. I have like 20 wifi devices (bulbs, heater, fan, air purifier, humidifier etc) and it all works well, but I am in a flat and I didn’t have to solve wifi coverage, one router is enough.
