Can you use smart bulbs without Wi-Fi?
Yes, some of the smart bulbs that you purchase from the market or on the internet can be used without a WIFI connection because some of them use Bluetooth to connect a phone.
Not only Bluetooth, but you can also use the Zigbee hub or the Zigbee network so that you can connect your smart bulb to your mobile phone.
This tells us that there are other protocols or ways in which you can make your smart bulbs connect to your mobile phone other than WIFI.
