Building a Smart Home Network

 Last summer, I bought a SwitchBot thermometer and a SwitchBot Hub mini, converting Bluetooth and infrared signals to WiFi.
I've been yearning to check my room temperature via Amazon Alexa, but for the first few months, I hadn't connected my thermometer to WiFi and synched with my Alexa network.
SwitchBot thermometers are excellent without a WiFi connection.

I set up my first intelligent appliances network with my Amazon Echo and SwitchBot series because I will need this knowledge shortly.

At first, I was a bit annoyed when connecting my SwitchBot Hub mini to the WiFi; it accepts only WPA2-encrypted 2.4GHz WiFi.
Even though I put my iPhone with SwitchBot controlling app, my Hub mini, and my thermometer around the AP, it took me several minutes to configure the WiFi network.

In the past, AP ads said that 5GHz WiFi is faster than 2.4GHz WiFi, which I doubt is true.
Now I understand that 5GHz WiFi is for computers (gadgets with CPU and RAM) and 2.4GHz WiFi is for appliances such as printers, security cameras, smart hubs and so on.
Both signals are equally important.
