Why is WIFI_SSID needed? #157

wewa00 commented 5 years ago

"--wifi-ssid WIFI_SSID The ESSID of the WiFi network the device should eventually connect to."

I actually don't see any reason why the Sonoff device should need connect to the home WIFI. Which eventuality is meant here?

That's how the Sonoff downloads the new firmware, SonOTA tells the Sonoff "connect to this WiFi, and download updates from here" (where here is a web server running on your PC).

Ok, I thought for that the ITEAD-* network is used.

Are the different files (image_user1-0x01000.bin, ...) downloaded using different networks?
