Does Sound & Light Machine require Wifi + password

I have a question regarding the Sound & Light. Does it also require Wi-Fi with password?
I purchased the Nanit camera and light and sound, thinking it would be easier to manage both products within one app. Unfortunately, I often have connectivity issues with either the camera or light/sound.

There cant be a security risks of using an open hotel Wi-Fi network for a light machine, right? Typically, hotels provide open Wi-Fi networks that require a name and room number for login, which I still cant use with any Nanit product. I cant use Nanit while traveling and the travel case seems to be a waste as well.
