Well the Remote Station (IP) is never intended to be used with secure port, because it’s generally used for controllers on the same network. In this case it’s usually not necessary to use secure connection unless if you are worries someone is logged onto your network and sniffing traffic (which would seem a bigger issue if they managed to get your WiFi password).
If the master and remote controllers are not on the same network, the Remote Station (OTC) type would be more appropriate as it goes through the secure cloud server — that is intended for controllers NOT on the same network hence secure connection is necessary.
