I have 3 on my boat. The units works perfectly on the local router, but because I have a wireless 5G connection (Peplink) as stated, it needs port forwarding, which is not achievable without a PhD in WiFi configuration. I found a workaround using an old Samsung tablet running 24/7 on the boat operating the EasyTouch software and remote access software to the tablet called "AirMirror" on the on boat tablet and my cellphone. Kludgey, but it works and gives me off-boat access and control via 4G/5G and Marina wi-fi without port forwarding. In today's world, where my on-board CCTV cameras, my Victron power system remote, my water sensors and my Nest all provide remote control WITHOUT port forwarding, this situation is inexcusable. This is easily solved by MicroAir re-writing updated software on the MicroAir EasyTouch for Marine. A major shortfall and very disappointing for an otherwise good product.
