[SOLVED] Mobile LAN that connects to home wifi?

[scuttlebutt]

I am considering wiring up my boat with smart switches for certain items. I'm likely going to use a Sonoff DIY smart switch. Ideally I'd like to be able to maintain a wireless LAN no matter where I travel so I can still control these items. One solution to this might be a 4G mobile router, however I need the LAN to work outside of cell service and when I get home I'd like the network to switch over to the wifi I have for free on the dock, thus saving any 4G data.

Any recommendations on network setups that could make this happen?

You can get a multi-wan router. One of those WAN links is your 4G. The other is your WIFI. You set the mult-wan router to fail to 4G when the WIFI is not functional. There are network systems tailored to ocean going vessels. They will use WIFI, 4G, satellite for world wide coverage.

I'm not super familiar with multi WAN routers. Can it have a wireless input or will I need a mesh router to connect to my dock wifi to then an Ethernet connection to the multi WAN? Then another wifi router downstream of the multi WAN to create a wireless LAN on the boat?

I'm not sure if I'm making sense as networking is not my square as you can probably tell

You can mount a outdoor wireless device on the boat. That outdoor device would be ethernet connected to the multi-wan router. A boat moves around. I don't know how much that movement will impact your wireless link. It will depend on the distance and signal strength.
