So, we moved from the big city out to the country, and for the first time in my life, I don't have internet at home. I know, it makes no sense, but nobody services our location (save for terrible satellite, Starlink with "Best Effort" option, or $80/mo for 2.5Mbps connection through landline phone company). While living in the city, I amassed a collection of smart devices and was so proud of my automations, but now I have to actually walk around the house turning off switches and locking doors behind the wife and toddler.
I have taken some small steps to bring the house into the 21st century, including setting up an offline LAN, bolstering my Plex Library, and connecting my Chromecasts to the wifi network in order to stream (thank God for the Disney Babysitter). I have purchased a Hubitat and it has been collecting dust waiting for me to configure some Z-Wave and Zigbee devices, and I'm finally able to get some of that done!
Here's the rub: The Hubitat (as well as Plex server) are all running on the LAN, non-internet wifi, and connecting to that network in order to do anything Plex/Hubitat-related will disallow cellular data. I have tried to configure the wifi settings on my Samsung to allow for both data sources, but to no avail.
Here's what I'm trying to do:
I want to be able to connect to the wifi on my phone/tablet to have access to my smart home and use presence automations, but also not constantly connect and disconnect to that network as that disables cellular data connection. I have searched high and low, even bit the bullet and called my Dad, but nothing! I remember having seen something about a similar situation on a forum, but I can't for the life of me remember where it was or how to word it. So, here I am, coming to the experts!
tl;dr: No home internet. Have Hubitat on LAN. Want to connect to LAN while maintaining cellular data connection.
