I want to set up a wifi door lock in a house without access to the internet. This is for a home that is for sale and the owners do not live in the home and therefore do not have internet. If a buyer wants to look at the home, I can give them an access code. Of course my mind is racing with all the things you can do in the home when the buyers are looking, but I need to solve the first problem… how to get remote access!
I bought this hardware a netgear 4g lte modem (unlocked) and a tp-link wifi router. I will be using a raspberry pi 3. I know the door lock will have its own app, but I do plan to control lights and cameras later. I was planning to use a t-mobile sim card.
My enthusiasm has soured after reading a few posts about others trying to get a dedicated ip for 4g modems.
Any recommendations on service providers that might provide ipv4 addresses so I can use duckdns to access HA remotely?
or
Will nabu casa work?
I bought a netgear 4g modem and a wireless router.
I bought a t-mobile sim card to use in the modem.
I bought a raspPI 4, running hassio, and connected to the router
I found that sim cards only allow for one way data access when used for personal phones. I called t-mobile support requesting a static IP… they had no idea what a static IP was… After a long conversation with a few techs, they finally understood what I needed.
tmobile offers a business account for the sim card. The business account has a static IP.
They switched to a business account and immediatly the speed increased to about 40mbps and the ip was reachable from the internet (static IP). business account costs about $25 extra per month.
