About LocalThings
LocalThings is a free, open-source integration that lets Home Assistant control Samsung smart appliances over your local network, with no SmartThings account. After setup, the integration never contacts Samsung's servers. It speaks the standards the appliances implement themselves (OCF over encrypted CoAP) and turns each one into a normal Home Assistant device with controls and sensors.
Setup is deliberately small: install from the default HACS list, restart Home Assistant, and enter the appliance's IP address. LocalThings detects the type and model and creates the matching entities automatically. The appliance keeps its own connection to Samsung; LocalThings changes how you talk to the machine, not what the machine does on its own.
It runs wherever Home Assistant runs: Home Assistant OS or Container on Linux, and Home Assistant OS in a virtual machine on macOS or Windows, per the official installation docs. Most Samsung appliances from about 2022 onward are supported, plus some older washers, air conditioners and wall ovens through a legacy interface. Development is active (version 0.36.0, November 2026) and new models are added from community diagnostics downloads.

Frequently Asked Questions
Does LocalThings need a SmartThings account?
No. It talks to appliances directly over your local network. It contacts Samsung's servers once, without any login, when you add your first appliance, to read a public identifier; later appliances need no internet at all.
Will it cut my appliance off from Samsung?
No. The appliance keeps its own connection to Samsung; LocalThings only removes the cloud from your control path. Keep appliances registered in SmartThings: removing one makes it reset its network settings and drop off Wi-Fi.
Which appliances are supported?
Most Samsung smart appliances from about 2022 onward: washers, dryers, fridges, air conditioners, ovens, cooktops, dishwashers, microwaves, robot vacuums, soundbars and more. Some 2018-2022 models work through a legacy interface, and missing capabilities can be added from a diagnostics download.
