I have 2 Samsung TVs:

Samsung QE75Q70R i stuen

Samsung UE43AU7105KXXC i soveværelset.

In general I would like both in Home Assistent, but there are a number of integrations:

Built-in Samsung TV Integration

https://www.home-assistant.io/integrations/samsungtv/

• Finds both TVs
• Gives a constant approval dialog on the Samsung QE75Q70R 

Samsung Smart TV (custom_component/samsungtv_tizen)

https://github.com/jaruba/ha-samsungtv-tizen

• I never see this in the "Integration" section
• Seems to work with configuration.yaml entry
• Seems to wotk work 2 TV's with configuration.yaml entries.
• Limited attribute feedback

SamsungTV Smart (custom_component/samsungtv_smart)

https://github.com/ollo69/ha-samsungtv-smart

• Only useable with one TV
• Exposes a lot of TV attributes
•
