Here is HCA in action. LG appliances in SmartThings:
This looks really positive. I can’t see much detail on what devices will be included though - is it new appliances only or will older smart appliances also be included? What type of devices would be included (e.g. TVs?)
Either way, definitely a positive step! 
In the industry, televisions are not in the “appliances” category, smart or not.
In the US, appliances are refrigerators, stoves, dishwashers, washers, dryers, and some other large mains powered household convenience items.
Vacuums also count in this category in most countries.
From one definition:
Appliances are generally considered to be an individual piece of equipment for use in the home in the performance of domestic chores . By this definition, a dishwasher, refrigerator or stove would be considered appliances, but a water heater or a toilet would not.
That said, the new organization, the home connectivity alliance, intends to cover televisions and heating systems, as well as appliances:
The Home Connectivity Alliance’s HCA Interface Specification 1.0 leverages existing industry standards to define C2C interoperability and ensures that long-life appliances, HVAC systems and TVs are seamlessly interoperable with each other, regardless of manufacturer.
So this organization will handle televisions and appliances, not televisions as appliances. I know, nitpicky: it’s an engineering thing. 
From their press release for their new appliances standard (note that this standard does not apply to televisions):
Cognizant that the class of appliances HCA member companies manufacture are very expensive and can last for many years, the organization designed its standard so that legacy smart appliances can be upgraded to the standard via firmware updates—consumers won’t need to replace products they might have purchased just in the past few years. Choi emphasized that HCA’s standard is designed to complement rather than compete with the Matter standard that launched late last year.
So their intention for smart washers, dryers, and stoves is that you can update the one you already have, not have to buy a new one.
They are not making the same promise for smart televisions, though.
Very interesting and sounds very promising for the industry! Looking forward to seeing this
Was there an approximate date given for the integration with smartthibgs? I have a few smart GE appliances that I would love to be integrated.
A new Energy Management Interface from the Home Connectivity Alliance aims to streamline the process of connecting large appliances to the smart grid.
