There is a list of devices that are natively supported by the HE hub and then others rely on Community developed integrations normally. Hopefully someone else can get you the link to the compatible devices list. (bit hard on my phone)...
I probably got a little over enthusiastic, as I don't have any real experience with the devices you listed.... In terms of your AV equipment, how do you control them? Do you use anything like a Harmony remote or similar smart remote system?
The Tuya stuff you should investigate more, you may need to go via IFTTT or flash the firmware if you can, I'm not sure.
