I’ve started only buying smart devices if there’s already an active community project to provide firmware and such should the company disappear or give up. If you want the convenience of “smart” devices, you have to compromise somewhere.

You can also buy devices that use open protocols like zwave, zigbee, or thread/matter. zwave is by far the best of the 3 because the certification requires that the devices properly implement the standard so any controller can manage any device, however that also makes it the most expensive and least flexible of the 3. For me stuff I care about long-term support for is zwave (thermostat, living room lights including wall controller), stuff that I'm less worried about having to possibly replace some day like motion detection or smart outlets can be zigbee, or Matter. Thread/Matter is starting to get to the point where the standard and interoperability testing is robust enough that I might consider it for my mission critical stuff in the near future.

As far as music, I've got 20 year old speakers hooked up to a 10 year old receiver that gets fed by the TV or anything plugged into it, thanks to HDMI ARC I don't have to worry about what TV I use or what device is plugged into it, downside of course is that the TV has to be turned on and tuned to the music source (not a big deal for my personal situation, others may not like the compromise).
