I have a pretty decent home automation setup going for the last 5 years at this place with no issues using the hue ecosystem till my hue bridge died last month. Motion battery free buttons and timers for lights and outlets.

Have now made the jump to HA so we will see how long it can go post setup without falling over (and adding some things) but 5 years before the first issue (and so far I have some hue bulbs going on 10 years) is solid enough imho

So it can be done and is not always a lie.
