I am not a tech guy but like automation and since 2017 have accumulated the following:
(a) Two Tinxy 6 channel relay to control 12 points - lights and fan
(b) Three Sonoff 4 channel relays to control 12 points like above, 4-5 Sonoff single relays - the first automation I bought way back in 2016/17
(c) 5 Echo dots and 3 Google smart speaker and two 5 inch echo show
(d) An Amazon fire HD 10 in show mode which acts like a 10 inch amazon show on the cheap
(e) 2 smart plus
(f) Plenty of smart bulbs - Yee bulb, wipro bulbs during amazon sale, chinese bulbs
(g) Smart LED strips from US - you get 100 feet for 25 usd
(h) Halonix radar motion sensor bulb
Here is the smartness I have in my house which is my parents independent house with a garden in Bangalore
(a) I have garden streetlight types - 10 of them - they turn on at 6.30 PM and turn off at 9.00 PM thanks to Alexa and also sonoff ewelink schedules
(b) I have four outside light points with halonix radar bulb which are on during night times - turn on and off on schedule like above - so that during night time whenever we walk around they light up for few seconds
(c) Turn on and off lights and fan using Alexa. since it has been 3-4 years now, even my nearly 80 year old mom relies mostly on voice commands to turn on and off
(d) Using a free functionality found on youtube to turn on my desktop with alexa command. Turning off using alexa is a paid thing though which I didnt take
(e) Smart LED strip controlled by Alexa - turn off/on, schedulers, dimming, changing colors....etc
I have watched several videos on home assistant...but wonder whether I need one since I trust Alexa for most of my needs and they work well all the time.
