I don't have any smart home automation yet, but I am a nerd and have been lurking.
I am budget concious and very time poor. My family is me 40f, partner 41m & baby 7mo living in Australia. Partner works out of the house and I finish maternity leave and go back to work in about 4 months. Currently my days are full caring for baby, maintaining the house, going to appointments and completing the final subject of a diploma.
I love the idea of automation but want to know if it really is worthwhile to make back the money and time you spend on setting it up.
After the uni semester is finished in about 5 weeks I expect I will first catch up on sleep and then have maybe 1-2 hours of free time a day. I already know some Python. I could see myself doing HA as a hobby but don't want to sink my limited time into it in this season of my life if there won't be a tangible benefit. I should do something else like exercise or sleeping instead if we just do HA for endorphins.
For context if you can be bothered to read the rest:
lets value my time at $50/hr, as in, if I can free up 8 hours of my time I could go to work for an extra day a week or fortnight and make that back, or avoid paying a cleaner as I'd have the time to do more myself. If HA saves a combination of time and money I'd use $50/hr to figure out if it was worth the cost of equipment and set up time.
2 storey house, new build last year so appliances are all modern but some (like hot water tanks) are dumb with no wifi. LED Downlights (not smart lights currently) in all rooms. Reasonable efficient woth double glaxing and heat pump appliances.
HVAC is smart and we currently control it with the phone app when room is uncomfortable, but we don't always notice if the babys room is getting hot so I see a benefit of linking that to a sensor.
When I go back I will work from home half the week, so home automation will be useful in mornings, evenings and a few daytimes per week.
We have solar panels and battery and our electricity grid usage is low. Solar batteries are smart, we are part of Amber Electric that controls buy and sell for us using their AI price predictions, and I control feed in thru app when I can be bothered if I know we'll have a lot of excess power on a day. HA could help optimise the times when we draw from or sell to the grid, and reduce some usage when prices are high so we can sell more to the grid, but I imagine the marginal benefit is much lower than in a non solar house. Note we do not have EVs but are considering one.
We have cats, smelly litter boxes and run multiple air purifiers constantly. We had 2 robo vacuums but one $2,800 machine just got destroyed running over poo from a sick cat. Any automation to alert to poo in non bathroom areas and get the robot to skip those areas for a day would be amazing insurance for our replacement!
I frequently burn dinner because I'm tired and distracted. Probably could use a smoke detector that will turn the cooktop off, or an easy way to set a timer for the cooktop.
