Hi! I’m new to home assistant and I’m wondering what would be worth the cost. A lot of the “smart” appliances seem overly expensive and automating them would only save me a handful of minutes each day. I live in canada where power is cheap, so things that save power aren’t particulary useful. A way to open/close the windows and doors sounds useful and would save me the most time, but costs thousands. A way to keep track of what is in the fridge and propose recipes to avoid food waste would be nice but I’m not entirely sure how I would setup such a system.
Does anyone have ideas of worthwhile things I could setup that would be worth the cost?

I think highest/easiest ROI would be devices that alert or avoid bad events.
- freezer/fridge temp monitors to avoid food going bad (circuit failure, door cracked open, part failure)
- water leak detectors (water heater, bathroom, sink)
- open door alarms ( garage door left open overnight, fence door left open that lets dog out)
- doorbell camera/microphone (unwanted visitors)
The only smart appliances I have ATM are smart light bulbs. These also partially contribute to saving energy (eg turn off lights when nobody is home / in the room), but even if that is not your priority, you can set up nice automations to soften the light as it becomes darker. I also use HA with Rhasspy to voice-control the lights.
As for fridge contents tracking, I wish there was a usable solution to what you describe. I have tried Grocy (can be integrated with HA), which looked nice, but I eventually stopped as it took a really long time to maintain. After each shopping, I had to input everything I bought (almost an hour usually). Then, each time you use something (eat a bun with some cheese, finish a bottle of milk, open a new sachet of some seasoning, etc), you must ‘consume’ it in Grocy. 99% of the time I forgot or was too lazy (once again, it just takes too much effort) and therefore the stock database was always out of date, making the whole thing useless.
Other things: I haven’t tried yet, but I also want to acquire some cheap sensors for temperature, and perhaps other things that I can’t think of right now. Maybe turn on the AC for a bit when it gets too warm (and somebody is in the room)?
Personally, that isn’t how I think about a smart home system. There isn’t a need to do major changes until maybe you need to get it replaced anyways. Starting with things like lights, a few shades, door sensors, are good ways to start. The biggest question is what do you want to get out of it?
Doing temperature monitoring in each room of the house. It really lets you work out where you’re losing heat, or failing to cool in the summer, and keep things more comfortable.
I bought a 5 pack of xiaomi temp sensors from Ali express… They were like $5 each? They’re Bluetooth but you can bridge to HA using an esp32 with esphome. Really cheap way to get some resolution on how and where and when the house is heating/cooling.
I was surprised at how poorly I understood how to manage the temp of my home. Knowing really is half the battle.
