Sure. I don’t have many enabled right now but some that I’ve used that are probably useful to others
I have a zigbee smart lock that was relatively cheap but didn’t have a sensor on it to detect if the door is open or closed, just a timer built in. To make the lock smarter so that it won’t attempt to lock if the door is open, I’ve used a $10 aqara sensors to detect if the door is opened or not and then combined those with the door lock to say, trigger a door lock after 5 minutes of the sensory closing, but only if the door isn’t opened again.
Another Aqara sensor automation that I don’t use any more as we moved to a house that has a carport rather than garage, but I used a contact sensor on my ‘dumb’ garage door to detect if the door was open or not. If the garage door was opened, the garage light would go on. Could do this other ways such as with motion sensors etc but unlike a motion sensor this would keep a light on until the door closed.
I have a robotic vacuum that I would automatically turn on when every person left the house. If someone was detected returning within a KM of the home, the robot would then return to the dock so it was out of the way when people got home. I really really loved this automation, but I haven’t used it since having kids 4 years ago as there has inevitably been too many toys etc that the vacuum would pick up now days. If your floor is relatively tidy but, it’s a great way to do a vacuum.
I haven’t explored it yet but Home Assistant pulls in my data from my solar panels and battery. In theory I could probably automate some of my appliances based on power generation or battery charge. Haven’t explored that fully yet however.
Those are some thoughts. Right now I use it mostly to bridge devices that otherwise don’t talk together or integrate with HomeKit. Haven’t played around with the automations for a bit, but meaning to go in and have a play with it more at some point. It’s a product I tinker with for a few weeks then let simmer for months before coming back too.
Thanks for the ideas! I really like the third one
Where would one find these sensors? And, are they supported by the vendor for a decent amount of time?
Anytime I've tried finding door-open sensors in this price range, I can never find brands that seem well known and reputable (thinking of vendor updates), or that won't take two months to ship to my place. Or is that just the trade off for the price?

Usually grab them on sale. Also a few others from the Aqara family such as climate (humidity and temperature) that you can get cheap. Have a motion sensory from them too that works ok but i don’t currently have in use.
I combine these with a Conbee II and in home assistant I use ZHA (over deConz, which is an option too) to manage connectivity to the sensors. I don’t use the Aqara hub any more as I’d rather run things locally via home assistant than using a third party hub which removes any potential concern around privacy. I’m honestly not sure if these sensors are upgradable or not but they work reasonably enough. Maybe once every 6 months I need to spend 2 minutes reconnecting one but it’s not too common. It helps to have some ZigBee smart power plugs scattered throughout the house, even if you aren’t automating power to things, as they form a mesh network which can make battery powered sensors more reliable.
I picked ZHA over deConz largely in the basis it’s development was linked to home assistant so I figured over time it’d see more development from the home assistant devs.
I aim to use ZigBee where I can over WiFi or Bluetooth devices. Lower power and more responsive in my experience. Also frees up the wifi traffic and the more ZigBee things you add the more reliable the mesh network gets.
Thanks for the great response! Especially about the Conbee II and ZHA pieces. I'm slowly piecing things together for my first wave of home automation, and this will definitely help with the analysis-paralysis I'll hit along the way!
