Smart Thermometers and Smart Cameras that work with HA (bought from AMAZON)


Apologies if this topic finds itself in the wrong category .

I use Amazon all the time and I’m trying to find some smart thermometers and security cameras that work along side HA? I currently have Hive working well in HA but I also would like to have a thermometer in each room and displayed on my dashboard but I am struggling to find one that is simple to set up in HA. I don’t mind a little configuration but nothing too heavy.
For your information I am using HA core-2021.9.7

Thanks for taking the time to read this and hopefully give me any advice!
