- must not add insane amounts of cost to my power bill
- Has to be upgradable if I need to add upgrades to the hardware in the future
- Has a speaker
- may want to possibly also set up node red but it depends on if I need it or not because I may just be fine with home assistants automation
- has to have wireless connectivity
- mainly setting this up to add automation around my reolink cameras linked through the reolink home hub for example getting a second camera in the same area to start recording when one detects motion or link other smart home security products like sirens or floodlights
Any reason not to just buy a Home Assistant Green?

Edit
I just saw that you want something upgradable.
