I have a lot of smart devices in my home, light bulbs, nest thermostat, echo devices (Amazon Alexa), garage door opener, etc. The last time I changed to a new internet service provider, it was a real pain having to set up each individual smart device on the new wireless router belonging to the new service provider.
Looking ahead, I would like to avoid that next time. I'm wondering if I could get a wireless router/range extender/something to which I could have all of my smart devices wirelessly connected, and have the wireless router/range extender/?? connect to the internet service provider's router. My hope being that I could change to the new service provider's router just one time in one place. Is that possible? What would I need to buy?
Note: I have smart devices all over my two-story house and even in the garage, so there is a whole house to cover.
