Merge 2 Homes in HomeKit?

Could not add many smart devices after migrating to new ISP w new router(s). Kept WiFi Network name & password, which made set up for half my devices a breeze. Other half have been a nightmare. Eero Pro 6E does not have a HomeKit choice at the bottom of the Settings screen as their help page states. One desperate suggestion said to create a new Home in HomeKit app. Miraculously, I was able to add remaining devices, but now have two separate "Homes". Though they are on the same WiFi network, the "Test Home" items have "No Remote Access" & require manual interactions on their separate "Test Home" section of HomeKit. No Siri & lots of redundant, manual switching on the app. One notice said "Router name is not the same as your WiFi network name (also known as SSID). Use third party app to change your WiFi network name." Of course, that would eliminate all my first-try device connections. I just want to combine the two Homes as one.
