Existing home has two low-voltage, lighting transformers, one ring, floodlight, one ring, doorbell and eero pro 6E Wi-Fi. Completed factory reset on one ring lighting transformer because it constantly said low signal and then disconnected from the hub. Deleted it and repeated process. It finally connected to the hub and we were able to control it. Then the next day it disconnected from the hub. Ring says there cannot be two lighting. Hubs in one home. And that the lighting hub needs to be in a centralized location. But each lighting transformer is more than 200 feet away from each other. The Wi-Fi signal outside is just as strong as inside, you can be two doors down and still be connected to the Wi-Fi. Apparently the ring hub is not on the Wi-Fi. It’s on a Bluetooth signal. The exterior of the home is Stucco.
