This is an edited answer and review. I bought five of these because we have a lot of decks, landscape lighting, and water features on different trails. We have a nested mesh system and a strong, stable WiFi signal for the two I've set up so far. One of these devices kept falling out of the installation. But after the third adjustment it has been working fine for a week now. There was no Wi-Fi signal. It may be a mystery that will never be solved, but it works well now and I didn't want my harsh assessment of previous failures to persist. The other, away from his father, worked flawlessly from the start.
