Is there a good Android app that helps manage a smart thermostat system with room sensors?

ecobee is an Android app designed for controlling ecobee smart thermostats and their accompanying room sensors from a mobile device. For users seeking to manage home temperature with a multi-room approach, this app provides core functionality like remote access via Wi-Fi, allowing adjustments from anywhere. Specific features include room sensor integration, which monitors temperatures in different areas to optimize comfort, and a GeoFence option that automatically switches to away mode based on location. In real-world scenarios, such as balancing heat in a two-story home or pre-cooling before arrival, the sensor data helps tailor settings. However, reviews indicate that GeoFence can be inconsistent, sometimes displaying distances in meters instead of miles or overriding manual holds with EcoPlus modes. The app is praised for its straightforward setup, with former Nest users noting a smooth transition; connecting involves selecting a network and entering a password. Daily use includes a temperature wheel for adjustments, though some report it selecting unintended numbers after touch. Limitations include self-hosted ads that can clutter the interface and persistent notifications for reconnected sensors, which block app access until dismissed. Despite these flaws, the app maintains reliability for basic remote control and sensor management, making it a viable choice for ecobee hardware owners who prioritize convenience over polish.
