What are the differences between H1 (device with antenna) and H2 (pluggable device)? ============================================================================================================== 1. Networking Method - H1 supports two networking methods: connecting to a 2.4 GHz wireless Wi-Fi network and using Ethernet. On the other hand, H2 only supports connecting to a 2.4 GHz wireless Wi-Fi network. 2. Power Supply - H1 requires a dedicated 5V/1A power adapter for power supply, while H2 can be directly plugged into a power socket and can also be used to control the power socket switch, offering a wider range of application scenarios. 3. Compatibility - H1 is compatible with all MOCREO Sensors except for the Local Sensor (ST7/ST8). On the other hand, H2 is only compatible with ST5/ST6/ST9/ST10 Sensors (wireless sensors based on BLE wireless communication technology).
