Structural analysis of the Meross MSG100 Remote identifies it as an ESP8266-based Wi-Fi relay designed for digital-to-analog signal bridging. The unit operates by providing a dry-contact closure, making it technically agnostic to the proprietary protocols of most legacy garage motors. Material specifications include a hardwired reed switch for physical door position verification, which avoids the false positive readings common in accelerometer-based sensors.
Performance metrics indicate the device is a mature hardware platform utilizing a MediaTek or Espressif chipset for 2.4GHz stack management. Hardware limitations include a lack of 5GHz support and a requirement for the RGT02 accessory when interfacing with encrypted Security+ 2.0 systems. Operational data indicates that local control is maintained via the HomeKit protocol on supported hardware revisions.
Functional features include:
- Signal Type: Dry-contact relay.
- Power: External 5V input.
- Sensor: Wired magnetic reed switch.
For high-traffic environments where wire management is a concern, the myQ Smart Garage Door Keypad with Camera provides a wireless alternative with integrated visual monitoring.
This unit is classified under smart bridge devices, specifically for analog-to-digital relay conversion.
