IP Gateway for Automatic Home or Building HVAC System

The IP gateway is an optional bridge to an Intranet or the Internet for all sensor and/or control data. HTTPS or MQTT (among other options) can be used for secure protocol requirements. Multiple PHYs could also be used, such as:​

  • Wi-Fi based on IEEE 802.11​
  • Thread, Zigbee or 6LoWPAN based on IEEE 802.15.4​
  • Ethernet based on IEEE 802.3​
  • LTE-M/-NB (depending on the geographical region and available providers)​
  • LoRaWAN​

System Benefits

  • Bluetooth® 5 mesh communication enables communication with other sensors and the actuators.
  • The IP gateway function could either be a separate device or integrated in the actuator(s).
  • For the power supply, usually mains will be needed for the fan/HVAC (e.g., 230Vac or 110Vac, or 24Vdc) from the building control system. Renesas has a comprehensive set of power solutions available, depending on the exact use case.
