Sensebender Gateway

created by tbowmo , updated

The MySensors Sensebender Gateway is a compact Arduino Zero compatible board that is purpose-built by the MySensors team to serve as a fully-functional, high-performance MySensors gateway.

The MySensors gateway is the first device you will need for your MySensors network and this one is designed from the ground up for both novices and experts. The gateway supports the nRF24L01+ or RFM69 radios and can interface with a wide array of HA controllers via USB or Ethernet.

If you want to get up and running quickly with a no-compromise and flexible gateway designed and supported by the MySensors Team, then this is the gateway for you.

Features

High Performance MCU

At it’s core, the Gateway is equipped with a high-performance Atmel SAMD21 MCU running at 48MHz offering plenty of headroom for advanced gateway-specific features as the MySensors ecosystem expands. The SAMD21 MCU product line is Atmel’s ARM Cortex offering equipped with 32Kb of RAM and 256Kb for flash providing ample working and persistent storage for current and future gateway tasks.

Broad Home Automation Controller Support

The Gateway is compatible with more than 20 of the most common home automation controllers on the market using either USB or Ethernet. Literally all requested automation controllers are currently supported and the list continues to expand… Don’t see yours, it is easy to write an adapter and we are here to help you.

Secure IoT Radio Network

The Gateway includes footprints/pads for two very common radios supported by MySensors; the Nordic nRF24L01+ radio or the Hope RF RFM69HCW radio offering users different options for their locale/home construction and IoT projects. Each Gateway includes an ATSHA204 CryptoAuthentication chip that can be used for hardware-based message signing for secure radio communications, after personalisation.

Expandability The Gateway also includes an MYSX 2.6 connector that breaks out plenty of IO pins for DIY shields that can be used to add sensors and actuators to the gateway or to use the gateway board as a compact, high-performance node for more demanding IoT projects and applications. In addition, the Gateway includes a micro-sd card reader for IoT applications where additional local non-volatile storage is required (e.g. configuration files, storing time-series sensor readings for offline analysis, etc.).
