smartNode

The smartNode smart device is very similar to the smartWiFi and the smartBLE, except it relies on Node-RED as broker and front-end instead of Blynk.

Node-RED offers a flexible environment to acquire and process data, design and display a dashboard, and send commands. 

Node-RED runs on any computer and even on an Android-powered tablet. The dashboard only requires an internet browser, on the same computer or on a different one. The responsive design of the dashboard makes it suitable for any screen size.

The device connects to the I²C port of the RoboTX and is powered by the RoboTX.

Connectivity

Selecting the radio is no longer a criteria, as any radio protocol can be used, among WiFi, Bluetooth, BLE or sub-1 GHz to name a few. ​

Node-RED includes nodes for MQTT and Serial connectivity, but is extensible with additional nodes. 
​
In case of MQTT, the same terminal where Node-RED runs also hosts the MQTT broker. 

​​Finalised and Working Device

The device in encased inside the standard 9 x 3 cm red box with the I²C ribbon cable connected to the RobotTX.
