Simple IoT Telegram Notifications & Commanding, Node-RED & Telegram Integration

This video walks you through how to interact with a Telegram bot using Node-RED. We create a simple flow to send an alert to the user if a sensor has not been heard from in a while as well as creating an interactive keyboard to allow the user to request different available sensor data values. These data values are pulled from an InfluxDB database using a query. Telegram is a free and open source instant messaging application. We used our IoT server video as a baseline for this project but it should work for any Node-RED instance you have running. The baseline system consists of a series of sensor nodes that send sensor data in a JSON message over a WiFi network to a Raspberry Pi via MQTT. NodeRED subscribes to the MQTT topic, interprets the json message data and then send the data to a database to be stored and used. InfluxDB stores all the sensor data. Then a Graphana front end will query the database in order to display the data we want to see and do a whole host of other things.
