In the database entry click on the pencil icon to open the second screen shown below. The sqlite node requires little configuration, just add the node to the canvas and open the configuration. That’s all that’s required outside of Node-RED, our database is ready for data! Using Node-RED with SQLite Our table is very simple and just has four fields, location, temperature, humidity and timestamp. create table sensordata (location text, temp float, humidity float, timestamp integer) Now your in the sqlite3 command prompt so we can go ahead and create a table for our data. First open a terminal, create the directory and then a database, mine is called sensors in /mnt/hdd/sqlite/ $ mkdir /mnt/hdd/sqlite/

I use the command line to create a database for our sensor data as it’s very easy and requires no extra install. To install the SQLite node in Node-RED follow these instructions. If you need to do this consider PostgreSQL or MySQL.

The one major downside to consider with SQLite is that it’s a file based database meaning that you won’t be able to access the data from your LAN or the internet (at least it’s not recommended). All are readily available to install and reasonably easy to set up but for our data SQLite stands out as being by far the easiest to set up and administer. Three choices spring to mind that could work equally well on a small device with limited computing power, SQLite, MySQL and PostgreSQL. You can read this post to learn how to mount an external drive in Linux. For this reason I mounted an external USB drive to the Pi and create the SQLite database on the external drive. If you intend to use a Raspberry Pi as I have done then I wouldn’t recommend setting the database up on the SD card as the read-write traffic can easily wear out the card prematurely. We need a database to store and query the data. This configuration report for the Cisco Unified CallManager cluster has the following details:ģ.1.Now that my sensors are successfully collecting data and the data is being processed by a Node-RED flow on my Raspberry Pi the final step is to add some persistence to the data.Īs it stands the data is constantly streaming and being displayed on a dashboard but after that it’s discarded so there’s no way to see the min or max temperature for say the last 24 hours. It shows first the comparision statistics as sub-chapter, followed by the object differences. This chapter contains the differences for each object that has been found in the base and revised report.
