Specifically I will be using the Dragino LHT65 temperature sensor. Node-Red is used to store the time series data to InfluxDB and then backed up on InterPlanetary File System (IPFS). I suggest you do the same unless you secure the device as detailed in the document mentioned above.This guide will provide detailed instructions on how to send Lorawan sensor data from Helium Network to a Raspberry Pi (or VPS) via MQTT. I use Telegram with a private bot for the few operations that I would do while not at home. My node-red is not exposed to the internet and I don't intend to. WindiskSD for windows or ApplePiBaker is what I use on Mac. Remove the // and insert your personal secret key.įinally shutdown your pi, take out the SD card and use your pc or Mac to make a backup. If you want to maintain these after you reboot you pi, best to set a user configured credentialSecret. Sometimes in your node-red configuration screens you will need to supply credentials. If you get errors check the dependencies or try sudo apt -fix-broken install node-red-contrib-huemagic (Philips Hue).node-red-contrib-simpletime (simple timer).These are your extensions you have loaded or where you install new ones. Node-red has some strange terminology I find, but on the hamburger menu on the right you'll find different options. sudo apt-get update sudo apt-get upgradeĪ basic UI appears. I use Termius as I'm on a Mac.įirst thing is to update the setup.
It should also show the host raspberrypi.local. Insert the card in the Raspberry and wait for about 2 to 3 minutes.Ĭheck your wifi router to find the IP of the new device. This will enable SSH when the raspberry boots. On a MAC you can open terminal and run: touch /Volumes/boot/ssh Then you need to add a blank file to the root called: ssh Replace country code with your country ISO code, SSID and password. Open it with a text editor and insert: ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=BE network= On a Mac open terminal and use: touch /Volumes/boot/wpa_nf If you want to find info about it search for 'raspberry headless'.Ĭreate a file in the root of the SD card. As the Raspberry 3A+ has Wifi only it needs a config file. When it's ready you need to prepare a few things before ejecting the card.
