After burning the image create an empty file called ssh in the boot folder of the SD card. To start, you should know how to SSH to the Raspberry Pi and also use the remote connection VNC. To obtain a Free API key go to and register.ĭownload the full raspbian buster image and burn to a 8GB or bigger SD card. The touch feature of the screen is not required but is helpful to shutdown the App. The screen required is a 3.5” HDMI or a 5". The inside temperature is obtained with a DHT22 sensor connected to the Pi.
It also requires a FREE API key from openweathermap for operation. The script requires the Longitude and Latitude coordinates for your location. This project uses the openweathermap API for weather information. Longer term I’d like to write a single program to replace the script and Curl, but thought Curl and shell scripts would get things going faster.Raspberry pi openweather display. I was planning to write a shell script to periodically invoke Curl to query TTN for new data, call the JSON parsing program to retrieve parameters from the JSON file, format a message with new data to send to Weather Underground, and invoke Curl again to post the message to Weather Undergroud. I’m planning to parse the JSON file returned from TTN, then post the data to my page on Weather Underground again using Curl. I’m using Curl to request the data from TTN and store it in a file (JSON). The node and gateway are sending data to TTN and I’ve created a storage integration on TTN that allows me to query the data from the node. I’m using an Arduino and Dragino Arduino shield at the weather station and a Raspberry Pi with Dragino hat as the gateway. I thought I would try to do this with LoRa. I’d like to get data wirelessly from a small home-made weather station to Weather Underground for display. I’m new to TTN and LoRaWAN and am wondering if I’m misunderstanding how to use TTN and LoRaWAN.
