Overview

Weather Clock for Raspberry PI

This project is a dashboard for Raspberry Pi to display environmental weather data, rain radar, weather forecast, etc. on a connected LCD written in Python. The data is collected from local MQTT broker and also from Internet services.

Display

I used a 7inch IPS display with 1024x600 hardware resolution and HDMI input, which has a low power consumption of only 1-2 Watt which is predestinated for 24/7 operation. An RCWL-0516 doppler radar microwave motion sensor module is used to switch off the backlight when no motion has been detected for the last 10 minutes. This is for saving energy when nobody is in the room to watch the dashboard. The backlight is switched on automatically when motion is detected.

Raspberry PI

I use the Raspberry Pi Zero WH which has enough performance, a low power consumption and an HDMI connector. Also it is possible to connect it directly to the backside of the Waveshare display. Only a mini-HDMI (type C) to normal-HDMI (type A) cable is required. The whole system (RPI + display) can be powered over the USB connector and consumes in total a maximum of 4 Watt.

Software on the Raspberry PI

Use a 16Gbyte SD card and install Raspberry Pi OS on it
Configure graphics driver and resolution as described on https://www.waveshare.com/wiki/7inch_HDMI_LCD
Configure a static IP within your WiFi network
Activate SSH for remote configuration, SW update and maintainance

Install following packages used by the Python program:

pip install python3-utils
sudo apt-get install python3-pil python3-pil.imagetk
sudo apt-get install python3-pip -y
sudo pip3 install paho-mqtt

Weather Clock configuration

Please change following variables according to your location. The value for xmin and ymin can be determined with https://oms.wff.ch/calc.htm for a specific zoom level.

longitude = "8.900"
latiude = "48.800"
timezone = "Europe/Berlin"
zoom = 12
xmin = 2148
ymin = 1409

Please change following variables according to your MQTT settings:

mqtt_user = "*********"
mqtt_password = "***************"
mqtt_broker_address = "192.168.xxx.xxx"
mqtt_port = 1883
mqtt_topic_pressure = "/483fdabaceba/pressure"
mqtt_topic_outtemperature = "/483fdabaceba/temperature"
mqtt_topic_outhumidity = "/483fdabaceba/humidity"
mqtt_topic_intemperature = "/483fdabaceba/temperature"
mqtt_topic_inhumidity = "/483fdabaceba/humidity"

Internet services used
