This database was created out of frustration trying to locate a Raspberry Pi product in the height of the chip and supply chain shortages of 2021. It's a website to track Raspberry Pi 4 model B, Compute Module 4, Pi Zero 2 W, and Pico availability across multiple retailers in different countries. I ideally did not want to spend and money but it could have been worse.Yesterday André Costa emailed me about his new website, rpilocator. "+hdmi+ips+lcd+display+kit+for+raspberry+pi&cfm=true&pm=true Remove X Org X Server Output sudo nano ~/.bash_profileįinally I needed a display without OSD popups which I found here: Remove autologin message by modify autologin service sudo nano second line with ExecStart=-/sbin/agetty -skip-login -noclear -noissue -login-options "-f pi" %I $TERM Remove Raspberry Pi logo and blinking cursor sudo nano /boot/cmdline.txtĪnd add logo.nologo vt.global_cursor_default=0 Remove Rainbow Screen sudo nano /boot/config.txt I have removed the raspberry pi messages as follows: One of my main issues was the on screen messages that looked unprofessional. I have used the guide above but instead of turning just the screen off I have used a relay to control power to both the screen and the raspberry pi. I have found a way of turning the power off to the screen and the raspberry pi and starting with a nice clean black screen until the website opens. This is more of a guide for me to save energy but hopefully someone will find it useful. Tabcontent = document.getElementsB圜lassName("tabcontent") * Create an active/current tablink class */ * Change background color of buttons on hover */ My html coding skills are very basic too but it’s quite simple, Chromium starts with this html file: To do this I needed a way to control the screens via home assistant. This way the screen is always on in the room I am in but I will never seen the panel switch on or off. I come home -> all screens turn on -> I enter the Kitchen -> motion detected in the kitchen screen stays on and all other screens go off in other rooms after 5 mins -> enter Living room via hall -> all screens on when I am in the hall -> living room stays on all others off -> etc. Therefore as each room is accessed via the hall I would switch all screens on when motion is detected in the hall and would switch off individual screens when there is no motion in each room for 5 mins. My long term plan would be to have one in every room I think it would look a bit “unprofessional” if we see these on screen messages when the screen switches on or off. Another screen has “hdmi 1” when it comes on. When the screen goes off it has an on screen display that pops up that says “screen powered off” then “power saving mode”. I found it easier to push everything to a variable then pass the variable to MQTT. The simple command I use inside my script to call the routine in my script: MQTT("docker/ContRun",Dock_MQTT) In Python3 I get errors if I try to pass I think becuase it is the default. I don’t use the Port in this script since this one is Python3 but in my Python2 scripts I have to pass it. I like to add a debug option to all my scripts so I can easily turn on and off printing to screen.īroker_IP = "10.74.1.224" # MQTT Broker IP # Prevent crashing if Broker is disconnected Print ("MQTT Publish Complete for " + MQ_Topic) Mqttc.publish(MQ_Topic, MQ_Payload, retain = True) My MQTT() routine: def MQTT(MQ_Topic,MQ_Payload): I then added the following to my configuration.yaml:Īll of this gives me a screen I can turn on and off from home assistant.

KIOSK_URL can be to your Lovelace or in my case it is to my TileBoard - New dashboard for Homeassistant I created a raspberry pi in kiosk mode based on these instructions: The basis for the control screen is a raspberry pi with touchscreen that was donated to me. I have been trying to create a room control screen so that I can control the smart elements of each of my rooms.
