New instructions updated June 12, 2024 for installing Tilt Pi on Raspberry Pi OS Bookworm released in May 2024. Feel free to contact us at info@baronbrew.com for feedback or any questions.

Using SSH from another computer or from the Raspberry Pi terminal, enter the following commands.
Step 1
Update Raspbian packages and install python install utility, "python3-distutils".
sudo apt-get update
sudo apt-get install python3-distutils
Step 2
Get the “aioblescan” bluetooth scanner module customized with Tilt plugin, unzip downloaded file, go to install folder, and install. Once you complete this step, you can run the command "sudo python3 -u -m aioblescan -T" to verify Tilt scanner is working. Make sure Tilt is nearby and floating if doing the test. Use "ctrl-c" to stop scanning.
wget https://github.com/baronbrew/aioblescan/archive/master.zip
unzip master.zip
cd aioblescan-master/
sudo -H python3 setup.py install
Step 3
Install node-red update script for Raspberry Pi using node-red version that works with Google Sheets web apps (this install script installs version 0.18.4 which allows following redirects of http POST requests).
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --confirm-pi --nodered-version="0.18.4" --node18Step 4
Install dashboard ui node v2.15.5 globally for node-red and enable auto-start of node-red at boot.
sudo -H npm install node-red-dashboard@2.15.5 -g
sudo systemctl enable nodered.service
Step 5
Reboot to start node-red on boot.
sudo reboot
Step 6
Download Tilt Pi app (node-red “flow”) that uses the Aioblescan module
wget -O /home/pi/flow.json https://raw.githubusercontent.com/baronbrew/TILTpi/Aioblescan/flow.json
Step 7
Run downloaded Tilt Pi app/flow in node-red:
curl -X POST http://localhost:1880/flows -H "Content-Type: application/json" -H "Node-RED-Deployment-Type: nodes" --data "@/home/pi/flow.json"
Step 8
In a web browser visit http://raspberrypi.local:1880/ui or http://localhost:1880/ui (if not using SSH to install). If this doesn't work, you may need to find the IP address of your Raspberry Pi and go to http://X.X.X.X:1880/ui where X.X.X.X is your Raspberry Pi's IP address.
