Collection of scripts for setting up home automation sensors, monitoring and control devices. Raspberry Pi acts as a hub and collects sensor data from numerous wireless ESP8266/ESP32 devices. Raspberry Pi has 4G connectivity and MQTT bridge forwards all collected messages to a remote server where they can be stored (InfluxDB) and visualized (Grafana).

Example files to copy to Raspberry Pi's boot partition in order to activate wireless network and ssh on the first boot.

Find out the correct IP address e.g. using arp -a command on a Mac and ssh to the server with default user (pi/raspberry). Change password and copy your ssh public key into .ssh/authorized_keys. Now you are ready to execute Ansible playbooks.

More about setting up headless Raspberry Pi

pip3 install ansible

Add your hosts into /etc/ansible/hosts

[raspberrypi]
rpi
[raspberrypi:vars]
ansible_python_interpreter=/usr/bin/python3

Execute playbooks

cd playbooks
cp common.yml.{template,}
ansible-playbook setup.yml

Basic setup of Raspberry Pi 4b.

Configure Huawei E392 4G dongle. inet_down.sh script tries to fix broken internet and/or reboot in case ifup/down didn't fix the connection.

Setup a MQTT broker which gathers observations from connected sensors and other wireless devices on the local network.

Raspberry Pi is wired with BME280 temperature, humidity and pressure sensor. The sensor is read once per minute bme280mqtt.py and values are sent in a MQTT message.

Outside temperature is polled using the FMI Open data WFS service.

Establish Wireguard VPN tunnel to a remote server. Raspberry Pi has no open ports to the world but is accessible through Wireguard tunnel from the remote server.

WireGuard Site-to-Site.

Share 4G internet connection to wireless devices. Could use Raspberry Pi's internal wireless (hostapd) but external routers offer better range and dual bands (ESP8266 has no 5Ghz wlan).

Share existing wireless network to wired ethernet device e.g TV.

Add Raspberry Pi HQ Camera as a security camera with Motion Eye.

Scrape energy consumption data from Vattenfall Oma Energia daily.

Airplay server. Can use Raspberrys audio-out jack or USB dac.

Sketch files below are for Wemos D1 Mini ESP8266 device. They connect to Raspberry Pi network, read measurements once per minute and send them as a MQTT message.

Waveshare MG996R Servo linked to temperature knob of central heating unit. Two waterproof 1-Wire DS18B20 digital temperature sensors reading outbound and inbound temperatures.

BME280 sensor for indoor temperature and includes support for another 1-Wire DS18B20 sensor for outdoor reading.

The same as BME280 above but in addition has support for air quality sensor combo board (CCS811).

Tested on ESP32 devices only.

ESP32 device with connected E-paper display shows latest temperature measurements.
