Raspberry Pi Hardware project of Autumn 2023!

Idea

Be able to switch a 12V waterpump
Read voltage of the 12V battery the pump + rpi is connected to
Read if relay is on or not
Read air humidity + temp
Read soil moisture

Everything be remotly accessible

Docker

install docker:

https://docs.docker.com/engine/install/debian/

Todo

Phase 1

Update backend to return all sensor values
Update HTML to pull backend for values every second
Move to docker container
Create docker-compose with backend + nginx with basic auth & ssl
Add some nice CSS

Phase 2

Start testing 4G modem

~~- Setup so RPi connects to dyndns service on boot~~

Setup ssh tunnle on boot to sshserver

ssh-server:

install:
- nginx
- certbot
setup cert:

sudo certbot certonly --standalone -d example.com -d www.example.com

Stored here:
- /etc/letsencrypt/live//fullchain.pem
- /etc/letsencrypt/live//privkey.pem

Wiring

Can be found here

How should things be connected at the place?

The white connector has four inputs:

[White] [Black] [Black] [White]
    1      2       3       4

1 = Incoming 12V via fuse 2 = Ground 3 = Ground 4 = Incoming 12V via fuse

12 Battery:

- goes to inline fuse -> 4
- goes to linline fuse -> 1
- goes to 3

Water pump:

Pin 87 on relay (the pin not shoed) is 12V+
Connect pump negative to ground

Preview

Connect ssh

ssh into bastion host on @sshserver.local
From that, ssh via tunnel on @localhost -p

Home assistant setup

configuration.yaml needs this:

http:
  use_x_forwarded_for: true
  trusted_proxies:
    - 127.0.0.1
    - ::1

mqtt

Create password for user:

exec into mqtt container

run

mosquitto_passwd -c /mosquitto/config/password.txt sensors

Influx

bucket needs to be named "Home Assistant"
username and password is for connecting to UI
Home assistnat should connect using token
Token can be found in influxdb config file that is generated during boot

Config looks something like this:

[default]
  url = "http://localhost:8086"
  token = "<TOKEN>"
  org = "home_assistant"
  active = true
#
# [eu-central]
#   url = "https://eu-central-1-1.aws.cloud2.influxdata.com"
#   token = "XXX"
#   org = ""
#
# [us-central]
#   url = "https://us-central1-1.gcp.cloud2.influxdata.com"
#   token = "XXX"
#   org = ""
#
# [us-west]
#   url = "https://us-west-2-1.aws.cloud2.influxdata.com"
#   token = "XXX"
#   org = ""

skriv upp hur saker ska kopplas in
Mounta upp log-filerna från alla containerar så att de sparas på pien
