Name: 	ThK1220RealGreenhouse
TOKEN: 	<api_token>
ChatID:	<chat_id>

Raspberry Pi OS image

Boot raspi and connect via ssh

Configure (static) IP

adapt /etc/dhcpcd.conf
sudo service dhcpcd status 
sudo service dhcpcd start // if not yet started 
sudo systemctl enable dhcpcd 
sudo nano /etc/dhcpcd.conf
sudo reboot

Retest and doublecheck network conection and settings before executing next steps!!!!!

Make updates and adapt main config

sudo apt-get update --yes && sudo apt-get upgrade --yes
sudo raspi-config
    Hostname:	greenhouse
    User:		pi
    Password:	******************
sudo rpi-update //update firmware
sudo reboot

Install and configure dyn dns client (ddclient)

ignore config let it empty e.g can be configured due next steps

sudo apt-get update
sudo apt-get install libio-socket-ssl-perl
sudo apt-get install ddclient

use e.g. FreeDNS and update ddclient.conf accordingly the dns provider


sudo nano /etc/ddclient.conf
other possible method could be e.g insert crontabs
0,5,10,15,20,25,30,35,40,45,50,55 * * * * sleep 31 ; wget -O - http://freedns.afraid.org/dynamic/update.php?******************************************** >> /tmp/freedns_greenhouse_my_to.log 2>&1 &
3,8,13,18,23,28,33,38,43,48,53,58 * * * * sleep 44 ; wget -O - http://freedns.afraid.org/dynamic/update.php?******************************************** >> /tmp/freedns_greenhouse_chickenkiller_com.log 2>&1 &

Install and configure remote ftp if required

sudo apt-get install pure-ftpd
sudo groupadd ftpgroup
sudo useradd ftpuser -g ftpgroup -s /sbin/nologin -d /dev/null
sudo mkdir /home/pi/FTP
sudo chown -R ftpuser:ftpgroup /home/pi/FTP
sudo pure-pw useradd upload -u ftpuser -g ftpgroup -d /home/pi/FTP -m
sudo pure-pw mkdb
sudo ln -s /etc/pure-ftpd/conf/PureDB /etc/pure-ftpd/auth/60puredb 
sudo service pure-ftpd restart

Configure the live stream

install motion and update /etc/motion/motion.conf
sudo apt-get install motion -y
sudo nano /etc/motion/motion.conf   //additional: output_pictures off
sudo nano /etc/default/motion
mkdir /home/pi/Monitor
sudo chgrp motion /home/pi/Monitor
chmod g+rwx /home/pi/Monitor
sudo service motion start

Configure port forwarding in router accordingly the dns and port settings

my live url

Install required packages (python, python-telegram-bot, python-pip, telepot and wiringpi)

sudo apt-get install build-essential python-dev python-pip python-smbus python-openssl git --yes //python
sudo pip install python-telegram-bot
sudo pip install telepot
First check that wiringPi is not already installed.
gpio -v
If you get something, then you have it already installed. The next step is to work out if it’s installed via a standard package or from source. If you installed it from source, then you know what you’re doing – carry on – but if it’s installed as a package, you will need to remove the package first. To do this:
sudo apt-get purge wiringpi
hash -r
WiringPi is maintained under GIT for ease of change tracking. If required to install do it like described as followed.
sudo apt-get install git-core
sudo apt-get update
sudo apt-get upgrade
cd git
git clone git://git.drogon.net/wiringPi
cd ~/wiringPi
git pull origin
cd ~/wiringPi
./build

Add scripts in pi user directory

e.g in this case in scripts/TelegramBot

Make them executable and chown root:root!

Enable autostart of the bot application

Add the program as service. To enable autostart add it to the init.d directory, insert telegrambot.sh in /etc/init.d as root and execute commands as followed.
sudo chmod +x telegrambot.sh
sudo update-rc.d telegrambot.sh defaults
sudo reboot

Additional functionality

Add as required or wished
Crontabs examples
# update check every 10 minutes
0,10,20,30,40,50 * * * * bash /home/pi/scripts/TelegramBot/update_bot.sh <access token repository> <chat id> <api token>
	
# update check every hour
0 * * * * bash /home/pi/scripts/TelegramBot/update_bot.sh <access token repository> <chat id> <api token>

# backup bot every day at 1:30AM
30 1 * * * tar -zcf /home/pi/backups/greenhouse.tgz --exclude='*.pyc' /home/pi/scripts/TelegramBot/

# also move log backups to backup folder
31 1 * * * mv -v /*.gz /home/pi/backups/
Logrotate to compress and clear log files
sudo nano /etc/logrotate.conf

/update_bot.log {
	missingok
	daily
	rotate 1
	compress
	dateext
	create 644 root root
