Letsencrypt with Zonomi

Setup acme.sh

• git clone https://github.com/Neilpang/acme.sh.git
• cd ./acme.sh/
• ./acme.sh --install
• export ZM_Key="zonomi API Key"
• acme.sh --issue -d wjw.nz -d *.wjw.nz -d wjw.co.nz -d *.wjw.co.nz -d wjw.co.uk -d *.wjw.co.uk -d wjw.uk -d *.wjw.uk -d walkerfamily.kiwi -d *.walkerfamily.kiwi -d *.nzags.com --dns dns_zonomi 

for mailinabox add "--config-home /home/user-data/ssl" to acme command line and run the following:

    cd /home/user-data/ssl

        rm ssl_certificate.pem 

        ln -s wjw.nz/wjw.nz.cer ssl_certificate.pem

        rm ssl_private_key.pem 

        ln -s wjw.nz/wjw.nz.key ssl_private_key.pem

To fix cert error with curl:

• wget http://curl.haxx.se/ca/cacert.pem
• mv cacert.pem /etc/ssl/certs/
• nano /etc/php/7.0/cli/php.ini 
• add "curl.cainfo ="/etc/ssl/certs/cacert.pem" under "[curl]"

For mixed DNS hosting

acme.sh --issue --force -d walkerfamily.kiwi --dns dns_gd -d *.walkerfamily.kiwi --dns dns_gd -d wjw.nz -d *.wjw.nz -d wjw.co.nz -d *.wjw.co.nz -d wjw.co.uk -d *.wjw.co.uk -d wjw.uk -d *.wjw.uk -d *.nzags.com --dns dns_zonomi

Creating ASA Cert Package from LetsEncrypt certs on Linux

openssl pkey -des -in /etc/letsencrypt/live/asa.wjw.nz/privkey.pem -pubout /etc/letsencrypt/live/asa.wjw.nz/pubkey.pem

openssl base64 -in /etc/letsencrypt/live/asa.wjw.nz/cert.pem > cert.base64
openssl base64 -in /etc/letsencrypt/live/asa.wjw.nz/privkey-enc.pem > cert.base64

openssl pkcs12 -export -out /etc/letsencrypt/live/asa.wjw.nz/certificate.pfx -inkey /etc/letsencrypt/live/asa.wjw.nz/privkey.pem -in /etc/letsencrypt/live/asa.wjw.nz/cert.pem -certfile /etc/letsencrypt/live/asa.wjw.nz/fullchain.pem

cp /etc/letsencrypt/live/asa.wjw.nz/certificate.pfx /media/nas-backup

One-Wire Temperature collection, publishing to EmonCMS using OmegaOnion

I needed a quick solution to log the temperature of my hot water cylinder at home, had an Omega Onion lying about so used that.

OmegaOnion
OmegaOnion EXP Dock
2 x DS18B20 Sensors, wired together with a 5K7 pull-up resistor

From a factory reset:

• echo "w1-gpio-custom bus0=0,19,0" > /etc/modules.d/55-w1-gpio-custom
• reboot
• Find the names of the sensors, "ls /sys/devices/w1_bus_master1/
• opkg install curl
• opkg install nano
• nano temp.sh

#!/bin/ash

temp1=$(awk -F= '/t=/ {printf "%.03f\n", $2/1000}' /sys/devices/w1_bus_master1/28-000006560975/w1_slave)

temp2=$(awk -F= '/t=/ {printf "%.03f\n", $2/1000}' /sys/devices/w1_bus_master1/28-0000065711e6/w1_slave)

curl --data "data={temp1:$temp1,temp2:$temp2}" "http://192.168.1.129/emoncms/input/post.json?node=55&apikey=xxxxxxxxxxxx"

printf "\n"$temp1"\t"$temp2

• Then all you need is to create a cron job, crontab -e

*/5 * * * * /root/temp.sh >/dev/null
