I replicated your set up, well except maybe the chair.
Quick check list here:
Raspberry Pi B 3?
Raspberry Pi powered with 2amp or greater supply?
Screen - HDMI?
Keyboard and mouse - USB? Wireless? (wired would also be fine, Not sure about Bluetooth.)
This makes your system console. All set up will be done from here.
Connected via network cable to eth0 on Raspberry Pi?
Installed NOOBS Raspbian Stretch (first option)?
Reboot?
See Raspbian Stretch PIXEL screen?
Main menu <Prefreneces><Raspbery Pi Configuration>Tab<Localization>
Changed localiztion settings (all to your local)?
Reboot yes/no YES?
See Raspbian Stretch PIXEL screen?
Start Chromium browser. OK?
http://forums.x10.com/index.php?topic=30205.msg172529#msg172529Go to X10 Forum OK?
PRE DOMOTICZ INSTALL ( you can copy and paste these commands from here to the terminal session.
In a terminal session
sudo apt-get update.
No errors? OK?
sudo apt-get upgrade.
No errors? OK?
Install missing library libssl-dev. Current version does not work. So, need to pull previous version.
wget
http://ftp.nl.debian.org/debian/pool/main/o/openssl/libssl1.0.0_1.0.2l-1~bpo8+1_armhf.debsudo dpkg -i libssl1.0.0_1.0.2l-1~bpo8+1_armhf.deb
No errors? OK?
DOMOTICZ INSTALL
In a terminal session
curl -L install.domoticz.com | sudo bash
No errors? OK?
sudo reboot now
CONFIRMATION
domoticz will show up in top. To confirm the daemon is running:
In a terminal session
top
See domonticz running?
Now, start Chromium
http://127.0.0.1:8080What do you see?
These are the steps I followed to get Domoticz running. Normally I do not use NOOBS. However, wanted to double check that did not have a effect. In this set up I eliminated any extra steps. Like network. You can make changes if you got this far. On the network set up I disable ivp6, even if eth0 or wlan0 are set to auto detect (DHCP). Also, on Chromium, there is an addin called blocked. It has a little red shield, upper right corner. You can tuern this off on a site ny site basis. Have not seen a problem with the sires above X10 or domoticz tho.
