Domoticz

Hi, NashLena,

As I understand you want to install Domoticz on a Raspberry Pi and you successfully installed Raspberry Pi OS (formerly called Raspbian).
The IP address of your Raspberry Pi is issued by your router.

I would not do that and I recommend to assign a fixed IP address to your Raspberry PI.

You use Putty to connect with ssh to your Raspberry from Windows. Okay so far.
You indicated in your profile that your target OS is Windows. This is not the case, your target OS is Raspberry Pi.
Windows is just used as a tool.

You said:

Started Putty and in Session window, host name (IP address) used the PI ip address,

But did you enable the ssh server, while installing Raspberry Pi OS? This is important

That is correct and you should be connected to a terminal.
Default the user name is "pi" with the password "raspberry", without quotes. Change that for security reasons.

The Putty docs talked about linking to a server. My Pi is not a server correct?

Before you have installed a "server" and started the server it is not a server. But if you have enabled ssh and started the ssh server, then it is a server.

5. Copied domoticz_linux.... to a usb stick and saw the files from the stick. Tried to extract them and got lost over and over again.

No, follow this procedure

Step 1: Prepare your Raspberry Pi and install the OS: https://www.raspberrypi.org/software/

Step 2: Prepare your Raspberry Pi OS and enable ssh: https://www.domoticz.com/wiki/Initial_R ... y_Pi_Setup
You can setup a fixed IP address in this step.

Step 3: Install Domoticz: https://www.domoticz.com/wiki/Raspberry_Pi

if the pi is installed without keyboard, mouse and screen (headless) and neither ssh or vlc are enabled, do the following:

put the sd card in your win10 pc, and add a file ssh in the boot partition (the fat32 partition readable under windows)
ssh file in lower case, 0 bytes. (use notepad to create empty ssh.txt, and rename to ssh)

that will enable the ssh server at boot, and should enable you to use ssh to get to the pi

i mostly use vnc to get to the pi, much more convenient than ssh.
