- NodeRed as the function engine
- NodeRed dashboard as input/output interface
- WilhelmSK as input/output, check picture

For example I'm using the Aeotec MultiSensor 6,(AM6), via the z-way plugin, where I'm sensing the light level. Since Im living in northern Europe it's not very accurate to switch the indoor lightning by sun-rise/set. So instead I'm using the AM6 together with the EVE app to switch the lightning.

S1 is a WiFi switch, 16 Amps, but also a hub for temperature sensors.
With a great software package pre installed You probably don't need anything more, but since it is an ESP8266 You can also flash it with Your own/other software.
The function "without Internet" + that the S1 can use a 12V DC source makes it perfect for an "use case" in a boat/mobile home.
It's compatible with Alexa, Google or HomeKit using HomeBridge or Mongoose firmware

A very nice way to fix a backup is to make a copy, bootable, of the actual SD card You are using on the RPi. This will be done when the RPi is up and running !
This application can also be used to make a bootable SSD or USB drive !!
You clone from the command line so You don't need the standard GUI, Pixel, and the SD card copy function.
It is also possible to set up a cronjob, explained later, which for example makes a clone every night at 1 o'clock.

I like the Raspberry Pi(RPi), with Raspberry Pi OS Lite (no Desktop is included), headless operation, and then adding the software You need. Until now I haven't had a use case where I needed a Desktop but now was time.

When starting up a new project with Raspberry Pi I like to start up fresh and with a minimal OS. Therefore i always use Raspbian Lite. Doing it right You don't have to use an external display, keybord and mouse, just a ssh client.
Here You find a post with headless WiFi install.

If You want that the Raspberry Pi, RPi, shall appear in MS Explorer or Mac Finder, as a File server, the easiest way is to install Samba.
This also makes it much easier if You want to edit files on the RPi with editors from Your MS/Apple device. Or maybe moving files from/to the RPi.

These devices are available for Apples HomeKit. The devices are Bluetooth, BLE, or WiFi connected so it could be a limited range in Your house.
The Z-Wave solution have a smarter setup running on a type of network called a "mesh network". One Z-Wave product will pass the signal along to another (“hop”) until the final destination is reached. Every device, not battery charged, in your home acts as a messenger; the more devices you have, the more powerful and strong your network is.

Having used Node-Red on Raspberry Pi before, the first application was this dashboard.

- Create the setup you want on a ordinary SD card
- Make a bootable backup/clone of the SD card saving it to the USB SSD
- Remove the SD card and boot from the USB SSD

There is a post, link will follow below, from the Raspberry Org site which is very informativ and handles how to connect your external hard disk, SSD, or USB stick to any of the USB ports on the Raspberry Pi(RPi), and "mount" the file system to access the data stored on it.
So there is no need for a rewrite and this post will therefore continue with how to connect to a Windows server, (Other SMB or Samba servers will also work), both temporary and automagically at boot.
Check this post RPi booting from an USB drive !

The calibration could be done against standard GSM transmitters which are providing a stable reference frequency.

This post covers the setup for a AIS, dual channel, receiver for Raspberry Pi(RPi) with systemd autostart.
I'm using the RTL-SDR dongle V3 with almost zero temperature drift or the even better NooElec NESDR Nano 3

The gasket on our Kamado Joe was falling off after a very hot pizza cooking project. After some Googling, search link here, I found several post where people, to my surprise, used 3M™ Super 77™ Multipurpose Spray Adhesive.
I'm surprised due to it's just specified to handle up to 65 °C, 150 °Fahrenheit.
It was also not available in the nearest shops so searching a bit further I found ...

After some Googling I found some favorite applications, implemented on a cable connected Raspberry PI(RPi), which do the job so You can start measure and stop guessing.
