Homebridge made simple, Homebridge

Updated 2023-10-26 !

HomeBridge(HB) is the software where You make Your home automation devices appear in the Apple Home App as native products. In this post a Raspberry Pi is used as the HB server.

There has really been big improvements in the installation process and I think the HB version is better/easier than HOOBS.

Raspberry headless install with WiFi

Updated 2023-10-17 !

To make a headless, without monitor, keyboard and mouse, install of Raspberry Pi OS on a Raspberry Pi(RPi) with built in WiFi and no LAN cable connection, please follow the instructions below.

For example the RPi Zero and Raspberry Pi 3 Model A+ don't have any LAN cable port so the setup is quite usable.

To make an active WiFi connection at first boot You have to use the "Advanced options" in Raspberry Pi Imager or create, old way, a configuration file called "wpa_supplicant.conf".

Understand/Install Openplotter/OpenCPN/SignalK, I

Updated 2023-10-15 !

This post, additional posts will follow, will explain the purpose with, and quick/simple install instructions for, OpenPlotter(OP) and some other applications that can be installed with OP. 

• OpenCPN(OC), is the plotter software where You navigate and handle charts 
• SignalK(SK), is the software where all the sensor inputs are handled. Could be NMEA data or SK formated inputs
• OpenPlotter(OP), is the administration shell where all is administrated

As You investigate the different software packages You will see that there are some overlap in the functions.

With OC 5.2 + there was several updates....

NetworkManager on Raspberry, easy start

Updated 2023-10-13 !

There is a "new kid in the block" called NetworkManager(NM), configuration of network interfaces, which in OS "Bookworm", Debian 12, is replacing the former used dhcpcd.

NM isn't really new since the first public release was made 2004.

In this post I will write down some NM hints for an easy start since I didn't find any myself.

NetworkManager UI and access point, hotspot

Updated 2023-10-12 !

In a former post I shared some thoughts about how to start using NetworkManager (NM), on a Raspberry, and here I will continue with additional examples that can help with network setup.

• NMTUI is NetworkManager text UI which can handle the most common tasks in a easy way.
• An access point or hotspot will be configured.
• "sudo nmcli connection edit xxxx" is a command that guides you throw a change of parameters.

TP-Link Deco M9 V2 Plus software update

Updated 2023-10-04 !

TP-link Deco M9(M9) is a nice Mesh solution but it could be that the software/firmware is dated 2019. This is an old one and you really shall update ! Probably you can't update via the TP-link Deco app and therefore you have to make some extra measures updating via a Mac/Windows program.

In a former post I gave some hints and links if you are using an ethernet backhaul, using access point mode, and please check below how to set up without a router and manage more than one network.

Post with Teltonika 4G router as receiver / bridge for the mesh network.

Bluetooth Beacon and Raspberry

Updated 2023-10-02 !

The latest models of Rasberry Pi, (RPi), comes with built in Bluetooth, (BT), so how to receive data from Your Bluetooth devices ?

A Bluetooth Beacon, could be a RuuvuTag, is a device that You don't have to pair with, You just scan and receive the data that they are transmitting.

Start with checking that Your BT interface is working, in a terminal window, typing

Volvo C70, Mk1, convertible tips and trix

I own a 2003 C70 Volvo softtop convertible but at the age of 20 she got some problems with the softtop/cab. 

So this post will be some problem solving and links to information which could be handy. 

There is a private Facebook group which is active and helpful.

Remote access, remote.it, made simple

Sometimes it's really nice to reach your applications at home when you are somewhere else. 

There are several applications but this post will be describe a really quick setup with remote.it on a Raspberry Pi(RPi) or another Linux platform. Of course there also is a Windows version.

For non-commercial use, with up to 5 devices, it's free !

The most used services are; http, ssh, vnc, rdp, SAMBA(smb/cifs) .....

I'm using it to display NodeRed dashboard, access servers with "ssh" and file sharing with SAMBA there all applications are running on RPi:s at home.

Apple HomeKit doing Matter upgrade with Hombridge

Matter is the the new standard making your smart home devices talking to each other and some Apple Home hubs can be updated.

There is a nice article from "The Verge" which explains it all.

Using Homebridge(HB) it could be nice to know what happens when you upgrade your HomeKit hub to the new standard so his post will just give some quick tips

Here is a support article from Apple and please note that if you upgrade you will not be able to use an iPad as a Home hub anymore.

Optimizing your energy, electricity, bill. NodeRed !

In this post I will give some thoughts, high level, and methods for matching the hourly prices from your energy supplier.

I will also list some gadgets and by using NodeRed, get the data, visualize it and control the consumption.

So in that perspective there are some needed prerequisites.....

Bluetooth and Node-Red

Updated 2023-07-12 !

There are some Node-Red nodes, (NRN), that are dependent on the old Noble package which don't work on Node > v8. 

One nice and simple NRN is the node-red-contrib-noble which have the same problem. I picked up the freshest source, dependent on @abandonware/noble, forked it and added install instructions. It works with Node <= v18. 

Teltonika router as security, burglar, alarm !

The use case was that we on our yacht have a security alarm which is using 2 G, service terminating during 2024 ?, so it was time to check for some other solution. 

Since several years we have used the very nice Teltonika RUT 240(TR) onboard which have served us very well. Knowing that this device have both a digital in and out I started to check if it could do the job ?? 

Googling didn't give any direct clues but the "Input/Output" handling together with "Profiles" changed with a SMS, "Mobile Utilities", is doing the job.

Please note that this setup could be done with any of the routers from Teltonika with I/O !!

Bootable installer for "any" MAC OS, II

In a former post I used a nice Python program to get the installers but as you know there are no Python installed in later Mac OS.

The program used in this post is the fantastic Open Core Legacy Patcher. (No Python dependencies.) This patcher is made for supporting old Mac:s with new OS:s, which is not officially supported, but here we just use it for getting the USB installer.

Teltonika router RUT 240 quick setup

Updated 2023-06-01 !

My old boat/travel WiFi router didn't behave so I was forced to look for a new one with these must functions;

    Built in SIM 4G/LTE capabilities

    WAN failover

    Powered with 12V DC

    Bridge public WiFi:s, or my phone, to LAN

I did a lot of Googling and ended up with Teletonika RUT 240(TR).....

This post will cover a setup summary for the RUT 240 model, but it's useable for other Teltonika models too since they have a common firmware.

Check these posts ! Teltonika router as security, burglar, alarm !

Shelly 1 quick install

Updated 2023-05-04 !

This post focus on Shelly 1(S1), a really a nice automation device with great versatility, but much of the content is also valid for some of Shellys other devices using the gen1 API.

Setup for the later version, Shelly Plus 1, is found here !!

S1 is a WiFi switch, 16 Amps, with dry contacts and 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 as a "native" HomeKit device using Mongoose firmware(Flashed via a standard WEB browser !)

Shelly PLUS 1 quick install

Updated 2023-05-03 !

In a former post I made a writing about Shelly 1(S1) and this post will handle about the successor Shelly PLUS 1(SP1) but much of the content is also valid for some of Shellys other devices which uses the same software/API.

To keep it simple, SP1 is a WiFi switch, 16 Amps, with dry contacts but compared to the S1 the hardware and the software is updated. 

The function "without Internet" + that the SP1 can use a 12V DC source makes it perfect for an "use case" in a boat/mobile home.

HomeKit bridge with Shelly/Shelly 1

Updated 2023-05-01 !

I really recommend flashing, via WEB-browser, the device with Mongoose software to avoid Homebridge.

 
HomeBridge is used for this setup and to make it appear in the Apple Home app.

The main advantage with the Shelly devices are that they are WiFi enabled and therefore You don't have to use a hub, this compared to z-way/zigbee and some other solutions. 

First install Shelly1(S1).

Bootable installer for "any" MAC OS

Updated 2023-06-11 !

The use case is that I had an old iMac, max OS is High Sierra, that crashed and it didn't work with an Internet or Time Machine restore.

The other MAC:s I have are running Catalina or Big Sur and if you try to download and older OS, via app-store, you just get an error saying that the running OS don't accept the download of an old OS.

The universal way to create an USB installer seems to be using the command "createinstallmedia", requires OS X 10.7 Lion or later, but you need the respective OS install app !

A new, better ??, without Python dependences is found here.

macOS Ventura on unsupported Mac

In former posts, Big Sur(11.7) and Monterey(12.7), I went through how to update an old MacBook Air 4.2, (mid 2011, SSD, 4 Gb memory) which has a Non-Metal GPU.

In this post I will update a MacBook Air 6.2 with SSD, Mid 2013, to Ventura(13.5) with the same patcher but the latest version 6.2 !! 

This is despite that max OS for this Mac is Big Sur

Awesome !!!

Supported models are found here.

Node-Red on MCU:s, Raspberry Pi Pico W

Since I'm not a programmer, and probably never will be 😉, I really like Node-Red(NR). NR is also a nice way trying to learn some JavaScript via the function nodes.

I also appreciate hardware, MCUs, like ESP32 and Raspberry Pi Pico but find it a little hard to code in MicroPython or C++.

Somewhere ?? on the WEB i found some applications that can export NR json code to C++ and run it on several MCUs.

As you understand I had to check it out... 

Upgrade from Buster to Bullseye, Raspberry

Uppdated 2023-10-28 !

I have been running a Raspberry Pi 2(RPi) for several years with Buster and the applications;

• Homebridge(HB)
• Razberry, Z-way interface
• CUPS, printer software
• Node-RED(NR)

When I started with the RPi it was Jessie, then Stretch and Buster. Every time I upgraded the SD card to the latest OS and it just worked. It should been said that I always waited a year or so and I'm using the RPi headless without any GUI.

Now it was time to go from Buster to Bullseye !
