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
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
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 !

Victron monitoring solution, Venus, on Raspberry
Updated 2022-09-18 !
Victron have a state-of-the-art monitoring solution used by the GX products. It can monitor their other system components such as inverter/chargers, solar chargers, shunts, and batteries both local and remote all over the world.
If you have a smaller Victron solution it is nice to know that the same software, Venus OS(VOS), can run on a Raspberry Pi(RPi) instead of the more expensive and versatile GX products.

macOS Monterey on unsupported Mac
This is despite that max OS for the Mac is High Sierra. This is done, among other things, due to that the patcher handles Macs with graphic cards from 2008 - 2011 which Monterey doesn't do natively.
Since my former upgrade, to Big Sur, included a format of the SSD disk I here used the patcher to do an upgrade from Big Sur to Monterey.

SIGNL4, automated alerting with free mobile app
They have several ways to create an alert, can involve a team, have a nice app and is free, up to 5 users, if you use the "STARTER" option.
In this post, as an example, I will show how I detect if my AIS receiver/dispatcher stops receiving AIS targets, sent to Vesselfinder, and how an alert is forwarded to the SIGNL4 app.

HomeKit bridge with Z-Wave
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, acts as a messenger; the more devices you have, the more powerful and strong your network is.
