Updated 2021-05-21 ! 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. Raspberry USB SSD boot made simple ? Check link  

Updated 2021-04-15 ! A cheap and simple way to measure temperature, and have it displayed in the Home app, is to connect one wire (1W)  DS18B20  (DS)temperature sensors direct to the Raspberry Pi(RPi) and install a DS plugin. This assumes that You have Homebridge up and running on a Raspberry Pi  Check this post !!    "ANY" temp source  can be HomeKit enabled.

Sometimes you have to handle things in Wordpress that you can't find any plugin for. In our case I had to visualize a list from a MySQL database and in another case I had to fetch data from another website. In both cases I solved it with inserted PHP code which is executing and getting the info.

Updated 2021-03-13 ! Here I'm trying to do the "ultimate" SignalK switch blog post including( no N2K) Shelly 1 as the hardware switch NodeRed as the function engine NodeRed dashboard as input/output interface WilhelmSK as input/output, check picture A http endpoint as state sensing The post is ment to be a template where you can pick the parts which are right for your setup.

I'm always a little confused that as soon as someone wants to get an analog measure to a Raspberry Pi(RPi) they are often taking a detour via an Arduino/ESP or some other microcontroller.  Why not just take an Arduino peripheral and use it together with a RPi ?  In my case I needed to measure the voltage across a fresh water tank level sensor in our boat, but i could be any DC voltage. Hints for sending the data to a   Signal K (SK) server is found below.  In this post I will use an ADS 1115 (AD), or ADS 1015, as AD converter.

In a former post I installed CUPS printer software for a Cannon printer. The scanning functionality is supported by the package SANE . But there is no nice GUI for the scanning function so I made one, with NodeRed(NR), which I really think is "wife" enabled.

Having Homebridge (HB) up and running it's simple to retrieve and visualize  status or measurements from accessories. 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.  To visualize the measured values over time I'm using NodeRed (NR) and a HomeBridge plugin

There are several mail merges applications where you can merge information from Google:s "Sheets"(GS), but not so may free ones that are good. The point using mail merge is that you can personalize your outgoing mails and you will fore sure get a better response rate.   There should also be said that if you are having a free Gmail account you are limited to 100 outgoing mails per 24 hours. The first application, free !, handles the merge via a GS with a built in JavaScript macro and in the second application, 25 free mails per 24 hours(limit in app), the merge is done via an installed GS add-on with many nice functions.

Do you know about the SignalK workspace at Slack ? It's a really nice space where you could meet the developers and also get support. If you don't are active there you can get an invite filling in your e-mail adress at http://slack-invite.signalk.org I'm following the dialog on Slack and for some weeks ago I stumbled over a post from @chris saying that you could get, with internet connection, the online charts from Eniro displayed in Freeboard. As you see in the picture it's just for the Nordic countries. Another post installing offline charts .
