HomeKit bridge with Telldus Live

     Updated 2019-03-18 !


Do You have Telldus devices up and running and want them to be visible and used in Apples Home app ?

With some software and a Raspberry Pi(RPi) they will appear in the HomeKit environment.

Please note that as per 2017-10-22 the Telldus plugin is updated to V1.x and demands Node 8.3 or greater. Upgrade tips of Node from 6.x.x to 8.x.x is found hereThe new version can also locally "talk" direct to a TellStick ZNet Lite Vx.

RPi install Apache/PHP WEB-server


Updated 2019-02-18 !

As a part of one of my project, the ultimate Weather site ?? Weather34, I needed a WEB-host with PHP.

I started up with a fresh Raspbian Lite SD Card with Samba installed.

If using an old installation update the OS with 

sudo apt-get update
sudo apt-get upgrade
sudo apt-get clean

Log on, with ssh, to the RaspberryPi(RPi), with in this case hostname "pws01", and start to install the Apache server with

$ sudo apt-get install apache2

HomeKit, Trådfri and Gledopto RGB


I bought the Gledopto RGB+CCT LED controller(GO), so I could use RGB LED strips, not just the IKEA ones.


There were some IF:s, which will be scrutinized below, but it worked.

HomeKit bridge with IKEA Trådfri, Outlets



As said in this Bloggpost the Trådfri Gateway is supporting Apple HomeKit but for the moment it just handles the Lamps

With HomeBridge up and running You can use the homebridge-ikea-tradfri-gateway plugin to enable Lamps and outlets with the Apple Home app.

In this post will install the plugin.

AIS for Raspberry with Map, Dispatcher

This is a setup, on a Raspberry Pi(RPi), with a software package, rPiAIS, from http://www.aishub.net which includes
  • receiving and processing of all standard AIS messages
  • streaming raw AIS feeds to multiple destinations
  • advanced monitoring of device status, coverage and message statistics
  • embedded electronic map with all received vessels
On the same RPi I have installed a RTL-SDR dongle, approx 20 €, as the AIS receiver and then using the software aisdeco2, 2 channel support, interfacing the dongle and sending NMEA 0183(N1) data to rPiAIS.

Here is "stripped" version of an AIS receiver

RPi Raspbian install with Mac


Updated 2019-01-22 !

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 the ssh client from Your Mac

Connect the card reader, with the SD card inserted, to Your Mac and format the card with SD Formatter and use the "Owerwrite Formate" option. This will also check that the SD card is OK.

Here You find a post with headless WiFi install.

Raspberry headless install with WiFi

To make a headless, (without monitor, keyboard and mouse) install of Raspbian, Raspberry Pi:s Operating system, 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 the newer Raspberry Pi 3 Model A+ don't have any LAN cable port so the setup can be quite usable.

Homekit with broadband speed measure


If you think it's ok that the broadband speed appears as temperature in Home apps this plugin is very nice.

The plugin, used with Homebridge(HB), measures Your broadband speed at chosen intervals. If You use the free app "Eve for Homekit", besides that it shows the last measured broad band speed, it also shows the speed history in a nice graph.

Internet speed measure

New to Node-Red(NR) and maybe start with a simple application You even can benefit from ?

This application is measuring Your Internet connection at chosen intervals using Speedtest.net and showing the result in a graph. If the speed is under a set value it will send You an email.

Node-Red quick install



This post isn't made as a complete install guide, there are several, just some links to the best information I have found.

Node-Red(NR) is Flow-based programming for the Internet of Things.

The best thing is that even if You don't are a skilled programmer, but like logic flows, You can make really advanced things. It's pre-installed on some Raspberry Pi(RPi) distributions.

Speedtest vs ISP and home

Sometimes you are doubtful about the performance of your network, or ISP, and wonder, where is the bottleneck ?

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.

A speedtest, 
  • checking Your ISP, with just a bash script
  • for Your home network

HomeKit bridge with Z-Wave

Other HomeKit posts on this Blogg
Updated 2018-11-04 !

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.

Router as WiFi extender

Extending Your WiFi via cable have the advantage, compared to extending via WFi, that You keep the bandwidth at max. Extending Your WiFi with products that use the same frequencies, as Your WiFi, will just put through 50% of the data flow.

One way to extend the WiFi is with a cheap router, or maybe an old router You don't use any more.

IKEA Trådfri gateway install & HomeKit

Updated 2019-02-05 !

Using Homebridge for a while, getting nice hardware to emulate Apples HomeKit devices, I finally decided to test IKEA:s Trådfri concept.


The actual device that I was interested in is the new wireless control outlet. But they have bulbs and other stuff that is really nice priced.



This post will cover an installation of the Trådfri gateway and the outlet with a HomeKit approach.

NMEA WiFi gateway

The WilhelmSK app
           Updated 2018-10-15

I have searched for a solution transmitting the NMEA data, from the navigation network, via WiFi, to for example iSailor or other Tablet applications.

One way is OpenPlotter(OP) and another way could be SignalK(SK). Both applications use the Raspberry Pi(RPi).

Both OP and SK uses SK as the "engine", but using just SK will give You the stripped version without additional software.

WeatherLink weather template

If You are interested in building Your own weathersite with information from Davis Weatherlink(DWL), and don't are a skilled programmer I can really recommend Node-Red(NR). In this post I give an example how to start with the NR dashboard GUI.

If You want a more advanced weather site this is a very nice one coded in PHP.

Exhaust temperature measure, boat


In my post i blogged about a way to measure temperature with a Raspberry Pi(RPi) together with the marine applikation SignalK(SK). (Of course You can apply it to any solution running RPi). In this post I will follow up with a short brief about the practical solution, measuring exhaust temperature in a boat and sending an alarm if the temperature exceeds a set value .

In "wet exhaust" systems it is very important that the cooling water, injected in the exhaust system, always is present otherwise major damages can follow. The best way to monitor this is to insert a temperature probe into the exhaust pipe about 150 mm after the water injection point. Other methods will be too slow avoiding damage.
