Weather34 & WeatherLink w/o cronjob

Running Weather 34, W34, using my setup, the program "cumulusdata.php" is fetching data from Davis Weatherlink(WL), and are writing the data to a file, type Cumulus. The old way was to fetch the data via a scheduled cronjob. 

Doing a small change to "windspeeddirection.php", "updater.php" , and using the latest version of "cumulusdata.php", will do the update with the built in W34 refresh routine instead of cron job.

Thanks to Ken who gave me the hint.

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 with broadband speed measure

Updated 2019-09-02 !

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.

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 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 with a HomeKit approach.

Raspbian Jessie to Stretch upgrade

Upgrading from Jessie to Stretch can break the entire system so ALLWAYS do a backup.

There are several sites/posts with "how to" information but the Raspberry site, the Linuxconfig site and the Superuser site, (where You can find more details about the upgrade), made the base for this post. 

Davis WeatherLink upgrade to 2.0

During summer 2018 Davis are updating WeatherLink to 2.0 (WL2). So if You have registered devices before 2017-11-28 You must migrate.

TP-Link Deco install with ethernet

TP-Link Deco is a smart Mesh system that extends Your WiFi.

It is pretty easy to install but there is no direct information in the install app, Apple or Android, about how to interconnect the Decos with ethernet. 

Especially if You must keep the old Router.

Connecting via ethernet is faster and more stable and also necessary if the Decos WiFi can't reach each other.

Another post with DECO:s in router mode.

Boat navigation network

In a former post a I presented our approach to mix a modern NMEA 2000(N2) network with the older Raymarine ST 1 network, installed 2006.

During the Years it has grown and been added with new functions. The pictures to the right is the actual layout.

The first add on was a N2 GPS described here.
