During summer 2018 Davis are updating WeatherLink to 2.0 (WL2). So if You have registered devices before 2017-11-28 You must migrate. This update is changing their website, as shown in picture, and API . Their API documentation is found here The following information is sent out in 2018-06 to users who still haven't upgraded to WL2

Updated 2018-06-07! The SignalK server(SK), the engine in OpenPlotter(OP) is coming with new releases pretty often and if You want to update, having used OpenPlotter RPI V 0.10.0 NOOBS , the following instructions will help You. I really recommend to start all over with a new fresh installation with the new OP V1.x.x.

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 .

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 .

Updated 2019-05-12 ! I have got some questions which version we are using for the moment at the site vader.domsten.nu   The version is from 2019-05-12 and You can get the whole site code from here . Please note that I have done some modifications so if You want the original code please rename  menu.php

ViewSonic SC-T25, VS,  handles certificates , cert, for different applications in  Base64-encoded DER format . If You open the certificate file, with a simple text editor, it shall begin with  "---- BEGIN CERTIFICATE ----" and end with  "---- END CERTIFICATE ----" if it is the right format. The most simple way to load the cert, is to use "Method 1" . Please note that You log in with the  CLIENT , PC/Mac, user/password. Another method is "Method 3" . In this example I will load Citrix Intermediate Certs to the  SC-T25 from a USB stick.

This cost effective Thin Client is based on Raspberry Pi 3 and together with Stratodesk OS it is very versatile If You bought, or got, the thin ViewSonic client, VT, produced before date 2017-07, You can upgrade to the better Stratodesk NoTouch OS with out any cost. This OS  is the "standard" OS for new devices.

We bought a nice LED lamp,  Nemo Ellisse Pendant Double ,  which was said to be dimmable, but when receiving it there was a big IF  !!!  The lamp was not "standard" dimmable, instead it was dimmable with 1-10 VDC or 100 Kohm potentiometer. The 1-10 VDC control is common in big installations, in public environment, since it can control a lot of lamps with one dimmer. Checking the lamp I found that the AC/DC LED driver was a Mean Well LPF-90D   and in t he drivers specification  the second IF was  found !! The lowest control level didn't switch of the lamp
