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

Updated 2021-12-14 A newer post in the same subject !! Sometimes You want to "take home" Your latest trip on sea and "replay" it or replay it doing some changes in the settings for the OpenPlotter or OpenCPN applikation and se the result direct. One way is to create log files with the the "raw" NMEA data and then use them at home with tips from this  post . Creating log files from NMEA 2000 bus , N2K, is the most straightforward.

Updated 2018-06-26! If You started with my quick instal guide You are a little familiar with OpenPlotter, (OP), basics and now we proceed with the sensors. Don't forget to delete the RMC sentence from the  "NMEA 0183 generator" which we used. Link to a stand alone AIS  receiver. Not valid for OP Beta V2 !!   Check here !

Updated 2021-02-23 ! A  newer post  in the same subject !! For Openplotter V2 check here To test Openplotter, (OP), together with OpenCPN,(OC), without connecting to the navigation network on board there are two features  Using the NMEA generators, found in the OP "Tools" menu  Use log files which are stored within the SignalK application.

Updated 2018-02-14 ! This backup method will make a copy/image of the whole card even if there is very little data on it. So if the card is 16Gb, the backup file also will be 16Gb. On the other hand You can ZIP the image file to save space. Another, maybe smarter ?,  backup method is described here .

Updated 2017-08-25 ! If You have a Private Weather Station(PWS) and would like to have a good view over the data and, as an add on, also forecasts from Weather Underground  (WU) this free software probably solves Your problem. Despite that the project is terminated the code is available and instructions is available at my other posts https://weather34.com/homeweatherstation/
