I stumbled upon NodeRed when I searched for an alternative to openHAB to control my 433MHz switches. openHAB ist too heavyweight for my use case. I detected NodeRed and created a NodeRed Flow with a dashboard in a couple of days and I like NodeRed now. I used the HTTP-Request node in order to contr…

Have you tried this? [image] cinhcet: you said you get this list from some server, right? I guess as a json file? Then find out how to use jquery to get a json file into the editor of your node, something like $.getJSON('http://YOURSERVER', function(data) { blablabla }) The link I posted sho…

Sorry for the confusion. I thought I make it easier for you. In order to achieve that, l…

[image] cinhcet: ... but posting complete finished solutions will not help you the next time. Therefore, it is always better to try and report on problems you encountered. Not sure I get your point. I consider my code as not final given I'm new to JS - and thus I'm open for comments. But as l…

I meant that it is not helpful if others give you the complete solution

[image] cinhcet: for more details, look at JGKKs links Will do :slightly_smiling_face:

[image] cinhcet: I meant that it is not helpful if others give you the complete solution Hm ... there is some misunderstanding ... I don't want to get complete solutions. That way I don't learn any new stuff ... Why do you think I look for a complete solution? I just ask for some hints and li…
