  • Hmm. They’re dirt cheap so that is a pro. I don’t think they’re made to withstand mechanical load. So good for internal connections but less so if you’re moving around the wires constantly. There are beefier and more elaborate connectors available for that. But in my experience the JST connectors do their job well for normal electronics projects.

    One thing to consider is the current rating. A quick googling tells me a common JST connector is rated for 3 Amps. That’s not a lot. About 75 LEDs per connector to stay within the limit. (Given 5V WS2812 RGB at full brightness. Or ~220 if it’s 12 Volt strips) So if your led strips aren’t longer than that, I’d say you’re fine.

    But I’m not an expert on those things. I can’t tell you whether to choose the SM family or another one… But:

    The Wikipedia article says JST SM connectors are used in some LED strips…

    (So. I’d use them. But they’re not “the best solution”. They’re the minimum to do an alright job, make sure you can’t connect them backwards etc and apart from that, made to be as cheap as possible. The best would probably be some high quality german engineered products or sth like that (the country doesn’t really matter…))






  • No, I mean for the input sensing. To see if someone pushed the switch for the hood… The shelly 2.5 has 2 outputs and 2 additional inputs for switches. You cant’t control a third device. But you can measure if there’s mains voltage on 2 additional inputs. If wired correctly to the switch of the hood… You can detect if it’s on and control the 2 damper channels all with one shelly 2.5

    I think the 2 outputs are like controlling blinds. That’s a fairly common use-case for something like a shelly 2.5 and should work fine.


  • Your Shelly 2.5 also has 2 inputs: SW1 and SW2. You could also wire one of those in to the hood so it can directly detect if it’s powered. If that’s possible… Idk, it needs to be after its switch. likely the hood isn’t made for this and you’d need to mess with the internal wiring. Your setup is a bit easier.

    I’m not sure what happens if both channels are active simultaneously… Some devices handle this and prefer one direction, but not all of them. I can’t tell from the eBay page.









  • Idk. That ‘study’/article fails to recognize the consequences and ethics of the legal situation in Japan for example. And I think everything is a bit too vague to really claim to be scientific.

    This topic sometimes makes me a bit angry/disappointed. On the one hand I perfer my favorite places on the internet (eg the fediverse)/not to be used for disgusting stuff and crime. On the other hand politicians like Ursula von der Leyen, who is now head of the EU parliament, have been using exactly this subject for years (and in my eyes thus abusing the stories of the victims yet again) to advertise for 100% online-surveillance, getting rid of end to end encryption and storing massive amounts of data about everyone, just in case…

    “Just think about the children…”

    And this is just not the way to solve that issue. I don’t want to live in their 1984-society fantasies and there are better solutions around.

    A second thing I find kind of alarming. The article mentiones those automatic content detection tools by Google and Microsoft. They are NOT available for the free world. I think if legislature really forces us to filter on upload… And it’s only big corporations that own the databases of CSAM… This is their way to easily get rid of the fediverse. And every platform build by and for the people.

    I’m a bit disgusted. But this is why i’m interested in the subject.




  • Me neither. Sorry. I just heard in the podcast that scripts now can return values. And we can always store state inside of some input helpers. But if you don’t find a solution or an idea of how to do it in the forum, it’s maybe not (yet) possible this way. Or too complicated.

    I have a few other things to do before i can start fiddling around with Assist and soldering some voice assistant for the kitchen.
