      First batch of devices arrived. Looks fine. I hope I will manage to install it in garden to the end of the week.

      Nca78

      @Jonathan-Roberts said in Simple AC/DC Switch WeMos: @nca78 bummer. So I think 2 options... What if the Wemos is raised off the PCB. That would be almost 5/8". In your experience would that help? And maybe the best option, slide the antenna module straight down,. move the relay up and spin it around so the connections are on the outside edge. I'm trying to make this multi-purpose and allowing both headers to be fully functional to other projects. thx for the advise. 1 would help but not that much. It's already not a good thing to have the transformer just next to it on the side, so you should avoid blocking one more direction with tracks. I don't understand your necessity to have connectors available for something else on the relay that is too high to put anything on top ? 2 sounds like a much better option, make sure you have nothing right and left of the antenna when you move things around. The problem you will have with this layout is the USB in that situation... It doesn't sound like a great idea to me to use Wemos on this board especially for the relay part, it's just a cheap chinese relay with 3/4 components so why not just put them directly on you board to make the layout so much easier ? I have the feeling that you're trying to make things "easier" by using Wemos and its shields, but in the end you seem to lose more than you gain. And neither does it seem "safer" to use their relay shield as it forces you to have extra wires between main of the HLK and relay shield connector.

      Hi @blackchart, Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).

      Hi @koresh - I had a little accident on the AC side :-). I was wondering what values the 2 resistors (TH and SMD) and diode are ? Thanks!

      Hi @aramko-aramko. Unfortunately, this model is already sold. You can look at the upgraded version of this device - MDMSNode "Lighting" Rev 1.1.

      Do you really need a compact device?

      That is what I do, I create a rule to pads with creepage and rely on my calculations. I'm rebuilding my current switch board to make it safer to use in more polluted environment, I need to use one outside (in a box, but better safe than sorry), and in a bathroom. I think that the main problem with the pads and traces spacing is the design constrains. I need to keep it in a 5x5 cm board and that is not easy, especially when you have a AC and DC circuit! I never considered the distance between AC and DC, and that is the main reason for me to rebuild my boards. After reading your post I made some researches, and I found that I had a design problem. Like you stated, I'm not a electrical engineer, and we are always learning

      What varistor should I use for 240VAC in Australia? The linked AliExpress item is no longer available.

      @sundberg84 I was able to do a photo, so the dallas temp, and le33 "mask" is on the opposite side, I think this is the problem. (in your example pictures they are on the good side) No worries, I use currently the newbie pcbs for light switching,
