    You wanted small device that is also certified and the smallest solution I know are Zwave devices. I don't think you can find a certified product running on atmega controller with mysensors and be also certified

    @gohan I know the requirements are very specific and hard to find. I am just searching for ideas.

      It is just a matter of choosing commercial or DIY, that means certified or not certified :)

        oh, You are talking about this ?

        if so then yes this is exactly what I mean and actualy this item looks very good :) about the price I believe that maybe you could find something half the price but not less ...

        Yes, that is what I was talking about. Half the price sounds good.
        But to be honest, I think the one you posted suits it better. The Recom power supply's use cases seem to be the same as the HLK module.

          @exilit the one i posted is much bigger and 12v, so You need buck converter. This makes it harder to fit atmega board, but maybe You will :). for sure there is more 12v flush mounted power supplies and they are cheaper because they are used for led lighting. The cheaper ones will propably draw more power, they will be powered 24/7 so it is important that they draw at lest less than 0.5W.

            @gohan There is no problem. I like the devices very much, but I'd like to have something not WiFi based for that purpose.

            Why Z-Wave? Do you know a Z-Wave device, that serves low voltage output and is externally controllable?

              @Black-Cat Ideally 5V or 3.3V. But in the end it doesn't matter too much, as converting it down wouldn't be too difficult. Do you know something?

                @exilit For Z-Wave control the only device I am aware of that uses those voltages is a Z-UNO. You would need to build your own controller but it's not difficult.

                      @gohan the smallest PS that I know of that is enclosed is 62.55128mm (LWH)
                      available in 3.3v, 5v DC
                      https://www.meanwellaustralia.com.au/products/rs-15
                      There should be local distributors in the required region.
                      If the OP can do without an enclosed PS then there are smaller such as
                      this step down shield.
                      https://www.blackcatcontrolsystems.com.au/Chargers-Power Supplies-Connectors/Transformers/AC-DC Supply-240vAC-5VDC

                      There are many different relay's on the market, googling will turn up something that fits the requirement.

                      Sorry about the Z-Wave confusion.

                          I can do, but I am specifically looking for something that simplifies (in a sense of "assurance-safety") the whole High Voltage side. The products posted by you are really nice, but unfortunately do not address my request. :-)

                          Like I said before, I am aware, that the product I am searching for might not yet exist. (wondering why :confused: ) But maybe somebody has seen something like that.

                            I'd say because they don't want people mess with the product so they usually sell product with their own SW solution. It is like rooting a mobile phone, in case of problems you are out of warranty and in case something happens they are out of liability

                              @gohan Well, for most companies you are probably right. But have a look at ITEAD with their Sonoff products... They are already quite open and also seem not to do a lot against people tinkering with it. They sell good products which are adoptable if needed/wanted. And people obviously like it and large communities originate from that which create even better products.
                              So I think there is a market for those products.

                              That's what I mean, I'd like to see products where I don't have to void the warranty because I don't need to open it.

                              I imagine something like the following:
                              0_1503486411101_Device.png

                              I think that would be awesome.

                                For good AC-DC solution look at MeanWell and their IRM range, For example, IRM-05-5

                                  @exilit also ITEAD has a warranty sticker that you need to break if you want to reflash the relay. Could be a good idea what you proposed, maybe you can start a kickstarter campaign :D

                                    3D Printed Switch and Rear Box

                                    I created a switch and the box that goes in the wall in TinkerCAD. On the switch side, there is a little WS2812B led which i use to show states, and a little startup sequence to know its up and connected to the MySensors gateway. There are two buttons both behind the switch, one is pressed by the switch itself, the other is a reset switch which connects ground to the reset pin. This is in case it needs to be reset or something. I did this 2 piece approach for being able to take off the wallplate, pull out the switch, connect up the FTDI adapter and upload new code in the case of the MySensors nodes. For the ESP8266, those are OTA.

                                    I am printing the latest version of the box and switch now, I will upload pics when they are done.

                                    Here is the one in my garage, white means light is off (so you can find it in the dark), green is on. There is a red light coming from behind the switch which is the relay light, I dont care much in the garage so you can see it. On the inside ones, I used a small piece of heat shrink to cover it. Also, the pictures just do not do it justice at all, the light blurs out the camera and you cannot see the switch very well nor the power icon behind the LED.

                                    off
                                    on

                                      @exilit also ITEAD has a warranty sticker that you need to break if you want to reflash the relay. Could be a good idea what you proposed, maybe you can start a kickstarter campaign :D

                                      @gohan said in AC Power and/or Relay interface:

                                      I did not thought about that, but that sounds like a good idea :simple_smile:. Maybe it's worth thinking about it.

                                        So I did this recently, I have two ESP8266 Wemos based switches and 2 MySensors based in production right now with more MySensors on the way. They encompass the following from AliExpress:

                                        @Brian-Morris Great project, looks good. But I think also not what I am looking for.

                                          Np. I saw the "I am looking for a way to put an MySensors Relay actuator behind a wall switch." description. My project is a switch and relay in 1. Are you talking about just putting a MySensors node with a relay behind a working normal light switch?
