💬 AC-DC double solid state relay module

@tonnerre33, je suis également en France et je n'ai pas de neutre dans mes interrupteurs. Peux tu me dire comment tu as pu tester le pcb stp. Mon anglais est loin d être top desolé !!
@laster13 hi, i have tried this pcb with my bedroom lamp. Indeed, these lamps are powered by electrical socket which include neutral wire.
For the others lamps, i need to find how to command them without neutral wire ;)
I am looking at this project but this is an smd project :https://www.openhardware.io/view/249/MDMSNode-Lighting
@laster13 salut, en fait mes lampes de chambres sont sur prises commandées (donc accès au neutre), du coup j'utilise ce module pour ces lampes mais pour les autres bin il va falloir que je trouve autre chose ;)
Je regarde un peu du coté de ce projet mais c'est du cms : voir le lien au dessus -
I Will tried to speak english 😗.
Thanks tonnerre33 for your help. Could you give me à shema of your installation in the bedroom ?Here is a schema of my installation without the node :

Sure you can use an electrical socket without switch control.
But caution, max current is 2A ! It is ok for lamps but you can't supply a receiver which consumes more than 460VA per relay ( = 460W for resistive receiver).
I didn't see protection for relays, be careful ;) -
I am trying to test a montage which I am not sure about and besides when I plug the pcb on the socket the lamp remains on. I invite you to read my post on the Domoticz forum.

Hi All,
This is my first post on this site!!
Yes this is a really good project but for the UK controlling a light inside of a wall switch you would need to do the following.
Re-wire the ceiling rose as in the UK there is a live feed from the rose that is switched by the switch and then returns to the rose to the "switched live" See http://www.diydoctor.org.uk/project_images/lights_and_switches/ceilingroseb2.jpg
Put an extra cable up to the ceiling rose with the return cable from the board that goes to the switched live and add an extra terminal in the ceiling rose to link the neutral to the other side of the lamp fitting.
If the back box is metal, it would need to be changed to a plastic box , I wouldn't myself want to mount the board in an earthed metal box!!
As other contributors have noted there isn't any fusing on the live and neutral feeds if the SSR were to fail short because of a short circuit in the lamp or ceiling rose then there could be a large current going through board that could potentially cause a fire, safety is always the first thought with any mains electrical circuit.
I could see this board being used in a plastic box inline to a table lamp etc. but it would need a lot of work to re-wire your house if you intended to use it behind a wall switch.

@laster13 Yes your schema is correct.
The sketch has been modified by Nca78, you can try it first.
The problem does not come from the unused switch, because i use this node without switch. -
@Hilltan Hello, i think this link will be ok : http://dirtypcbs.com/store/details/885/mysensors-v3-3-2-light-switch
For information, a few members have too many PCB of this node that's why if you are living in Vietnam or asia, Nca78 can send you PCB and if you are in france, i can send too (contact by pm for terms).
I use this node since 20 days ago, and it's working well ;)

@tonnerre33
I will be really interested to buy you all the components you would no longer need. NRF, pcb, fuse thermal ... If you agree, can you tell me a list of what you offer thanks -
hello, anyone use this project with home assistant?

Thanks for this. One question about the SSR. Does it matter if its a zero crossing relay or not if just switching lamps with fixed amps? That the difference between the G3MB-202P and G3MB-202PL. I'm not sure which to get.
@Paul-Derbyshire if you're buying on aliexpress at less than 3$ a relay, you're buying chinese clones like most of us here. I doubt they bothered implementing the zero-crossing function on the chinese clones...

Hi,
I love this project. This is almost exactly what I wanted to do by myself (but I have no knowledge in PCB design). As this project shouldn't require much power, have you ever though about using a dropping capacitor PSU (http://www.circuitsgallery.com/2012/07/transformer-less-ac-to-dc-capacitor-power-supply-circuit2.html) instead of the HLK-PM01 ?
If this is a working solution, it would make your project even cheaper.An other question on the DS18B20. Wont the proximity with the relays (heat generators) will disturb the temperature reading ?
