💬 AC-DC double solid state relay module

[tonnerre33]

@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 ;)

Hi everyone.
I can not find anywhere Slow Blow Fuse (250v 0.2A). Does anyone has an available link??
Thanks in advance.

[johnym30]

Never mind, got them. thank you!!!

@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

[chickey]

If anyone in the UK is after boards/parts i have spares.

[Rodolfo Vieira]

hello, anyone use this project with home assistant?

[proddy]

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.

[Nca78]

@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 ?

[Nca78]

Hello !
Transformerless design means there is not isolation between main voltage and low voltage parts. You can get electrocuted with 110/220V when touching the low voltage side. It means it can be used only in the case of a sealed box.

For the temperature sensor the main source of heat is the hlk that heats up a lot. It's purpose is not to sense the temperature in the room, but to monitor the temperature inside the sensor and make sure there is not problem with the hlk overheating.

@Nca78 Thanks for the advice.

Would it be possible tot change the relays to one (or two) triacs, keeping it's current features and also allowing it to dim lights?

[rhapen]

anyone found the Slow Blow Fuse (250v 0.2A) on aliexpress? if yes please link.

[rhapen]

found 250V 0.25A o aliexpress - i believe this will be good enough - http://tiny.cc/h4fpiy

@Sacha-Telgenhof : It also took me bit of time. It is the PINs on the board 7 GND 4 for two switches 7 and 4 are the digital inputs on arduino.

[Jose Simoes]

hey @Aproxx, nice project, do you think a current sensor could be added to the PCB to monitor electrical consumption. the idea of adding triact to the circuit by @overlordt seems to work theoretically.

[SensibleHeat]

My parts are on the way and I"m looking forward to trying this one out. Thanks for sharing this project!!

If you create a new version, could you connect the other 2 5V and GND holes next to D6 so these can easily be used as power output?

[Marco Lo Grasso]

I can't understand (scrub here) how to wire the regular light switch to the board.
Supposing I want to use only one relay, I have to wire the switch to the 7 PIN and GND right?

[tonnerre33]

@Marco-Lo-Grasso said in 💬 AC-DC double solid state relay module:

Yes you have to do this, but i don't know if the sketch is working fine with the light switch ;) I haven't tested this feature yet.

Caution, the light switch don't be connected to the 230V !
