💬 AC-DC double solid state relay module

[tonnerre33]

@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.

I'm going to do these for my light switches but what should I use for in wall on off switch without relay?

The link to to DirtyPCBs is broken, got a new one?

[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!!!

[laster13]

@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.

[HaM]

@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

[rhapen]

@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!!
