110v-230v AC to Mysensors PCB board

[sundberg84]

HLK spec. is max input of 0.2a with small spikes tolerance to 1.0A. I also ran out of 0.3 but are now using 0.2a and that works fine.

Does the light switch need to be a SPST or can you use a pushbutton? Curious how this would work with a SPST switch. I haven't looked at the code to see what is setup.

SPST

This depends on the sketch you flash. ;)

Hi,

I understand that the question has already been asked, but ... Is there a possibility to adjust the scheme to the ESP8266 instead of Arduino? Anybody can tell or help - how to do it?

Regards,
Nikolay

[jemish]

yes, now how to use ESP8266 instead of arduino for the same function that we are discuss in this topics.

Hey Guys,
I am working on ESP8266 as well. But I am newbie to electronic designs. But in my view it should be silmple and we can replace Arduino nano with ESP8266 and remove NRF module.

One diagram and circuit is explained here http://iot-playground.com/blog/2-uncategorised/77-esp8266-internet-controlled-switch-easyiot-cloud-mqtt-api#materials

@csa02221862 you can use this cercuit with SPST buttons. But Switch will notbe connected to mains. It will be conneted to ESP8266 GPIO of (or arduino). And in Sketch (i.e code ) you have to write code based on GPIO when ever it goes 0 to 1 or 1 to 0 Relay state shoud be toggled.

I hope I make sense

@aproxx you did great job here.

I am looking to reduce its size more if possible and wish to use ESP8266. Also looking to add more then one relays to the board. In some rooms there are 3 buttons on one panel. So thinking to use 3 relays. Will it be a good Idea? I think should not matter as long as I have enough GPIO to control relays and Electric wire connectors can bear the load.

[jemish]

yes , I also thinking to use more than one relay.

Found something interesting on Aliexpress which is a drop in replacement for the HLK-PM01:

the HLK-PM03

Same size and pin locations, but 110-200 V AC to 3V3 DC.

It fits my multi-power options board perfectly.

[toabhishekverma]

Nice find GertSanders ... I am planning to use esp8266 which runs on 3.3 volt... best fit ..

If we use this we may have to drop few things from 5.5 board right?
Like no need of 5v - 3.3 converter
change relay to match 3.3v like this http://vod.ebay.com/vod/FetchOrderDetails?qu=1&itemid=401045943120&transid=522355020027&viewpaymentstatus=

Anyexpert around? do we need to remove anythingelse (any capacitor?)

[toabhishekverma]

But 3.3v relay will not match the board. If we use 5.5v relay do we need to add something to circuit?

Hi,

Thank you for this pcb. In which program did you do the design? Do you think you can share an editable version of the design?

I would like to modify it to accept the Mean Well IRM-05-5 instead of the Hi-Link.
It is more expensive and bigger AC-DC circuit but since I hace some in my stash i would like to use them.

That's a link to your shopping cart, we don't have access to...
I'm interested in the relay, can you post a working link?

[toabhishekverma]

oops..

here is the link

[GertSanders]

I use the same SONGLE relays:

[toabhishekverma]

@GertSanders thanks for this link.
So do you have working prototype? what board are you using? I am in middle of finalising components and trying to finalise design. With little knowledge of electronics my progress is slow.
Also for 220 to 3.3v there is another converter from Olimex https://www.olimex.com/Products/Power/PWR-90-240V-3.3V0.8A/
overall its abit smaller then Hi-Link... Hi-Link abit better because all covered and less dangerous.

Please share if you have any design finalised.

[Yveaux]

@GertSanders @toabhishekverma Do you have the dimensions and/or holding resistance?

[toabhishekverma]

Sorry I didnt get your questions .. do you mean dimensions of 220-3.3v converter. Here they are.
output 2.5W 3.3V/0.8A +-0.2V size: 30x20x18mm

I am not from electronics background so didn't get what holding resistance means?

[Yveaux]

@toabhishekverma No, I meant for the relay ;-)
What's the resistance of the 3V coil? I want to know the current flowing when the relay is active.

[toabhishekverma]

@Yveaux Still no idea about it. Check link if you get something from it. what I know is it can bear up to 10A current and can be controlled using 3v .... my order still in shipping so don't know more then that.

[Yveaux]

@toabhishekverma Ah, ok. Didn't know they were still in transit.
Maybe @GertSanders has them 'on stock'?
