You should have used Optocoupler for isolation

[@Elfnetdesigns]

I agree. And there should be mounting and earthing options as well.. Who am I kidding, earthing is a myth in India and other similar countries..

[@trevorslab]

Also should have put HV isolation paths under the relays and connectors

[@mylanthony]

@@trevorslab My thinking... usually HV traces are blank and well covered in solder... spacing is too small as well .... so I cant believe this one is safe... well... not for strict western regions at least

[@Elfnetdesigns]

Yeah, no isolation, and those relays are way too small for any real world load switching. In reality you do not need all those relays when you can use properly rated power transistors which will reduce overall power consumption and the need for a snubber network / diode. You can in turn use the transistors to switch solid state HVAC relays which can handle real world loads like an entire lighting section, air conditioners and other moderate to high current appliances even switch your main city power on and off or between solar or generator power and mains city supply. make the system usable to a realistic degree.. Those tiny relays on board will only introduce a possible fire hazard into your home if you over load the circuit. Modify your PCBs to have line isolation and mounting options and earthing provisions so people in countries that have actual electrical codes that are enforced can actually use it legally and safely. Also this is in no way automation, this is simply over the net remote control and you do not need fancy apps on a smartphone to do this. a simple webserver arduino code with some HTML code in it loaded straight into an ESP module and all you need is a device that can connect to wifi and has a browser and you are in business. I can take your whole project and reduce it's size over half and make it NEC compliant for use in the US all while making it capable of controlling high current loads with no mechanical relays on the main PCB at all.. Automation would be having circuits on a timer like a sprinkler system at home or on a day/night sensor to turn lights on and off..

[@Thuliolima2008]

So show us what you can do.

[@Elfnetdesigns]

@@Thuliolima2008 I myself do not have to show you when all you have to do is look up any 1st world based system that is properly installed and being used in places where electrical codes are known and enforced.. Look at the many many other IOT based systems sold under big name brands and installed in places in Canada, The USA, the UK, etc... That is what 1st world developers can do..

[@back_to_momblackburn8580]

Perhaps you should do a bit of research before spitting on someone's work. Your point about true automation is correct, this has no brain, so to speak, and is thus not true automation. This hardware package could, however, be used for true automation with no modification, simply different code. That being said, this is where you stop being right. The transistors he is using are, in fact, correctly rated for this application. Transistor rating also has nothing to do with the snubber diode, which is designed to snub (thus the name) the back voltage produced by the relay coil turning off. Any proper circuit which uses a mechanical relay will have such a diode or equivalent protection system, changing the transistor does not eliminate the need for this. Your comment seems to indicate that the relays could he replaced by high power transistors, but that's such a ridiculous idea that I'm going to assume that's not what you meant. Maybe you meant use the high power transistors to drive a SSR, but that's unnecessary. Small transistors like the ones he has are perfectly capable of driving even very large SSRs, and actually, for the size SSRs used in home automation, the NodeMCU itself could directly drive them. As for the size issue, I don't know if you've ever seen a SSR, but they are typically larger than their mechanical counterparts. That being said, I'm sure if you went with the most expensive, modern SSRs you could find, it would be significantly smaller. It would probably also be 100x more expensive, but since you're a rich guy in the 1st world that shouldn't be an issue for you. And just FYI, most '1st world systems' use mechanical relays, snubber diodes (usually TVS), and a transistor based driver circuit very similar to the one used here.

[@josefaschwanden1502]

@@back_to_momblackburn8580 use a fuckin bta-16 is probably what he meant, it isnt a transistor but the closest thing to one.

[@ahmadseblini5184]

​ ElfNet Designs "That is what 1st world developers can do" : You are a proud man, good for you keep up this community spirit . This video showed you the essentials, it has all the parts to make home automation, so you can customize it (or built it to your code). I ve replicated it and it is working fine with all the automation rules (dependencies and timing) that I needed and only 8 relays (upgraded to 25A relays for AC, heaters etc.. block relays with isolation so didnt use the video circuitry) but couldnt do it without the support of such videos.

Control over WIFI/Bluetooth, by Android app(which I can develop) 5. 1 Speaker with MicoSD mp3 audio in it (MAX98357A/SD car reader) Can I use ESP32 for these all or do I have to buy other chips as well ?

[@meeskees4227]

If you can use arduino for it, it will work even better with esp32 because its faster and better specs. It does have a 3.3v output instead of 5v and it can only supply like 30ma instead of the like 80ma of the arduino so u might need the uln2803 chip that is a 8bit transistor array.

Hi, very nice proyect, I just wanto to add the relays dont have the necessary insulation and electric shielding for this to work properly, a single diode is less than suficient, I would like suggest the use; An insulated ouput, like the diigtal pin to a UNL2003 to avoid vcc peaks, and then a of a snubber and a varistor on each relay output.
