DIY Smart Distribution Board with Wi-Fi | IoT Arduino Project

How to make a smart distribution board with Wi-Fi and display.
It can measure voltage, power, current, frequency, power factor, energy, and temperature and sends data to the internet.
It uses ESP8266 and can be programmed just like an Arduino.
Power measurements are done by PZEM-004T-100A v3.0

The use of silicone adhesive around electronics is not recommended since it emits acetic acid as it cures which will eat away at copper conductors. If you must use silicone find a source for silicone adhesive that is for aquarium construction. It has very little emission of corrosive off gassing.

This is awesome. I would recommend adding a battery keep the esp online for at least a few hours after power is turned off to be able to tell the difference between a bad wifi connection and a power-off event.

Awesome project, but be careful with soldered wires in screw terminals. Under sustained pressure the solder deforms and becomes loose over time. Here in Hungary it is also against the code to solder any wires installed in buildings. It's a fire hazard.

It looks nice but this design would probably not be anywhere close to being regulatory compliant here in the UK or anywhere which uses British Standards (e.g. BS1363) such as Ireland, Hong Kong, Singapore, Malta or much of Africa (e.g. Botswana).

I do however think that you should've connected each breaker terminal via a busbar instead of a thick cable with the insulation stripped so that it can connect to the busbar but since you did it this way, you could've at least not left any bare metal exposed, i.e. it looks like some of the cables are not fully inside of the breaker.
It might of also been worth only using RCD breakers for added safety and installing a socket inside the breaker board (like what is done with CEE 7/3 and CEE 7/5 EU [socket] standards) either connected to it's own breaker or an existing circuit...

Very ingenious.
but do not try in the UK as it will not meet BS7671 wiring regulations and will invalidate your home insurance.
It will also render you liable to prosecution unless you are an approved Building regulation Part P contractor.

I built nearly the same. One ESP board, one Max485 ic and a rs485 meter. A little bit of code and it works since one year 😊

It is mini SCADA programme for lighting and power distribution board including energy management and monitoring.
Everything is right except standards, , workmanship and management the wires of control, communication and monitor module.Either there should be a seperate segment for ELV circuit or additional door for avoiding entanglement with LV wires.

The wire used to feed the circuit breakers is way too small. You will burn your house down if your not carefull

[quadlawnmowerman]

WOW, super illegal and unsafe, what a major fire hazard.... DO NOT FOLLOW THIS ADVICE!

Takes a special kind of stupid to solder cable going into a terminal block or to hot glue exposed circuit boards in place shows you have no idea what you are doing...

[sygad]

The cables entering into the circuit breakers need to be ferruled. Good idea for a project.

I still don't understand much about electrical power, but I'm manufacturing a CNC Router, it still has the whole system from protection to electrical I am a system designer and developer
for me it doesn't make sense to buy a bunch of equipment from different manufacturers to control a simple on and off and logic which is involved in protecting the electrical network and also protecting the CNC control electronics.... But I see that it is possible to do the same as you did in this video, of course adapting it to the universe of the CNC Control Box... .. I'll watch your video many times and see what I learn here on the channel to try to develop this!

[KiwiGoneDutch]

This is a really bad idea. You're using a safety device for a switch. Instead, use a contactor. And have the electronics in a separate enclosure.

[DmitriyKhazansky]

Tripping that CB that way is asking for trouble. Breakers have a purpose built device called a shunt trip that does this very thing. It would have been nice to power your ESP from the line side of your main so it stayed on all the time. Then you could add a shunt close which you could use to turn the breaker on through the ESP.

[janklas]

People please do not do this, unless you want your house to burn down.

Build whatever smart home shit you like, but NOT in your distribution board.

[shaunclarke]

Wire connections in screw terminals also should not be soldered.

[alunroberts]

That is so unsafe in so many ways. You could have made a unit that plugs into your consumer unit using a contact transformer. And a relay to trip the RCD if you wish to. But what is the point of it all you can not switch it on again.

[legominimovieproductions]

And no, they can not handle 2000 volts magically, with 2kV the voltage would easily jump from solderpad to solderpad

[srfrg]

I have no idea which country you live in, but in mine it's not good practice to put low current hardware in the mains circuit breaker box. We rather use two separate boxes, one for the high current and one for the low current, allowing only low current probes to live in the high current box.

[legominimovieproductions]

This creation is a fire hazard, life risk and over all a good idea with the worst execution possible

[djnor]

Nice project, but i would NEVER install any low voltage sensible electronics inside the fuse box without proper insulating housing ...
And hot melt glue / silicone "glue" is not a way to fix things, you need something more robust and durable. (Metal strips, screws ...)
But working good for now, i am planning to implement some zigbee based monitorint for individual sockets / modules in our shop to monitor the power consumption of our fridges / freezers and also to check their temperature, and enable them as thermostats to precisely control their temperature as well. (And also to apply an automatic deicer function during the nights to get rid of the ice buildup in our showcase fridges)
