The device of an Engineer, not a marketer! perfect!
for automation DIYer
FINALLY! an ethernet energy monitor!!!
yes, i prefer wired solution, such as ethernet.
how to avail?
You're simply an artist. I still have one of your first products and I'm very happy to see you're working hard to deliver more and more nice innovative DYI-like solutions. Thank you!
thanks,We constantly innovate.
Incredible, that's what i'm looking for!
Very nice board. I will wait to buy a Version 2 if these modifications are made:
- not so big board (tall) (maybe by removing LCD and SD)
- integrate voltage reading
-optional jack or screw terminal so the jack does not use up so much space
You do great products and hope to buy in the near future in a version 2.😊
when have news , we will upload to our youtube channel
Interesting product
Very interesting product
thanks
So for power (watts) we would need to duplicate the example for each channel like you did in Channel 1 right? Other than that it should be no tuning? What about CT clamps with burden resistors?
yes, you are right. just maybe need calibration for every channel is better. what's your mean about "What about CT clamps with burden resistors"?
Now that iotawatt is stopping production you should start to become one of the dominant players. Your main competitor would be Emporia as it too has 16 channels. Only wish it was more affordable in Australia.
maybe we will design 32 channel version.
this is precisely what i was missing for my home metering :D is there any din rail mountable ct clamp? maybe multi channel?
cheers
board have plastic shell can install to DIN RAIL, CT clamp not need to use DIN RAIL.
Great job, do you have voltage measuremt, to calculate the power factor bettween curent and voltage?
now the V2 PCB under desinging, will include voltage measurement.
Nice,it Will works on 220v 50hz?
@@sebseb319 yes
This module is very suitable for calculating the percentage of load in smart homes. It will help us identify which object is consuming the most energy
You have measured the current intensity. To calculate the power consumption, we need to have the voltage, current frequency, and power factor. I'm looking forward to an update from you.
M16 board mainly use for monitor current. there is a way, install a modbus energy meter to detect real time voltage and power factor. so that in ESPHome , just use real time voltage * M16's current = power value.
@ KinCony IoT Does it show up in "energy"? in home assistant
sure
waiting for kcs firmware for this board , when will be it be published?
now not sure. download ESPHome also is enough use for M16 board.
How do I calibrate the sensors so they can start at zero when there nothing connected to it?
Calibration using multiple known loads
hello pro , What kind of chip do you use to load the code?
esp32-wroom-32ue
does this work with home assistant energy dashboard?
yes, it can support, but i have not tested.
Amazing amount of 220V measurements...I will sell my Shelly again 😂
haha
Don't hurry EM/3EM has real-time voltage monitoring ;)
@@valentinene well, with 1h curve in app....sucks
Nice! Any possibility to us PoE to power it up?
you can add POE adapter
@@KinCony I've a router with PoE, just wondering if it could be powered up from PoE ethernet cable instead of the DC 12-24v
@@garbi8526 now M16 not have POE function, if you want to use, need add another POE adapter will be ok.
Nice work!! But we need voltage measurements. Preferable 3, for 3 phase systems.
Due to time differences (and an extra device) i am afraid that power / pf measurements are incorrect.
yes, we will save your suggestion.
@@KinCony plus 1. If you would implement this I would buy in an instant!
@@bwout1987 do you think add 1 channel voltage detect or 16 channel? maybe all channel's voltage is same.
@@KinCony 3 channels would be ideal! And it would be absolutely amazing if there were jumpers to select which phase the channel is.
@@bwout1987 can you say details about "jumpers to select which phase"?
how long can the clamp cables be ?
not too long, usually 1.5 meter.
What is the measurement update frequency?
it's set by yourself in ESPHome.
N1!!
is there a Schematic available
yes, the hardware is open source. you can download schematic from kincony webpage
It comes with CT?
no, not included CT sensor.
Where will we give 230 voltage input
sure, 230v or 380v , just chose correct CT clamp sensor
Can we input voltage also for Power measure
@@nikhilps5234 sure, you can use voltage*current=power set in ESPHome.
can use for dc current?
no, only use for AC current
Super! This device can mesure in positive and négative? I mean for solar injection.
this is for AC power.
My question was not accurate.
Yes after the inverter the current is AC but we can have a positive or negative curent. To know if we inject or buy electricity the measure is absolute or with a sign+- ?
@@sebseb319 this board only use for test AC power, not for DC power. if you want to test DC power, you can chose any our other board, just use by digital input port is ok. then convert your DC power to a TTL level signal or 12V or 0V signal.
Add a voltage meter an I buy some
i think every channel voltage is same. you can know the voltage by other meter.
Can it work with Node Red?
you can write arduino code for mqtt function work with Node-Red
@@KinCony I can't write this code, can you write this code for connect with node-red with MQTT?
@@ivaylomanolov1455 maybe in furture we can do that.
My board is not measuring any load
please post your question details to our forum: www.kincony.com/forum
Too bad you didn't add the electronics to monitor in real-time the value of line voltage and also the power factor which can make a huge difference between real power consumption vs this estimation
M16 board mainly use for monitor current. there is a way, install a modbus energy meter to detect real time voltage and power factor. so that in ESPHome , just use real time voltage * M16's current = power value.
@@KinConythat’s right, you can use that workaround but then your solution is way more expensive than the Emporia similar product
@@valentinene :) it's different.
Are the 3 analogue inputs suitable for accurate voltage measurements (3phases), or do you need a specialised DAC /power meter chip for that ?
@@gubbernl 3*analog input use for dc 0-5v signal. yes, specialised DAC /power meter chip for that, if want to read ac load's voltage.
Hello , Can you share arduino ide code for this board?
code in our forum
@@KinCony But Arduino code not available.
@@selva9300 there is SD card read/write arduimo code. if you want read CT sensor data, we will upload arduino demo source code to forum later.
@@KinCony Thanks for replay, Waiting for CT Sensor demo code in arduino.
Price plz
you can see video description, here have order link
Looks like a great product, but I would definitely make a video in English.
yes, already have video tour about it: th-cam.com/video/12f4BwN_SKw/w-d-xo.html
@@KinCony I see. Does it work when the clamps are on different phases? For example three clamps on L2 and two clamps on L3?
@@wrnrt here is new video of M16v2, support voltage detect, it can use for L1,L2,L3 : th-cam.com/video/BSDqcjNImME/w-d-xo.html
Make it 4ch mini version also
but pcb size just smaller a little.
Shame it's too expensive!
