Learning & discovering new things can enrich humanity. Technology can definitely change the world. I like to search problems so that I can find solutions. I don't realise my passion about technology during my child hood but yup now I did, & like to encourage others to follow their passion, their dreams. Teaching technology facts to community is my dream. But for that I have to learn everything about what I want to teach.
I'm using this meter, but when Comm setting to RTFT meter sends reading in sums not real like, until reading kWh reaches 32kWh only then meters updates the next reading. and do not update +1 or +2 kWh o MODBUS.
@@TechnoAutomation So in meter settings I set COMM : RTFT And now meter reading is +4194kWh ESP32 keep reads 4194 until sudden +32 I.e. 4227. Then again it start keep reading 4227 for a while. Then sudden 4260 (~+32). Reading on Meter is increasing gradually but ESP32 somehow reads when sum is +32. When I checked the data earlier 4194 kWh. the interval was 16kWh.
hi, i know its been 5 years ago. I want to do the same but instead of removing RGB led driver i want to keep it and try to decode/encode IR signal with a ESP8266. would you mind to give me some advice on that?
You can flash esp with tasmota ir firmware and connect ir receive led output pin to esp 8266 input pin. Assign that pin as ir receiver in tasmota firmware. Once this procedure is completed you can read ir recieved data in the tasmota web console. Recieved data encoding done by tasmota firmware out of the box. You also can pass encoded data to mqtt broker for further connectivity. I know it's completed but if you start , it will become easy. First tym tasmota firmware. It's easy to install and understand & good community support on social media and strong documentation on its repository.
I want to a make a home automation for my home. So that I am decide to control all the bulbs and fans through the home assistant or phone. I am not connect all relays and senaor through the wifi network because my home is big. Wifi range is to small for my home automation. So that I am decide to implement modbus for connect all relays and sensor. I thing Modbus is more reliable and easy to implement because the wired connection. I want to connect 10 node. Each nodes contains or hold the few relays and some sensor such as temp and humidity CT sensors mmwave sensor motion sensor. And each nodes connect through each other. And last node is finally connected to think client or Ressbery pi which is operated home assistant os. Please solve my problem and give the feedback
Modbus is a master slave communication protocol. Each node will not talk to each other directly. Only the server can talk to all devices. For home automation wifi network is the best suitable communication method. If your wife's network is limited in range then you can use wifi repeaters. Or you can use esp now which is a light weight wifi communication protocol which provides mesh networking and nodes to nodes can talk to each other.
This is very informative video, can you please tell how to write the value from the microcontroller to other devices if it have both r/w holding register.
Your videos are really useful but why are you not posting videos like creating webserver and configuring MQTT sorry since its are the hot topics. I accidently got your channel Its very informative. Please post the videos on configuring servers and getting data from MQTT and displaying them in dashboard also dashboard creation. This will be really useful for all. its my request
if x_medium < x_center - x_band: x_position -= 1 elif x_medium > x_center + x_band: x_position += 1 This part of code smoothens servo motion. SG90 has a resolution of 1deg. Hence we get 180 small steps to move from 0 to 180. We can't get an intermediate position so little gitter will always be there.
Hey Ashish great video you made i am interested in doing some work for a project together with you. If you are up for more information please contact me 🎉
Hello sir, thank you for the great video. I have a question, I'm working on a project that requires to track an object by selecting it. Is there any tips that you can help me with to take the first step in it?. Thank you for your time, have a great day.
You can use colour masking based object detection if your targeted object has a unique colour. If it's not possible then you have to use a ai based tool which is much more complex to implement.
Excellent video sir, can you please explain how to connect more meters and how many esp module required if we need to connect more meters. And please can you share your contact no or mail I'd. Thank you.
This is a great tutorial. Very well done and the clear explanation about The voltage levels for different electrical standards was spot on. Cheers my friend. Well done!
Actually I didn't get enough time to make content due to my job. I wish to make another video on top of this for displaying data on webpage and forwarding data to mqtt . I hope I will get enough time to make it.
Hi I your code worked really well with my single phase smart meter DDSU666-H but I am having trouble making it work with a three-phase smart meter DTSU666. I am constantly getting a 0xE4 response code. Any help would be appreciated. Thank you
@@TechnoAutomation Did you use same esp8266 code? I have to read five energy meters which will be connected in daisy chain, let's say address 1 to 5. I want to read data from all 5 from a PC which will be connected on the same wifi router where esp8266 will be connected. One question here, what we call this esp8266, gateway or slave or master?
Hi Sir Thank you for a codes and related your presentation. Can I do the same with other meter like selec MF383A.Also one more thing about MAX485 to TTL converter, can you suggest a make or resources.
Any modbus slave data can be read by this method. & Max485 - TTL you can buy from Amazon or any other suppliers. These days there are plenty of breakout birds available in the market. Make sure you purchase 3 of them so you can have spare in case any one failed..
How can I use another algorithm to find and track another point? I'm trying to track a drone in the sky, how do I do this? I'm also trying to have a drone plane chase the other drone, so the servos will be used to control the Ailerons
What you are trying to achieve is only possible by using AI. Color detection is not good enough for that. I think you can detect specific object using Edge impulse. It's very powerful tool which used tinyml algorithm in backend for data processing & lots of tutorial are available on internet. docs.edgeimpulse.com/docs/development-platforms/fully-supported-development-boards
Bootloader is small piece of code which allows you to re-flash microcontroller using serial interface. Example:- you can program Arduino Uno using its serial rx,tx pins without much effort. But if you have Arduino Uno without bootloader then you need to program it using ICSP. In Circuit Serial Programming. If you have Arduino Uno without bootloader and you download blink program using ICSP it will start blinking led. But you can not reprogram it using serial port as there is no bootloader in it. Case B :- if you download bootloader in your Arduino using ICSP first then you need not to use ICSP to flesh new code. You can use serial port to re-flash it. I think I answered your question.
Can the max485 run off 3.3v? Been struggling with for a week without any luck. Even with to esp32s. One as master and one as slave. I have been using 5v and direct to the pins of the esp which I assume might be the problem
Esp32 & 8266 is 3.3V board. If you have used 5V for Max485 then signals from 485 module is 5 V pulse. In that case you have to used voltage level shifter or Potential devider to protect ESP32 or 8266. I have tried 3.3v Max485 & 232 board which makes voltage level compatible for esp. I have also tried 5V operated Max485 with esp8266. In This case I have used potential devider for RX pin of esp8266. Tx pin of ESP can directly connected with Max485 converter. Voltage level shifter parform best if you have Different voltage operated device.
@@TechnoAutomation LED stripe, i found the issue, i forgot to use 10k resistor on gate to ground, thats why those fets are not turning off completly, i had to replace with new fets with 10k resistor
Assalam o allikum brother. I have a 18kw vfd now i am only able to on and off the vfd using esp8266 module. I want to see the vfd lcd wirelessly on my android
Similar project i did for energy reading display using webpage. You can refer below mentioned code github.com/ashish8284/ESP8266_MODBUS_GATEWAY_GROWATT Webpage.h is for creating webpage
Hi Ashish, I Am currently working on something similar to the video. I am using an Arduino mega for communication between the meter and the Arduino board. But I am facing some errors in the serial monitor as it displays some garbage values in it. Can you help me with it?
