hello a query can do this but with 2 esp32 without being asked for wifi passwords

[@kevinedward4108]

Hey, I Have A Problem. So The ESP8266 Just Dosent work. The Serial moniter Says: 15:07:09.541 -> Blynk Not Connected 15:07:11.544 -> Blynk Not Connected 15:07:13.542 -> Blynk Not Connected 15:07:15.569 -> Blynk Not Connected 15:07:17.564 -> Blynk Not Connected 15:07:19.567 -> Blynk Not Connected 15:07:21.563 -> Blynk Not Connected 15:07:23.562 -> Blynk Not Connected 15:07:25.553 -> Blynk Not Connected 15:07:27.561 -> Blynk Not Connected 15:07:29.561 -> Blynk Not Connected

Thanks for the feedback.

Really it is a great opportunity for me to start watching ur valuable channel & wishing u all success.

Hi there, I am a big fan of you and watch your every video for almost 4 years. I appreciate your hard work and effort behind your all projects. I have seen more than one year, you do a lot of jobs behind home automation projects based on Blynk and another platform. It is very much appreciable. If you add a digital fan regulator with those home automation projects controlled by the Blynk app then it will be a great achievement for home automation. we see some beautiful good-looking sonoff or another wifi-based Chinese Fan regulator with touch switch panels which can be controlled by both App and touch panel switch (or physical buttons when the internet is not available) to control fan speed. still, now no KZbinr/project maker makes such this type (physical Touch Panel+Zero Crossing Ckt+Blynk app) of project. As a fan, I hope you will make this for adding your existing home automating project and will give that project (full home automation)as a gift to your viewers if you have time.

confused between nodemcu CP2102($300) and CH340($235).....which one to go? can use the cheaper one??? are those function as same

Very nice video. Can you suggest me what is the cheapest microcontroller that I can use for my IoT project? I need to connect with it through a SIM module. What is the best SIM module that will work perfectly with Indian SIM card? Thanks in advance.

i have completed the project its working but there is an issue that relays are turning on when switches are of and turning off when switches are on from both sides manual switches as well as from blynk app.... any one can help me here?

[@nimeshsasinu1483]

why isn't my esp32 wont connect to wifi ?, please help i did as the video shows.

[@geniodachianaok8384]

do you know if there is a way to made a button shortcut on my cell phone out of blynk (withouth launcing it)

[@Golobtin]

Hi and thanks for the video. I was wondering if it would be possible to use the sort of technilogy you are using to push a button on my mobile phone to activate horn or a buzzer on my car providing the car has no internet service to it. Say the car is parked in a large paking lot and l need to find it. Cheers

[@4uhacks767]

@Tech StudyCell sir what do I need to change in sketch to use touch switch using tp223 instead of push button?

[@user-vd3qd6ne4d]

Hi friend! Can you make video and introduce this idea: in room N1 we have temperature sensor (DHT) connected to esp32, which is sending data to blynk server. other controller which is connected to the same blynk server and controlling relay using temperature measurements from room N1

Hi bro can we use any other pins than D3 so we don't need to worry if the pin is grounded or not for the node mcu to boot. Can we use D4 instead of D3?

[@TechStudyCell]

You can. But D4 has its own limitations. It is better to use ESP32

[@basilbinu4933]

@@TechStudyCell I tried using D4 but same problem.Board wont start when D4 is low. Then i tried another pins and my configurations are. Relay D0,D1,D2,D3 Binary Sensing RX,D7,D6,SDD3 So far i have not been facing any issue while booting with all input pins grounded or any other issues while running. Is this ok to be used for long time.

[@sameerali7763]

Here's my small doubt , Why are you (and also other KZbinrs) limiting the project to only a few modes of operation? Like wifi+manual (no infrared & no Bluetooth control & no voice assistant ) Wifi+manual+infrared (no Bluetooth) What is the limitation here? Please clarify.. I'm trying to make it for my home And i need as many controls as possible Please reply soon 🙏🏻🙏🏻
