Thanks for your feedback...

[@TheFazalrahmanpp]

Thank you very much for this astonishing project explaining in simple way. I was looking for this. Hope to see more from you.

[@TechStudyCell]

Sure... Thanks for the feedback.

Excellent work sir i am Waiting to your alexa video. Using 8 channel relay

[@Kishan010]

I am useing this project since 3months theare Is a error once the wifi is disconnected we have to re start the project can you please fix this by re-codeing

[@dmdago]

That's an spectacular project! You got a new suscriber! By the way, is there any possibility to add analog and digital inputs? So a relay can activate a fan when temperature reaches an specific value? Thanks!

[@rahmantofarrelezra]

Can we use esp 8266 for 8 channel relay?

[@TechStudyCell]

It you connect switches then no.

[@kuangna]

Hi, We do quite similar project. Did you have the problem for long length cable manual swith line? We use telephone line, it's about 10 meters per line, and it sometime tricked their own.

[@vishaljain6130]

really you r good explainer, I appreciate your efforts. Can i see next video of fan speed control within a very short period ? My all wishes with you. I write comment first time as you are very honest in your great job. Thanks.

[@shashivadhangunti3411]

very perfect explination and well working sir

[@TechStudyCell]

Thanks

[@jimmyelectronics2264]

Can I get ready made 8 channel modules for reselling purpose

[@manmeetsinghKJ]

i love your explaining way, you are good explainer, i say.. i love your project, one suggestion, plz add one fan speed control option in this or next video.. i m waiting for this option in your video

[@TechStudyCell]

I have also that plan. But it will make the circuit complex. So trying other alternative way to control the speed.

[@RonenLin]

Super nice board! Do you have a written list of all the parts required for the custom board? Also, will this setup work with Hassio? I was looking for an 8 chan that allows manual switches as well as wifi control.

[@ridhus2290]

Can we use the same code for normal on off switch

[@ayushkedari1566]

Sir during without internet mode , when I turn on switch the relay goes on and off for long while , why is it so

[@abdurahimsalsalani7108]

Is it ok for 24v bulb?

You are welcome

[@ChandanKumar-kr2kj]

Wifi does not connect half of the time. Can you please include code in loop to keep checking wifi status to connect automatically without turning off and on esp32?

[@mozquito76]

This is awesome, but - do you have also the same .ino for the WEMOS D1 R2 ESP8266 Mini?

[@NEWBI3GAM1NG]

how about using firebase instead of bynk app.. but same function with manual push button.. is it possible? thanks in advance

[@jeanten3059]

Sir you are doing great job, but I curious .. what if one of those communication between blynk app and device suddenly disconnected , is that the device and or blynk app knows last state of each channel after reconnect or connection establish ?? hope you understand what I mean. thanks

[@JonatanCastro-secondary]

Excellent video, thanks for creating it. Am I assuming correctly that in the arduino sketch you are also "linking" the push buttons to the relays? So when you press push button 1 it turns on relay 1, right?

[@TechStudyCell]

Yes, correct.

[@Abu-Saleh]

Does it synchronise after load shedding? I have made this type of product with esp8266. but there is a problem that, after a load shedding when esp board re start. All switch are turn on.

Hi Sir, How do you control the speed of the fan using blynk and manual fan regulator. Can you make a separate video how to do it.

[@saikalyanmishra21]

It's easy to control 9 with esp8266 Any Idea to increase the relays to work as ac appliances switch?

[@joshitoshi9835]

why dont u use ttp223 capacitive touch/push buttons? they are more suitable and look modern in this kind of projects, do u think they are not usable or sustainable?

hello nice project, I tried and connected a switch with one end to gnd of esp32 and another end to pin d4 and for relay 8 to pin 26, if I use it with app and wifi it works great but when I try to use switch to turn ON the relay is turning on and off continuously can you help please. Where I'm I going wrong here can you explain.

serial monitor output the relay keeps on toggling automatically when used switch else with app it works 21:27:03.632 -> WiFi Connected 21:27:03.836 -> Device8 ON 21:27:03.937 -> WiFi Connected 21:27:04.140 -> Device8 OFF 21:27:04.241 -> WiFi Connected 21:27:04.443 -> Device8 ON 21:27:04.543 -> WiFi Connected 21:27:04.744 -> Device8 OFF

It is less than ideal as some of the GPIOs are high for 100ms or so, after restart. It would be good if you use a port expander something like MCP23017 to solve that problem. Preferably with cheap Wemos D1 mini.
