How can we apply the same (getting the feedback) while using the manual swtiches (that take power from home service panel) ?
Thanks
Great project
But I have a question
Agar hamne relay 1 ya 2 ya koi bhi relays ko on kar rakha h via manual switch or electricity jane ke bad dobara ati h to kya vo relay activat hongi jo hamne manually ya blink app se on karke rakhi thi ?
Excellent, thanks bro :)
Thanks
if the power goes out do the switches remember their state? i.e if it was on before power loss do they turn back on on power resume and vice versa?
Amazing product.thanks for sharing.
Welcome
Thanks
Worth trying

sorry, But can you break it down more, if eventually i want to use it for a 220v appliances thanks.... because your diagram show a 5v dc switch
hello, I really liked your project! I tried using the same code for my setup but I’m having trouble with it because Alexa keeps discovering espalexa devices that no longer exist. How can I fix this issue?
you produce such great videos!!, how hard is it to add Blynk into this, as I am converting a camper van project and want Alexa voice control but also use Blynk that allows me to have battery status, solar charge status, turn valves on etc from a central iPhone/iPad screen in Blynk (just learning and your videos are a great help...
. thank you in advance for your help

idont have Alexa speaker can I able to use this code for phone controlling
can I use doorbell switches as push-button?
I have 2 channel relay module which says 5v . I tries using them with esp8266 but it is not working properly. I think because esp32 and 8266 have 3.3v output only... what should I do??? How to use 5v relay with 3.3v ???
If there is no internet even then also the manual switch either works or not
is it compulsory to have echodot to add this switches
a question can be put an esp 8266 instead of an esp 32

Thanku sir wonderfull
Welcome
Does it work with Home Assistant?
I want order pcb with assembly but told me that you want some files is not on like with Gerber file could you please send me it
thanks . but can we do this without echo dot? caz in the video the echo dot was restarted to identify switches. whats the use of echo dot in this project?
Hello, ROK!
I have no Echo Dot. I did this project using the Android app Amazon Alexa and the switches weren't found by the app.
My smartphone and switches are on the same wifi. And I restarted both (smartphone and switches). Alexa coudn't recognize the switches.
Bro how to install library
can you please provide the pcb design please
Thanks for idea😊 does this system remebers it's past state when power goes of and comes back?
No, but soon I will make the same project with Tasmota, there it can remember the previous States
I'm eagerly waiting for that please can u make it..I'm ready with parts to make it for my room😅
How to connect the Google home with same this process instead of alexa
can i use node mcu ?
Can this be done using Google home app also??
is it possible to use latch button? Because I saw in the video that you use pulse button.
Thanks and congrats for the project
In this project, I have used switch not push-button. you can use Latching switch
@@TechStudyCell That's perfect.

Bro alexa+blynk app +manual control home automation video podugha bro
Hi Friend, congratulations from Brazil ! I have one question , if my internet is out I have some option to turn on my ligths?? Something like manual solution ?
If there is no internet then you can control lights from switch manually.
Great video. How to make the lamp automatically turn off after 30 minutes?
Basta colocar como uma tarefa em sua assistente virtual, Alexa ou siri ou Bixbay. Ou seja… coloque: Alexa, acender luz do quarto, desligar após 30 minutos de ligada!
saludos desde argentina.no me conecta a alexa puse la direcion 192.168.1..... y me sale not found espalexa
