  • In this IoT project, I have shown how to make Alexa home automation project with manual switches using NodeMCU or ESP8266 and relay module. With this internet of things project, you can control 4 home appliances from Alexa and manual switches with and without internet. So this is a very useful homemade IoT based home automation system that you can easily make with NodeMCU, Relay Module, Push Buttons, and Alexa Echo Dot devices.
    For this Alexa smart home project, I have not used any custom design PCB or any third-party IoT Apps. I have used Amazon Alexa App to connect NodeMCU with Alexa Echo Dot, so after watching this tutorial video you can make this useful NodeMCU project at home.

    Download Code for this Alexa home automation project from the following article
    iotcircuithub.com/alexa-home-...
    Required components for this project from amazon.com (Affiliate link):
    1. NodeMCU amzn.to/2WoR2A2
    2. 4-channel Relay Module (5V) amzn.to/3r2HuJ4
    3. Push Buttons
    4. Alexa Echo Dot Smart Speaker amzn.to/37sSd84
    Required components for this project from amazon.in (Affiliate link):
    1. NodeMCU amzn.to/3fJA4EG
    2. 4-channel Relay Module (5V) amzn.to/2BQ5Y3o
    3. Push Buttons
    4. Alexa Echo Dot Smart Speaker amzn.to/2PkTOTe
    During the video, I have shared the circuit and code for this IoT project. So after watching the complete tutorial video you can easily make this ESP8266 Alexa smart home project.
    There is a limitation, the NodeMCU, and the echo dot smart speaker should be connected with the same wifi network.
    Soon I will publish the complete article on my website and share the link here.
    If you face any issue please let me know in the comment section.

    This project is awsome, It does however take a couple of tries to get Alexa to discover the device. I have a slight issue in that if you switch the relays on/off change the current state with the push button, the status change is not reflected in alexa. Any constructive input is very welcome.

    Hi Im really liked your project, I put it in two different places and it works normally. But this week I believe that there was an update to the echo dot 4 generation, so my two projects no longer find the devices. Already updated the libraries, restarted the two Alexas which are in different locations with different networks.
    Today I took the same codes and recorded them in other nodemcu and didn’t find anything else. Have you caught more cases like this? Hugs.

    Thanks for the tutorial. I have already requested and i am again requesting for a detailed video on SAFE wireless 220ac solenoid water pump control system with water level and manual on/off button and that with 12v relay. All the videos available on youtube are with wired system which is not practical in most cases bcoz tank is usually at 3rd or 4th floor so running wires is tedious in that case. So please take a time and make one. Thanks

    • @joshitoshi9835
      @joshitoshi9835 3 ปีที่แล้ว +1

      @@TechStudyCell Thanks for swift response and waiting eagerly for that video. Here are some points and specs to note:
      - Working voltage should be 12v dc
      - 12v dc relay must be capable of controlling 2hp solenoid pump
      - Must have water level indicator in terms of leds or 7 segment or small display screen.
      - Must have Manual switch to turn on/off motor at any time (can be further connected with ESP8266 relay to on/off with mobile phone)
      - 433Mhz RF module can be used as its cheap and its range is more than enough in my opinion but you can use any other module which you think is better than that.

    2. Can more than one phones control this relay? for example i want all my siblings can also control my room lights and fan etc from their phone.
    If both features are possible i would suggest to make another video bcoz this kind of video tutorial is not available on youtube.

    This Project has issue. If we use manual control, the status of relays not upated in Alexa. i.e. If on the go I want to switch off relay 3 by switch, the relay will switch off but alexa will show its status as swich ON in Alexa App.. Even in case of manual operation of switch , the status of relay/lamp should be updated in Alexa App.

So by activating the the realys by their discretes buttons , I can not see the relevant status on the Alexa application on my cell phone. Is there any possibility to implement a real status feedback to alexa application please ? Thank for all . regards, Bye

      Please let me know in which project you are facing problems. In this video I have used active low relay module. So to turn on relays I have to give LOW signal in contact pins.
