Important Link:
Cadio Download Center: https://egycad.com/cadio/downloads/

PCB Gerber file: https://drive.google.com/uc?export=do...

Important points:
1. Download the latest firmware from the Cadio Download Center.
2. In Free Plan, you have reupload the firmware after every 500hr
3. Reset the ESP8266 and wait for 30 sec to go to Config mode.
4. To change the WiFi details, Go to config mode, then enter the WiFi credentials from Cadio app.
5. The Boot will fail if the D3 (GPIO-0) (switch-2) pin are connected with the ground during booting.
6. If you use Switch (latched), make sure the switch-1 & switch-2 should be OFF during the ESP8266 Boot.
7. You don't need any Echo devices.
8. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltage.

During the Cadio tutorial video, I explained all the steps to make IoT based home automation system using ESP8266 NodeMCU and Cadio. This is the most easiest IoT platform for beginner, as it required no coding skill. You can do all the configuration from Cadio mobile app.
You can also add timer or create schedule in Cadio app to control the relays automatically. The NodeMCU can also remember the previous states of the relays.

If the NodeMCU is connected with Wi-Fi, then you can control the relays from anywhere in the world with Cadio Alexa and Google Assistant. And you can also monitor the real-time feedback on the Cadio, Amazon Alexa, and Google Home IoT applications. So with this smart home project, you can convert any appliance to IoT devices and control them through the internet.

So, now you can just ask Alexa or Google Assistant, "Hey Google, turn on lights" that's it.
