Important Link:
Cadio Download Center: egycad.com/cadio/downloads/
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 and press the BOOT button for 3 seconds to go to Config mode.
4. To change the WiFi details, Go to config mode, then enter the WiFi credentials from Cadio app.
5. You can also connect 8-channel relay module with ESP32.
6. 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 ESP32 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 schedule in Cadio app to control the relays automatically. The ESP32 can also remember the previous states of the relays.
If the ESP32 is connected with Wi-Fi, then you can control the relays from anywhere in the world with Cadio and Google Assistant. And you can also monitor the real-time feedback and sensor reading in the Cadio and Google Home IoT applications. So with this smart house project, you can convert any appliance to IoT devices and control them through the internet.
So, now you can just ask Google Assistant, "Hey Google, turn on lights" that's it.

Unit license cost 800 INR If you are planning to use multiple boards, You need to purchase multiple unit licenses. Rainmaker is cheap & best

[@ravirajkala]

Rainmaker has a major limitation because of which I had to turn to other platforms like tasmota: the esp32 goes offline after wifi outage and has to be power cycled.
