    Your question is unclear. What kind of switches? What have you done? What is not working? – Fabian Feb 16 '18 at 17:06
  • Sir everything is fine but in a single raspberry pi we can only connect 16 relay(GPIO) i need 80 + – JEGAN nath Feb 17 '18 at 18:19

From your question I can try to deduce the following:

  • You have a large home with ~80 smart switches/lights/things, etc.
  • Based on the fact that you put your question in this forum, you want to control them using a Raspberry Pi.
  • You know about how smart items work, but don't know how to control all of them from a Pi, or where to begin.

For someone in your situation, I would highly recommend looking into an open-source solution called Home Assistant. This open-source app runs on a Pi, and can coordinate the control of a large number of IoT devices from many vendors. Once you get it running and understand the basics, you can then dive deeper and learn to extend it with custom capabilities.

I hope this helps! Good luck in whatever you do.

(PS: I am in no way affiliated with the team/community of people that make the Home Assistant app. I'm just a user of it, and based on your question I think it might fit your needs.)

  • Yes friend But i need more than 16 GPIO ports na ? – JEGAN nath Feb 17 '18 at 18:23
  • So you're saying you want to directly electrically control 80+ relays? If that's the case, you will need a dedicated addressable multiplexer to allow you control so many. I recommend looking into the MCP23017 I/O expander chip. It uses the I2C bus to control up to 16 items, and because you can have up to 8 of them on the bus, you can control up to 128 items from a single Raspberry Pi. I hope this helps! here's a link for info: adafruit.com/product/732 – MrChips Feb 17 '18 at 22:02
