19 Relay in one place :O

Hi Everybody,

I have to control 19 device in one place (230V). Nothing special, simple on/off and current status. As I know a PI can control only 16 relay. Do you know any device, what can control 19 device, and the openhab can communicate, and control it? :slight_smile:

Thx a Lot

You can use a I/O-expander, e.g. I2C MCP23017
A PI3 hast 26 GPIOs.

Ohh, wait, than its resolve, and I have to go shopping :smiley:

I use pokeys57e for inputs and outputs, each support 55 I/O pins.

Thanks a lot everybody :wink:
