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?
Thx a Lot O.
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
I use pokeys57e for inputs and outputs, each support 55 I/O pins.
Thanks a lot everybody
