Hi.
Is it possible to expand beyond 16 zones? If so what hardware is required?
Have a great day!
UPDATE:
The new SW release now supports expansion of the GPIO outputs using the MCP23017 chip. Each chip can add 16 ports. As this chip can be set for up to 8 different I2C addresses, the total expansion capacity with 8 chips will be 16x8 = 128
