No problem :)

OHS is stand alone system for sure.

I'm not sure about Hubitat or Smartthings, I do not know them. OHS gateway can communicate via MQTT as for now, but it is open source, you can add any desired protocol. Only thing what is not possible is SSL/TLS.

I2C was my option on beginning as well, but personally use only 7 balanced and 2 digital zones, and no one shown to much interest into expansion board. 8 channel ADC connected via I2C was my plan. Consumption is not critical as PIRs will consume more then expansion board anyway.
Current solution is more flexible, it allows you to add expansion board far far away then over I2C and even trough wireless.

MQTT is not really required, but gateway uses MQTT to check Ethernet connection. If not found gateway periodically reset Ethernet driver.
