Salinity module

[martinresi]

If I get the salinity expansion module would I need to purchase an expansion hub first?

All i have so far is the RA Plus controller and wifi module. i.e. does the wifi module count as the 1 expansion?

Thanks,
Todd

No need for the hub just yet! The wifi doesnt count!

You can hook up 1 expansion module before you need to buy the expansion hub.
