If you wanted to hook it up to your lap top , you can purchase the SID v2 cable for $25 . It would plug into the bus cable that the temp probe is plugged into . You can set up the timers, you can have the outlet where your heater is plugged into turn off if tank temp reaches X number of degrees incase the heater fails in the "on "position . You can program what plugs you want to be in standby mode when feeding or doing maintenance. There is still a lot of things you can program even with just the one power strip . After you make all your settings you unplug the SID and plug back in the temp probe. Plus if there are any firmware updates to the unit you can update the same way. It would be a good idea to have that cable anyway.
