The CCGX only has one relay however Cerbo GX has two and the Raspberry PI (including Stetson) have 6 defined.
Currently, systemcalc crashes if more than two relays are defined in /etc/venus/gpio_list.
There are four functions to which relay 1 can be attached: Alarm, Generator start/stop, Tank Pump, and Manual. Currently, only the first relay can be assigned to a function. The second relay is only controlled manually from the GUI (or dbus).
I propose adding full support for at least 3 relays so the three assignable functions can be output via relay at the same time. Support for 3 additional relays with only Manual control should also be provided.
