Continuing the discussion from Simple project needs extra unit due to v6 issue:
I’d like to be able to use 2 V6 or later 2-relay units to do the following:
button A - open a (bus) door
button B - close that door
button C - turn on a timed run of “on” for the ignition, second press cancels an unexpired timer
button D - run the starter / crank the engine to start it
Sadly, the current V6 can’t do this - instead there has to be an additional “third” unit used to actually handle the timed “C” - ignition on function.
Solution requirements: Minimum 3 monentary relays, Minimum 1 timed relay.
Details of requirements: 2 momentary for door-open / door-close; 1 timed for “ignition-on”; 1 momentary for “crank/start”
With V6 as it stands: 3 units: Unit X, Unit Y, and Unit Z required.
Unit X Relay 1 Momentary Button A + Relay 2 Momentary Button B - door open with A, close with B
Unit Y Relay 1 Latching Button C + Relay 2 Momentary Button D - ignition-on with C, start with D
Unit Z Relay 1 Timed Button C + (and Buttons A, B, and D to avoid cancelling “ignition on” with “door”
or with “start”
With V6 as it could be fixed: 2 units: Unit X, Unit Y:
Unit X same as above
Unit Y Relay 1 timed Button C + Relay 2 Momentary Button D - ignition-on with C, start with D
No funky programming required, button C shuts off a running car that has been remote started but timer has not expired. Buttons A/B/D have no interaction with C - this is as things should be…
