Two inputs one output ?

  • Quick question about the Plus 2 PM...
    Can the two inputs be configured to control one output?
    This would leave the second output unconnected, or can the outputs be linked together without problem?

    The situation two switched outputs from single port heating valves to then call for demand from a boiler. Currently they are just paralleled into one feed out. I would like to monitor which valve is actuated.
    This could be achieved with relays, but the shelly units are so much neater...

    Thanks

  • There’s more than one way to skin a cat!

    (a) It is possible to connect the two SW pins in parallel to a single contact,

    (b) By the means of an action, it is possible to switch both outputs from one input.

  • I have a similar application and just want to confirm what I think this says … can the Shelly Plus 2 do this:

    Turn Output O1 = ON

    when SW1 or SW2 = ON

    And when SW1 and SW2 = ON

    Turns O1 = OFF

    when SW1 and SW2 = OFF.

    Bonus question :)

    Can you create separate actions and schedules for SW1 and SW2?

    For example: SW1 ON only activates O1 at specific times and SW2 ON only activates when commanded by voice/button/motion.

    Thanks
