  • Pro 4PM script - if one switch is on, the other must be off

    Hello @De kat

    I'll like to integrate my shelly into Home Assistant and control from there

    My aim is to turn on the VMC when humidity is above a given value and increase speed when humidity rise up well above that value.

    I'm just beginning with home automation and I'm not a coder, so please be patient.

    I'll try your code today.

    In the meantime I found I can control my shelly with DD Urls and Home assistant has rest commands.

    But I prefere to create a script directly on the shelly so the same behavior is both on Home Assistant and Shelly App if needed.

    Thanks!

    P.S. I just tried it and doesn't work.

    If I use shelly app and click on the two swithes they behave as if no flip is applied. They just turn on/off independently

  • Make time limit in Cover function optional

    Hello

    I just bought a Shelly 2 PM with the purpose to control a fan speed that has two levels.

    The cover function of the 2PM seemed promising to me because of the "OR" logic of the two switches...

    But then I found that the movement in each direction has a time limit of 300 seconds.

    My fan must be on for ours..

    I found a solution here

    RE: Pro 4PM script - if one switch is on, the other must be off

    this is a quick'n dirty solution, but as said: there's probably a few milliseconds delay.

    Explaination:

    if switch:0 is turned on switch:1 (id: 1) is turned off

    if switch:1 is turned on switch:0 (id 0) is turned off

    It's still possible to turn off both relays

    If you prefer to use the remaining switch 3/4 from the Pro4PM just replace the switch:x and "id": y

    but the switching between swithces has little lag so two switches are on for a brief time, I fear this could blow my VMC..

    Is there any hope in some next firmware upgrades to set time limit optional for cover function?

    Thanks

  • Pro 4PM script - if one switch is on, the other must be off

    Hello everybody

    I just purchased a Shelly 2 PM and I upgraded the firmware to the latest stable.

    I want to control a fan (VMC - controlled mechanical ventilation) that has 2 speed.

    The above script from Seven of Nine works fine except for a tiny delay when "switching between switches" so for a bit of time both are on.

    Is there some way to add a little stop to allow the switch that is on to be completely off?

    I bought this shelly hoping that the cover funcion will do it, but cover movement have a time limit max set to 300 seconds..

    I did't find a way to avoid this limit except this code you wrote.

    Thanks!
