Help! Need automation to turn on smart plug when nest (ac turns on)

[SmittyKen12]

 

I need to automate a kasa smart plug (hvac in line fan plugged into that) turning on somehow when The nest (air conditioning) turns and when  the nest (fan only on ac) turns on  

How can I accomplish this?   Google automate?  

Or IFTTT?  

I did see IFTTT had an applet with nest fan/wemo plug but not for mine…here it is https://ift.tt/wf8Ng4H 

But it tells me there’s gotta be a script or coder some way to do it. I just need it in simple language

plz and thanks

Example:

metadata:

  name: Cool weather heating

  description: If it is cool, open blinds, turn on fans, and adjust thermostats.

automations:

- starters:

  - type: device.state.TemperatureSetting

    state: thermostatTemperatureAmbient

    device: thermostat - Family Room

    lessThan: 18C

  actions:

  - type: device.command.OpenClose

    devices:

    - blinds - Bedroom

    openPercent: 100

  - type: device.command.OnOff

    devices: fan - Bedroom

    on: true

  - type: device.command.ThermostatTemperatureSetpoint

    devices:

    - thermostat - Family Room

    thermostatTemperatureSetpoint: 21C

That doesn’t help respectfully- 

I only want the smart plug to turn on when the nest turns on the air conditioner

Do you use the Google Home App or the Google Home web page?

[SmittyKen12]

I could use either

[Pitsom]

OK. I use the Google Home App on my Smartphone to see my Home and all the Devices. There you can Edit simple automations too. If you wont writing scripts you have to go to the Google Home web page.

 I have the same question - want to power on a whole home scent diffuser connected to my hvac but only when hvac (via Nest thermostat) is on

[Tressielman]

I’m trying to do the same thing.  Did you ever figure this out?

Google Home allows it but only through Script Coder in the desktop version. Phone app will not allow it. I wanted to turn on and off my HVAC scent diffuser when the HVAC was running / not running and achieved it using the following code. This is the code for turning the outlet ON:

metadata:
  name: Turn on Diffuser when the temperature rises above 77.9.
  description: Turn on Diffuser when the temperature rises above 77.9.
automations:
  - starters:
      - type: device.state.TemperatureSetting
        device: Downstairs - Downstairs
        state: thermostatTemperatureAmbient
        greaterThan: 77.9F
    actions:
      - type: device.command.OnOff
        devices:
          - Smart Plug Scent Diffuser - AC Cabinet
        on: true

[Tressielman]

Thank you so much.  I just saw this and found the script coder.  You said this is to turn on? Is there a separate to turn the plug off when the thermostat turns off?  I'm sorry, I'm clueless on this and trying to muddle my way through.  Thanks again.

No issues. We have all been there:)

To Turn On the AC Booster use this code:

metadata:
  name: Turn on AC booster when the thermostat fan is on
  description: When the thermostat fan is on then turn on the AC booster
automations:
  - starters:
      - type: device.state.OnOff
        device: Upstairs - Upstairs
        state: activeThermostatMode
is: cool
    actions:
      - type: device.command.OnOff
        devices:
          - AC booster supply - Master Bedroom
        on: true

To Turn OFF the AC Booster use this code: 

metadata:
  name: Turn off AC booster when the thermostat fan is off
  description: When the thermostat fan is off then turn off the AC booster
automations:
  - starters:
      - type: device.state.OnOff
        device: Upstairs - Upstairs
        state: activeThermostatMode
isNot: cool
    actions:
      - type: device.command.OnOff
        devices:
          - AC booster supply - Master Bedroom
        on: false

[Tressielman]

Thank you.  You are so helpful.  I was asking about code for turning on/off a smart plug (with diffuser) when HVAC turns on/off, not the booster. 🙂

[maxthekojo]

Replace the Booster word with plug lol

Make sure your device names are accurate in the code below. Replace AC Booster with whatever you call the plug

To Turn On the plug use this code:

metadata:
  name: Turn on plug when the thermostat fan is on
  description: When the thermostat fan is on then turn on the plug
automations:
  - starters:
      - type: device.state.OnOff
        device: Upstairs - Upstairs
        state: activeThermostatMode
is: cool
    actions:
      - type: device.command.OnOff
        devices:
          - AC booster supply - Master Bedroom
        on: true

To Turn OFF the plug use this code: 

metadata:
  name: Turn off plug when the thermostat fan is off
  description: When the thermostat fan is off then turn off the plug
automations:
  - starters:
      - type: device.state.OnOff
        device: Upstairs - Upstairs
        state: activeThermostatMode
isNot: cool
    actions:
      - type: device.command.OnOff
        devices:
          - AC booster supply - Master Bedroom
        on: false

[Tressielman]

OK!! I kinda thought that would be the answer but wanted to ask.  Planning to try to get this working when I get home, so I'm trying to combat future frustrations. 🙂  Thanks again. 

[maxthekojo]

Good luck - it should work. Mine's working perfectly

Hello everyone, 

If anyone can help, I would really appreciate it.

I am trying to do the same thing but trying to use the state of the fan from my heat pump controlled by my nest thermostat to activate a booster fan.

   Gemini assistant is trying to have me use the state fanOn, but that isn't a valid state for type device.state.OnOff

   The name of the thermostat is upstairs and that seems to be correct 

Below is the script and I've bolded the error

metadata:
  name: Turn on AC booster when the thermostat fan is on
  description: When the thermostat fan is on then turn on the AC booster
automations:
  - starters:
      - type: device.state.OnOff
        device: Upstairs - Upstairs
        state: fanOn
        is: true
    actions:
      - type: device.command.OnOff
        devices:
          - AC booster supply - Master Bedroom
        on: true

[maxthekojo]

Try this:

metadata:
  name: Turn on AC booster when the thermostat fan is on
  description: When the thermostat fan is on then turn on the AC booster
automations:
  - starters:
      - type: device.state.OnOff
        device: Upstairs - Upstairs
        state: activeThermostatMode
is: cool
    actions:
      - type: device.command.OnOff
        devices:
          - AC booster supply - Master Bedroom
        on: true

[maxthekojo]

Found an error in code I sent. The correct code is:

metadata:
  name: Turn on AC booster when the thermostat fan is on
  description: When the thermostat fan is on then turn on the AC booster
automations:
  - starters:
      - type: device.state.OnOff
        device: Upstairs - Upstairs
        state: activeThermostatMode
isNot: cool
    actions:
      - type: device.command.OnOff
        devices:
          - AC booster supply - Master Bedroom
        on: false

Thank you,  

  THat has worked to turn it on - but now I can't get it to turn off when the HVAC system turns off.

  I tried  

   state: ActiveThermostatMode

  is: heatcool     

and it didn't turn off.

I always have the same temps set all day, would it be better to set the parameters by temperature?

[maxthekojo]

To turn off, replace "is: heatcool" with "isNot: cool"

[maxthekojo]

I find temperature based activation / deactivation laggy so stick to this. This works perfectly
