Tesla + Google Home: connect your Tesla to your smart home

Tessie + IFTTT

Generate a Tessie access token, then build an IFTTT applet: Google Assistant "Activate Scene" > Webhooks "Make a web request" to Tessie's command URL (for example start_climate). IFTTT needs a paid plan, and Tessie is paid too.

TeslaFi + IFTTT

TeslaFi documents the same IFTTT pattern with its own API commands, such as charge_start.

Home Assistant

Home Assistant's Tesla Fleet integration plus Google Assistant support can expose car controls to Google Home. Technical, but no IFTTT needed.

1. Preconditioning by voice

1. Google Home app > Settings > Works with Google > IFTTT, then sign in.
2. Tessie app > Settings > Developer > Generate Access Token.
3. ifttt.com/create > If This: Google Assistant > Activate Scene, name it "climate".
4. Then That: Webhooks > Make a web request, GET https://api.tessie.com/VIN/command/start_climate?access_token=TOKEN.
5. Say "Hey Google, activate climate".

2. Start or stop charging by voice

1. Repeat the applet with the start_charging or stop_charging command.
2. Name the scenes "start charging" and "stop charging".

3. Garage on arrival (with limits)

1. Add your garage opener to Google Home (for example Meross).
2. Google asks for a PIN to open and can't take it inside routines, so automatic arrival opening is unreliable.
3. Use the car's HomeLink/Smart Garage (if available), or the opener's own app, for arrival opening.

4. “Hey Google, I’m heading home” routine

1. First, build the IFTTT “climate” applet from routine 1.
2. Google Home app > Automations > + > Household (or Personal).
3. Add starter: When I say to my Google Assistant, and type “I’m heading home”.
4. Add action: Adjust home devices > your thermostat > set heat or cool to a comfortable temperature. Add lights or a porch plug if you like.
5. Add action: Try adding your own, and type “activate climate” so the IFTTT applet warms the car. Custom commands like this can be unreliable, so test it, and say the command on its own if it doesn’t fire.
6. Save, then say “Hey Google, I’m heading home”.
