What smart home devices and apps are supported through Zapier NLA?

Zapier NLA provides access to 5000+ app integrations including Philips Hue, LIFX, Nanoleaf (lighting), Nest, Ecobee, Honeywell (climate), Ring, Arlo, SimpliSafe (security), SmartThings, Home Assistant, IFTTT, and many more. Use `search_zapier_actions` to discover specific actions for your devices.

How do I get a Zapier NLA API key?

Visit https://nla.zapier.com/ and sign in with your Zapier account. Navigate to the NLA API settings page and generate a new API key (starts with `sk-nla-`). You'll need a Zapier account with exposed actions configured for the smart home apps you want to control.

What is the difference between exposed actions and AI zaps?

**Exposed actions** are individual smart home actions you've configured and made available for AI execution (e.g., "turn on kitchen light"). **AI zaps** are multi-step automation workflows that can be triggered with natural language instructions. Exposed actions are for direct device control, while AI zaps are for complex workflows involving multiple steps and apps.

Can I control devices with natural language commands?

Yes! Use the `send_natural_language_command` tool to send any smart home command in plain English. For example: "turn off all the lights", "set the thermostat to 72 degrees", or "lock the front door". The API will search for matching actions and execute the best match. You can also use `search_zapier_actions` to find specific action IDs for more precise control.
