The process begins with accessing the Shelly 1’s built-in web server. Once connected to your WiFi network, the device is assigned an IP address. You can find this via your router’s admin panel or using network scanning tools like Advanced IP Scanner. With the IP address in hand, open Postman and create a new request. Set the method to GET and enter the URL:http://[device-ip]/relay/0`.This request retrieves the current state of the first relay (on or off. To turn the relay on, change the method to POST and use the same URL with a JSON body: on: true To turn it off, use on: false Postman will send the request and return a response confirming the action. To scale this automation, create a collection in Postman. Name it “Shelly 1 Automation” and add multiple requests: one to check status, one to toggle the relay, and another to retrieve device information (e.g,http://[device-ip]/status`).Use environment variables to store the device IP, so you can easily switch between multiple Shelly 1 units. For example, define an environment variable shelly_ip and reference it as {shelly_ipin your URLs. Next, add pre-request scripts to automate logic. For instance, you can write a script that checks the current time and only allows the relay to turn on during specific hours. Use JavaScript in Postman’s pre-request script section to access thepmobject and manipulate variables. You can also use test scripts to validate responsesensuring the device returned a success code (200) and the expected state. For advanced workflows, integrate Postman with external services. Use the “Newman” command-line tool to run your collection automatically at scheduled intervals. Set up a cron job on a Raspberry Pi or a cloud server to executenewman run shelly-automation.postman_collection.json every 10 minutes. This enables continuous monitoring of your garage door or outdoor lights. You can also combine the Shelly 1 with other APIs. For example, create a workflow where a weather API returns “rain” as a condition, and Postman triggers the Shelly 1 to close your smart curtains. Use Postman’s “Tests” tab to parse JSON responses from the weather API and conditionally execute the relay control request. Finally, visualize your automation with dashboards. Use tools like Grafana or custom web apps to display real-time device status pulled from Postman’s API logs. This transforms your smart home from a collection of devices into a responsive, intelligent system. <h2> What Are the Benefits of Using Postman Over Other Tools for API Automation in Smart Home Projects? </h2> When comparing Postman to other tools for API automation in smart home projects, several distinct advantages make it the preferred choice for developers and hobbyists alike.
