Hi everyone I’m a total beginner in Homey app development, and I ran into a silly issue I just can’t figure out. I created a custom pairing view with a simple form to enter IP and Port for a WiFi bulb. But for some reason, the **Save button doesn’t seem to work** , or maybe `Homey.alert()` is silently failing — I can’t tell what’s going wrong. I followed the official documentation here: [Custom Pairing Views — Homey Developer Docs](https://apps.developer.homey.app/advanced/custom-views/custom-pairing-views) I might be misunderstanding something fundamental, and even ChatGPT couldn’t give me a working fix. Here’s my `enter-credentials.html`: ```html Enter WiFi Bulb Info

Enter WiFi Bulb Information

Please enter the IP and Port of your device

Bulb IP

Port

``` And here’s my `driver.js`: ```js 'use strict'; const Homey = require('homey'); module.exports = class MyDriver extends Homey.Driver { async onInit() { this.log('v2 has been initialized'); } async onPair(session) { this.log('Pairing started'); session.setHandler('save', async function ({ bulb_ip, bulb_port }) { this.log(`Received IP: ${bulb_ip}, Port: ${bulb_port}`); const ipRegex = /^(25[0-5]|2[0-4]\d|1\d{2}|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d{2}|[1-9]?\d)){3}$/; if (!bulb_ip || !ipRegex.test(bulb_ip)) { await session.emit('validationResult', 'Invalid IP address (e.g. 192.168.1.100)'); throw new Error('Invalid IPv4 address'); } if (isNaN(bulb_port) || bulb_port < 1 || bulb_port > 65535) { await session.emit('validationResult', 'Invalid Port (must be 1-65535)'); throw new Error('Invalid port number'); } await session.emit('validationResult', 'IP and Port verified successfully!'); await session.done(); return { success: true }; }.bind(this)); session.setHandler('showView', async function (viewId) { this.log('Switched to view:', viewId); if (viewId === 'enter-credentials') { await session.emit('welcomeMessage', 'Please enter your WiFi Bulb\'s IP and Port'); } }.bind(this)); await session.showView('enter-credentials'); } async onPairListDevices() { return []; } }; ``` Any idea why Homey.alert() might not be showing anything, or why the Save button seems unresponsive? I’m probably missing something obvious. Thanks in advance! ---

Your script starts with `Homey.alert("fronted loading")`, are you saying that that doesn’t work already? If it does, then the conclusion is that `Homey.alert()` works as expected and there’s something else wrong. Run the pairing session from a regular browser ([here](https://tools.developer.homey.app/tools/pair)) while you have your browser’s developer tools/JS console open, and see if any errors occur. You can also add logging steps (using plain `console.log()`) everywhere to see which code is still reached, and where it stops. Your issue will be somewhere in between. ---

Thanks a lot for pointing out browser debugging! I honestly thought pairing could only be tested through the mobile app, and I had no idea the web version could expose logs like that. Once I opened the pairing session in a regular browser and checked the console, I got way more visibility — tons of logs I couldn’t see before. That helped me pinpoint the issue quickly. Appreciate the tip!
