Before MeloDeal can play a jingle on it, your speaker needs to be set up in the Sonos app and linked to a Sonos account. Here's how.
Download the Sonos app (iOS, Android, Mac, or PC) and open it. If your speaker is brand new, plug it into power now. The light on top will pulse white once it's ready to be added. Battery speakers (Move, Roam) just need a single tap of the power button.
Sign in with the Sonos account this speaker should belong to, or tap Create account if the sales floor doesn't have one yet. Use a shared team inbox rather than a personal one. You'll want whoever manages the office AV to have access later, not just the person who unboxed the speaker.
The app detects new speakers on the network automatically and prompts you to add them, or go to Settings → System → Add Product to start manually. Follow the on-screen steps to join it to your Wi-Fi network. This can take a minute; the light will pulse while it connects.
Give it a name that describes where it physically sits, like "Sales Floor" or "Bullpen", rather than the model name. This is the name you'll pick from later when connecting it in MeloDeal, so make it one the whole team will recognize.
The app plays a short chime once setup finishes. That's your confirmation it's online. From here, head to the MeloDeal setup guide and select this speaker from your Sonos account to start playing jingles on it.
