Connect to Cloud

Installing the TankSync™ app, creating an account, and linking your receiver so you can check your tanks from anywhere.

This is optional. The hub, its display, the local web UI, the buzzer and Home Assistant all work with no account and no internet. The cloud adds remote access and push notifications. Skip this page entirely if you only want local monitoring — see HACS Integration instead.

Part 1 — Install the app

TankSync is a Progressive Web App. There's nothing to download from the App Store or Play Store; you install it straight from the browser.

Open:

tanksync.smartghar.org

iPhone / iPad

Must be Safari — other iOS browsers can't install web apps.

1. Tap the Share button
2. Scroll down and select Add to Home Screen
3. Confirm the name, tap Add

Android

Use Chrome.

1. A banner usually appears offering to install the app — tap it
2. If it doesn't appear, open the browser menu and choose Install App (or Add to Home Screen)

Either way it lands on your home screen and opens like any other app, full screen, no browser chrome.

Create your account

1. On the welcome screen, choose Don't have an account?
2. Enter your name, email address and a password
3. Select Create Account
4. A one-time verification code is emailed to you — enter it to activate

Then sign in. The dashboard will be empty until you link a receiver, which is the next part.

Part 2 — Link your receiver

Before starting, make sure your receiver is already connected to your local Wi-Fi (Setup — I Bought a Kit) and you're signed in to the app.

Step 1 — Start Add Hub

If this is your first receiver, the app shows Add Hub automatically.

If you've added one before, tap + in the top-right corner and select Add Hub.

Step 2 — Choose the connection method

Select I already have a Hub on my network — that's the case for any receiver you set up through the local portal.

Step 3 — Open the local dashboard

Here's the bit that catches people: you need a second device.

Switch to another device on the same Wi-Fi — laptop, desktop, tablet, or another phone. Open a browser, go to the IP address shown on the receiver's display, and open the Cloud page.

You'll see a QR code and your receiver's Device ID.

Why a second device? You're scanning the QR code with the phone running the app, so the code needs to be displayed on something else. If you only have one phone, use the manual Device ID method in Step 5 instead.

Step 4 — Scan the QR code

Back in the app, select Scan QR Code and allow camera access. Point it at the QR code on the receiver dashboard. The app detects the receiver automatically.

Step 5 — Or enter the Device ID manually

If you can't scan:

1. Select Enter Device ID Manually
2. Type the Device ID exactly as shown on the receiver dashboard
3. Tap Check Receiver

The app verifies the receiver and prepares it for pairing.

Step 6 — Connect

Once the receiver has been found, select Connect. It securely links itself to your account.

This is a one-time operation. After it's done the receiver stays connected to your account by itself, across reboots, Wi-Fi changes and firmware updates.

Step 7 — Verify

Return to the main dashboard. Within a few seconds your receiver and its tanks appear. If the transmitter has already reported, you'll see the current water level and battery status immediately.

Your system is now reachable from anywhere with an internet connection.

If the receiver isn't detected

• Phone and receiver on the same Wi-Fi? The claim happens over your local network.
• Is the receiver actually online? It needs internet, not just Wi-Fi — check it isn't sitting on a network with no route out.
• Refresh the local dashboard and try scanning again. The QR code is regenerated on load.

Still stuck? Contact support from inside the app — see App Settings.
