Why am I receiving a message that Phyn is not sending data?

Last updated on 30 Jan, 2026

If your water is intentionally turned off, Phyn will send this alert once per day. This is expected behavior for homes where water is shut off.

If your water is not turned off and you receive the alert:

“Your Phyn device at [Home name] is not sending data and is unable to monitor usage or detect leaks at this time”

Phyn is temporarily unable to upload sensor data. When this happens, Phyn cannot monitor water usage, run plumbing checks, or detect leaks until communication is restored.


Step 1: Reboot your Phyn device

  1. Unplug the Phyn device from the electrical outlet.

  2. Wait 30 seconds.

  3. Plug the device back into the outlet.

If the issue persists, continue troubleshooting below.


Common causes and solutions

Mesh Wi-Fi routers

Phyn operates only on the 2.4 GHz Wi-Fi band. Many mesh routers broadcast a single SSID that dynamically switches between 2.4 GHz and 5 GHz, which can interrupt Phyn’s connection.

When this happens, you may see these alerts:

  • “Your Phyn device at [Home name] is not sending data and is unable to monitor usage or detect leaks at this time”

  • “Your Phyn device at [Home name] is back online and working normally”

To resolve this, you may need to:

  • Create a dedicated 2.4 GHz SSID

  • Use a 2.4 GHz guest network

  • Temporarily disable 5 GHz during pairing

Refer to the Mesh Network Help article for detailed steps.


Internet service provider (ISP) limitations

Slow or restricted internet connections can prevent Phyn from uploading data.

This commonly occurs with:

  • DSL connections

  • Satellite internet

  • 4G or SIM-based internet

  • Plans with data caps or throttling

Check with your ISP to confirm:

  • Upload speed is at least 5 Mbps

  • Your plan does not throttle or cap upload speeds

If necessary, upgrade to a higher-tier internet plan.


Check for a DNS or ad-blocking issue

Signs of a DNS issue

  1. Launch the Phyn app.

  2. Tap Menu > Water Use Plus.

  3. Tap different days on the calendar.

If total gallons appear but zero events are shown, data may not be uploading.

Next:

  1. Launch the Phyn app.

  2. Run a Plumbing Check.

If plumbing checks always fail with:

“I wasn’t able to run a plumbing check. Please try again”

This strongly indicates a DNS or ad-blocking issue.


Common DNS-related causes

  • ISP router DNS settings blocking AWS Kinesis traffic

  • Certain Cox and Comcast Xfinity router models

  • Modified router DNS settings

  • pi-hole configured as your DNS server

  • pi-hole blocking in-app or background traffic

  • AWS Kinesis (kinesis.us-east-1.amazonaws.com) blocked

  • Port blocking enabled on the router


How to fix DNS-related issues

Change your router’s DNS settings

You can switch to a public DNS provider such as:

  • Google Public DNS

    • Primary: 8.8.8.8

    • Secondary: 8.8.4.4

  • OpenDNS

    • Primary: 208.67.222.222

    • Secondary: 208.67.220.220

  • Cloudflare

    • Primary: 1.1.1.1

    • Secondary: 1.0.0.1

Additional steps

  • Disable pi-hole as your DNS server

  • Disable port blocking on your router

Once network communication is restored, Phyn will automatically resume uploading data and you should receive a “back online” message.

If issues continue after completing these steps, contact Phyn Customer Support for assistance.
