Sure Petcare hub: stuck in a red-light loop and won't connect
What you're seeing right now
Verify your hub's light status before performing a reset:
- Solid Red Ears: The hub is performing an active software/firmware update. This process can take up to 30 minutes. Power cycling or resetting now can corrupt the memory and permanently brick the hub. Wait for the update to finish.
- Flashing Red Ears: The hub's software has crashed, or it has lost connection to Sure Petcare's servers. A factory reset is safe to perform only when the ears are flashing red.

💡 Quick Resolution Summary (BLUF)
- Solid Red vs. Flashing Red: Solid red ears indicate a firmware update in progress. Flashing red ears indicate a network crash or server link failure. Never unplug or reset the hub while ears are solid red.
- Ethernet Connection Required: The Sure Petcare Connect Hub does not have Wi-Fi capabilities; it connects to your router exclusively via an Ethernet cable. The 10-meter (33-foot) range rule applies only to the RF link between the Hub and pet devices.
- 10-Second Base Reset: A factory reset is performed by holding the physical button on the base of the hub (underneath) for 10 seconds while plugging in the power cable. No pin or paperclip is required.
Sure Petcare Connect Hub status light codes
| LED Status (Ears) | System State | Underlying Meaning | Required Action |
|---|---|---|---|
| Solid Red | Firmware Update | The hub is downloading and writing a software update. | DO NOT UNPLUG. Wait up to 30 minutes for the process to complete. |
| Flashing Red | Connection Failure / Crash | The hub has suffered a boot loop or lost outbound server connection. | Perform the 10-second factory reset using the button on the base. |
| Flashing Green | Pairing Mode | The hub is actively searching for local microchip feeders or pet doors. | Press the pairing button on your pet feeder or door to link it. |
| Solid Green | Connected Standby | The hub is online, connected to cloud servers, and working normally. | None (normal operating state). |
01 — Why the hub gets stuck flashing red
The Sure Petcare Connect Hub serves as a wireless bridge, converting the local Radio Frequency (RF) telemetry of microchip pet feeders and doors into internet-bound cloud updates. When a firmware deployment or security handshake fails, the hub gets stuck in a boot loop.
Cloud-side security migrations
During server-side migrations (such as upgrading SSL/TLS certificate frameworks or changing security handshake tokens on the AWS cloud endpoints), older hub firmware builds can encounter negotiation failures.
Because the hub's internal software is optimized for legacy cryptographic suites, it fails the handshake and crashes on boot. This triggers a rapid flashing red loop on the ears as the hub constantly reboots to retry the connection.
Software write failures (firmware corruption)
When Sure Petcare pushes automated firmware updates over the internet, the hub writes the fresh software blocks to its local EEPROM storage. If the internet connection drops or suffers packet fragmentation mid-write, the firmware file becomes corrupted.
Unlike modern devices that carry dual-boot partitions, the Sure Petcare Connect Hub has no automatic recovery image. It is stuck with corrupt software blocks, resulting in a persistent flashing red state on boot. A factory reset is the only way to purge the corrupted local storage sectors and force the cloud to push a fresh copy.
Follow these step-by-step instructions to perform a factory reset and download a fresh firmware package.
02 — Step-by-Step Fix Checklist
Work through the diagnostic steps in order. Make sure you do not interrupt the power supply once the hub begins download re-initialization.

Official hub bridgingmicrochip feeders, pet doors, and the app. Restores smart feature capabilities.
If the hub continues to loop flashing red after these steps, it likely needs a replacement unit.
03 — Sourcing and replacement options
If the factory reset fails to clear the flashing red loop, the hub's internal flash storage or Ethernet controller board has suffered permanent hardware failure.
If your unit is under warranty, contact Sure Petcare customer support for a replacement unit. If out of warranty, you can source a new Connect Hub on Amazon to restore cloud features to your feeders and pet doors.

Use these configurations if the hub resets successfully but drops offline repeatedly on managed home networks or specific ISPs.
Hub drops offline during peak hours on Comcast/Xfinity routers →
DHCP Lease Renewal Mismatch (General Best Practice): Xfinity all-in-one gateways use short DHCP lease times. When the hub attempts to renew its local IP address, the gateway's security engine may block the renewal request because the hub uses a legacy TCP stack.
Log into your gateway interface (typically 10.0.0.1). Navigate to Connected Devices and locate the Sure Petcare Hub (listed under its MAC address starting with `00:0e:c6`). Assign it a **Static IP Reservation** to bypass the DHCP renewal cycle entirely.
Hub fails to connect through a managed network switch →
IGMP Snooping & Multicast Filtering (General Best Practice): Managed switches use IGMP snooping to reduce multicast traffic. If the switch filters the hub's discovery frames, it will fail to link.
Disable IGMP Snooping on the specific port connected to the hub, or place the hub's port on a separate unmanaged switch connected directly to the primary router.
Frequently Asked Questions
Why is my Sure Petcare hub flashing red?
Rapidly flashing red ears usually indicate that the hub crashed during a software update or lost connection to the cloud servers. A factory reset forces the hub to delete corrupted local files and prompts the servers to push a fresh software update.
How do I factory reset the Sure Petcare Connect Hub?
Disconnect the power cable. Locate the physical reset button on the base of the hub (underneath). Press and hold the button directly (no pin or paperclip needed). While holding, plug the power cable back in, keep holding for 10 seconds, and release when the diagnostic light sequence completes.
What is the difference between solid red and flashing red ears?
Solid red ears mean the hub is performing an active firmware update. Do not reset or unplug the unit during this time, as it can brick the hub. Flashing red ears represent a connection crash or update failure, which is safe to reset.
Will a factory reset delete my pet profiles or microchip settings?
No. All pet microchip numbers, feeding schedules, and lock settings are stored in the Sure Petcare cloud databases, not on the hub itself. Resetting the hub only clears its local pairing key. Once you re-add the hub in the app, your configuration will restore automatically.
