Sure petcare hubs clashing: slow door reactions and offline flaps
- Ethernet Link Mandatory — The Sure Petcare Connect Hub has no Wi-Fi capabilities; it connects to your router exclusively via a physical Ethernet cable. When relocating hubs, they must remain plugged into your network router or a connected switch.
- 10-Meter RF Range Limit — The wireless link between the Hub and pet devices (feeders, pet doors) uses low-power RF with a maximum range of 10 meters (33 feet), with a clear line of sight recommended. There is no official minimum distance required between hubs themselves.
- Staggered Booting Resolves Channel Clashes — Simultaneous power-ups (e.g., after a power outage) cause hubs to pick overlapping radio channels. Powering them on one by one with a 5-minute delay allows the second hub to scan and select a non-conflicting channel.
- Distance-Induced Battery Drain — Cat flaps do not adjust their transmission power dynamically. Instead, placing a flap too far from its paired hub causes packet drops and frequent retransmissions, which is what drains the batteries. Re-pairing devices to the physically closest hub resolves this.
This guide is specifically designed for households running two or more Sure Petcare Connect Hubs to expand coverage. If you only have one hub and are experiencing offline issues, please check for standard signal obstructions or consult our hub reset guide TB-SPC-002.
Your pet may be shut in or shut out right now. Prop the flap open or use another door until this is fixed — that matters most in hot or freezing weather.
Why two hubs clash and cause delayed responses
The Sure Petcare Connect Hub serves as a wireless bridge between your smart pet flaps or feeders and the internet. When you run multiple hubs to cover a large house, radio channel collisions and improper placement can degrade performance.
Simultaneous boot channel overlap
During startup, each hub scans the local 2.4 GHz spectrum (802.15.4 protocol) to select a quiet channel. If both hubs boot simultaneously (such as after a power cut or when plugged into the same power strip), they cannot detect each other's signal selection in time. As a result, they lock onto overlapping channels. This causes wireless data packets to collide, resulting in slow app updates, delayed flap openings, and missed pet entry records.
Receiver saturation from electronics
The hub's internal radio works on the 2.4 GHz band. Placing a hub directly adjacent to a Wi-Fi router, mesh access point, or large metal surface can saturate its sensitive receiver. While Sure Petcare does not prescribe a specific minimum distance, keeping the hub clear of metal surfaces, thick walls, and other active electronic transmitters prevents signal interference and keeps your pet devices online.
Step-by-step fix checklist
Follow these steps to eliminate radio conflicts and ensure each flap communicates with its optimal hub.

If the fix doesn't work
If a specific flap remains slow or offline after re-pairing to its closest hub, the hub covering that area may have a damaged radio, or you may need an additional hub for very large or heavily walled properties to bridge the distance.

Advanced placement and channel management
These advanced configurations apply to networks with commercial access points or complex architectural setups.
| RF Parameter | Specification | Description & Multi-Hub Optimization |
|---|---|---|
| Radio Protocol | 802.15.4 Low-Power RF (2.4 GHz) | Proprietary wireless link connecting hubs to pet doors and feeders. Separate from standard home Wi-Fi. |
| Channel Selection | Dynamic Channel Scan on Boot | Hubs scan the spectrum on boot. Powering them on with a 5-minute delay prevents channel collisions. |
| Operating Range | Maximum 10 meters (33 feet) | Recommended distance between a hub and its paired pet door. Obstacles (metal/walls) reduce range. |
| Transmit Power | Fixed 5 dBm (Low-power) | Pet doors do not adjust signal power. Distant hubs force retransmissions, leading to rapid battery drain. |
| Outbound Ports | TCP Port 443 (HTTPS) | Outbound server links are HTTPS-only. Requires open port 443 on firewall profiles. |
Still getting interference despite good placement
If your router's 2.4 GHz channel is set to "Auto", the router periodically switches channels to avoid local congestion. Every time it switches, the hubs lose their quiet frequency space and may fall back into an overlapping channel. Locking the router's 2.4 GHz channel removes this variable.
Fix: In your router's wireless settings, find the 2.4 GHz channel configuration and change it from "Auto" to a fixed channel—use 1, 6, or 11 only (these are the three non-overlapping options in the 2.4 GHz spectrum). After locking the Wi-Fi channel, restart both hubs using the staggered process in steps 2–4 above so they can re-select their own clean channels in the newly stable environment.
App connectivity and cloud server paths
The Sure Petcare app communicates with your hubs exclusively via AWS cloud servers. The app does not perform local network broadcast discovery (like mDNS, Avahi, or UPnP). If you have isolated your hubs on a separate IoT VLAN, you do not need to configure mDNS repeaters or Avahi bridging.
Fix: Simply ensure that the IoT VLAN has unrestricted outbound HTTPS (port 443) access to the internet so the hubs can maintain their connections to the Sure Petcare API endpoints.
Understanding the 10-meter RF signal range limit
The wireless link between the Sure Petcare Hub and your pet doors or feeders uses the 802.15.4 protocol on the 2.4 GHz band. The official maximum operating range is 10 meters (33 feet). Sure Petcare recommends a clear line of sight where possible.
Rule of thumb: Structural obstacles like metal doors, reinforced concrete, or thick brick walls will significantly reduce this range, sometimes down to 3–5 meters. If your pet door is too far from the hub, you must add an additional hub closer to the door, keeping them on separate channels using our staggered power-on procedure.
Frequently asked questions
Yes. Large homes or structures with dense walls can utilize multiple hubs to extend coverage. However, they must be powered on sequentially (staggered by 5 minutes) to ensure they select different, non-overlapping radio channels, and pet doors should be paired to their physically closest hub.
What is the maximum wireless range of a sure petcare hub?
The official maximum wireless range for the low-power RF link between a Sure Petcare Hub and its connected feeders or pet doors is 10 meters (33 feet). A clear line of sight is highly recommended, as metal surfaces, thick masonry, and active electronic transmitters can significantly degrade this range.
Why does my sure petcare cat flap respond slowly or go offline?
Slow response times or offline states are typically caused by radio frequency channel conflicts between multiple hubs, or by placing a hub near metal surfaces and other active transmitters. Powering the hubs on one by one resolves channel conflicts, while placing the hubs within 10 meters of their respective flaps ensures a strong signal.

Still not fixed? Here’s what to do next.
Some faults are genuinely hardware, and no amount of cleaning or resetting will clear them. If you’ve worked through everything above and it’s still doing it, stop here rather than taking the unit further apart.
- Go to Sure Petcare directly. If the unit is still under warranty, let them replace the part rather than paying for it yourself — contact Sure Petcare support.
- Tell us what didn’t work. We rewrite bulletins when readers show us a case they don’t cover — compliance@pet-infrastructure.com. Tell us the model, what the lights are doing, and which steps you already tried.
- Ask other owners. Search Reddit for your model name plus the symptom (for example “Sure Petcare Connect Hub not cycling”). Someone has almost certainly hit the same fault, and owner threads often surface fixes before the manufacturer documents them.
When to stop and call the manufacturer: if the fix needs the base opened, the motor or control board touched, or any tool beyond a screwdriver — stop. On a unit in this price range, opening it yourself usually voids the warranty, and a warranty repair costs nothing.
