Sure Petcare hubs clashing: slow door reactions and offline flaps
Multi-hub environments only
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.

💡 Quick Resolution Summary (BLUF)
- 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.
Sure Petcare Connect Hub RF parameters
| 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. |
01 — 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.
Follow these step-by-step instructions to eliminate radio conflicts and ensure each flap communicates with its optimal hub.
02 — Step-by-step fix checklist
These six steps force each hub to pick its own clear channel and ensure each flap is paired to the hub closest to it.
Sure Petcare Connect Hub
Get a replacement Connect Hub to expand coverage or replace a unit with a failing radio.
If a flap remains offline after re-pairing to its closest hub, the flap itself may have a damaged radio — contact Sure Petcare support or see the replacement options below.
03 — Sourcing and replacement options
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.
Sure Petcare Connect Hub
A replacement hub covers a new zone of your home without interference. The full connect system bundle is the best value if you're also replacing a flap or door at the same time.

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 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 setting and change it from "Auto" to a fixed channel — use 1, 6, or 11 only (these are the three non-overlapping options). 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 keeps switching between hubs or shows "Searching for Hub" →
The Sure Petcare app discovers hubs on your local network using a broadcast signal. If your phone and the hubs are on separate network segments — for example, your phone is on a "main" network and the hubs are on an isolated "IoT" network — the app's discovery signal can't cross between them. This causes the "Searching for Hub" spinner or the app randomly switching which hub it's looking at.
Fix: In your router or firewall settings, enable "mDNS repeater" or "Avahi" and configure it to relay local discovery traffic between your main network and your IoT network. This allows the app to find both hubs from any device without compromising the security separation between your IoT and personal devices.
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
Can you run two Sure Petcare hubs in the same house?
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.
