**If you’re experiencing issues with your Zigbee network on Homey, here are advanced troubleshooting steps to help optimize performance and stability, especially in more complex environments:** 1. **Power Supply Integrity** A stable power supply is critical for Homey’s performance. An underpowered adapter can lead to instability in the Zigbee network. Always ensure you’re using a reliable adapter providing at least 2A. Power fluctuations can cause disconnections or communication failures, especially under high device loads. 2. **Optimal Placement for RF Performance** Zigbee networks are sensitive to radio frequency (RF) interference. Avoid placing Homey too close to high-powered Wi-Fi routers or access points. Both Zigbee and Wi-Fi operate on the 2.4 GHz band, so a physical separation of at least 2 meters is recommended to reduce interference. This improves both range and signal stability. 3. **Wi-Fi Channel Interference Mitigation** Zigbee performance can degrade if it overlaps with congested Wi-Fi channels. Use a Wi-Fi analyzer to identify which channels are being used by surrounding networks, especially if neighboring Wi-Fi networks are contributing to interference that you cannot control. Homey’s Zigbee channel can be changed if conflicting networks are unavoidable. To do this, go to **Homey Settings \> Zigbee** and perform a Zigbee network reset, allowing you to select a less congested channel. Note that changing the channel will require re-pairing devices, so plan accordingly.For more detailed guidance on avoiding interference between Zigbee and Wi-Fi channels, visit this resource: [Zigbee and Wi-Fi Interference: How to Avoid Channel Overlap.](https://www.metageek.com/training/resources/zigbee-wifi-coexistence/) 4. **Ensure Adequate Mesh Backbone (Routers)** Zigbee relies heavily on a mesh network made up of mains-powered devices (routers) to extend and strengthen signal propagation. When you setup a new Homey it’s critical you start with several mains-powered routers, such as smart plugs or bulbs, to ensure stable routing paths as they form the foundation of your network. An excess of early added battery-powered end devices can weaken the network’s integrity, as they don’t relay signals. 5. **Strategic Placement of Routers for Remote Devices** Devices that are located far from Homey or behind dense walls may struggle with weak connections. To ensure proper communication, place powered Zigbee routers between distant devices and Homey to relay signals. Without this, battery-powered devices may experience packet loss or become unreachable over time. 6. **Centralized Network Topology** For optimal network coverage, position Homey as centrally as possible in your home relative to your Zigbee devices. In larger setups or multi-story buildings, place routers in a star pattern to reinforce signal distribution, ensuring that peripheral or isolated devices maintain a strong connection. 7. **Zigbee Chip Memory Limitation** Over time, frequent additions and removals of devices can fill the memory of Homey’s Zigbee chip, which retains information about previously connected nodes. This can lead to running out of free slots, causing instability or preventing new devices from being added. A full Zigbee network reset will clear the chip’s memory and resolve these issues. Before proceeding with a reset, ensure you have a **recent backup**. Homey’s backup feature will allow you to restore all your devices and settings after the reset, so you won’t have to reconfigure everything from scratch. 8. **Full Zigbee Reset and Rebuild** If you’re still facing issues after implementing these fixes, performing a full reset of the Zigbee network may be necessary. This step wipes the network configuration and requires re-pairing all devices. Pair mains-powered devices first to establish a solid mesh network before adding battery-powered devices. A **backup** is crucial before this process, as restoring from it will save time and effort by re-adding all your devices seamlessly post-reset. 9. **Congestion from Overactive or Faulty Devices** Network congestion can occur if certain devices are configured to send too many reports, or if a device is malfunctioning and flooding the network with unnecessary data. This can cause delays and affect overall network performance. To identify these problematic devices, monitor traffic patterns using Zigbee sniffer tools or Homey’s developer tools to inspect the frequency and volume of data being transmitted by each device. If a device is over-reporting (e.g., sending updates every second), adjust its reporting interval settings, or if faulty, consider removing it from the network temporarily to assess its impact. Implementing a robust mesh infrastructure, managing memory limitations, and identifying devices causing congestion will help maintain high performance and stability across your network. --- _[View the full topic](https://community.homey.app/t/advanced-zigbee-troubleshooting-on-homey/115930)._
