Almost all AC powered devices will serve as a router. You might choose a dedicated router (for example, a SONOFF ZBDongle-E based router open in new window) or a mains-powered Zigbee device (for example, a Hue lamp open in new window) to stabilize your network. Introducing a router ( read more about this) can improve the forward path as well as the return path: However, this simple measure might yield to a network with weird behavior, if messages to an end device reach their target, but responses (or messages) from that end device do not reliably reach the coordinator: Zigbee2MQTT enables the user to increase the transmission power open in new window for some coordinator models. Yet, low transmission power can be the cause of an unstable or unreliable network: "Zigbee is a low-power wireless mesh network standard targeted at battery-powered devices" (see Wikipedia open in new window).
#2.4ghz remote mapper Bluetooth#
# Interference from other 2.4 GHz devicesĪny device using the open 2.4 GHz spectrum could interfere with Zigbee such as Bluetooth or gaming devices like Logitech “Unifying” or “Lightspeed” or Razer “Hyperspeed Wireless”. To change the Zigbee channel Zigbee2MQTT uses you have to set the channel in configuration.yaml. A good article explaining this is Zigbee and Wi-Fi Coexistence open in new window. By using the correct Zigbee channel, interference with Wi-Fi can (partly) be avoided. # Reduce Wi-Fi interference by changing the Zigbee channelĬhanging the Zigbee channel requires repairing of all your devices!Īs Wi-Fi and Zigbee both operate on the same frequency space (2.4 GHz), they can interfere with each other. You might find it useful to buy a small rotating USB connector like this: Try to experiment with positioning and orienting the adapter in space while monitoring the linkquality values reported. You might be having very poor linkquality reports and intermittent ping failures but once the adapter is rotated a little it all can change greatly without re-locating the coordinator far away. RF connection between the adapter and other devices also depends on the way it is oriented in space. # Try different orientations of the adapter
Preferably get one with shielding as this may give better results ( source open in new window).ĭo not underestimate this! Placing your adapter close to an USB port can kill the radio signal entirely as demonstrated in this article open in new window.Īditionally, it may help to plug the adapter to a USB 2 instead of USB 3 port. a Wi-Fi router) or an SSD.Ī USB extension cable of 50 cm is already enough to reduce the interference. Also be sure not to position the adapter too close to any other radio transmitting devices (e.g. When plugged directly into the computer, the antenna suffers from interference of radio signals and electrical components of the computer. The range of these adapters can greatly be improved when connecting them with an USB extension cable instead of directly plugging it into the computer (e.g. Use a recommended adapter, especially the CC2530 and CC2531 are known to perform poorly. In case you are experiencing an unstable or bad network range you can do the following things to improve your network.
