If you need LQI and RSSI as entities in Zigbee, you are doing zigbee wrong

  • A wise Zigbee developer

That said, I’m doing zigbee wrong. I wrote out some Node-RED flows that consumes the ZHA WS API and then creates MQTT auto discovery sensors with the LQI, RSSI, parent information, etc. Needs a little work to re-do now what zha-map is deprecated though.

    // Find Parent
    var parent_router = {};
    if(map.neighbours.length === 0) {
        msg.zha_map_devices.devices.forEach(parent => {
            parent.neighbours.forEach( neighbour => {
                if (neighbour.relation == "Child" && neighbour.ieee == item.ieee) {
                     parent_router = parent;
