Had chance to do some digging into the delay issues I've been seeing with my #zigbee #tradfri lights on a Tradfri hub, and #alexa. Commands issued to the lights from the Ikea "Home smart 1" app on iPhone work instantly, commands issued from #homeAssistant via the Ikea Tradfri integration are also instant. But commands issued via Alexa and the "Ikea Home smart 1" skill often have a delay of 30s or more.
So, I fired up tcpdump. The traffic's encrypted, obvs, but I can at least see streams...
