I upgraded to 0.36 last night, and as soon as I did I’ve been noticing major performance issues – motion/light triggers take upwards of 10+ seconds to activate, when manually triggering a scene it takes up to 20 seconds for all the lights to turn on (and they “trickle” on one by one), or they just never trigger at all.
My setup mostly consists of MQTT “lights” which are actually z-wave switches proxied through a SmartThings hub. Trigger the lights from SmartThings results in instantaneous response. Watching MQTT messages on my network through MQTTlens definitely suggests the lag is happening in Home Assistant.
Checking home-assistant.log (I’m on a Raspberry Pi 3 with the AIO installer), I see this:
