HASS stops responding to triggers; works after a restart

[gpbenton (Graham)]

I haven’t seen this, but I don’t think you are the only one. See this thread:

How much MQTT traffic can HA handle on Raspberry Pi 3?

sometimes automation that uses mqtt as trigger doesn’t trigger. other clients (devices) that subscribe to the same topics can receive the payload just fine. @Andy_Nunes my MQTT broker is on separate computer, not embedded with the HA in Pi.
