I installed a sonoff zigbee 3.0 stick and the sonoff integration came up. I also want the mqtt service. I am trying to start zigbee2mqtt but I always get an error “Error: Failed to connect to the adapter (Error: SRSP - SYS - ping after 6000ms)”. I have triple checked the port in the config, but I have a theory that maybe I shouldn’t be running zha and zigbee2mqtt at the same time??? The sonoff integration says “zigbee home automation” under the title, so is it safe to say that the sonoff integrations == zha? Am I barking up the wrong tree? Do I NEED the zonoff integration?
Delete the ZHA integration and restart, choose “Ignore” on the automatic detection of the sonoff. Then install MQTT and configure Z2M.
