Hi,
I did the add-on as stated in “GitHub - zigbee2mqtt/hassio-zigbee2mqtt: Official Zigbee2MQTT Home Assistant add-on”. It should have included two add-ons: Zigbee2MQTT and Zigbee2MQTT Edge. It doesn’t. Anybody know why?
Try a page reload. They should both show up in the addon store. Which one didn’t show up?
Problem solved. I had added Sonoff Zigbee wrong. Took it away and rebooted, now ZigbeeMQTT is installable.
