Go into Zigbee2MQTT settings and under Home Assistant Integration, check Home Assistant legacy entity attributes. This is a prerequisite according to the blueprint.
But now I get the following error.
Message malformed: not a valid value for dictionary value @ data[‘actions’][1][‘choose’][0][‘sequence’][0][‘choose’][0][‘sequence’][0][‘choose’][3][‘sequence’][0][‘entity_id’]
Any suggestions on where I could start to try and fix this?
