+# Meter Reader
+
+Put a webcam in front of your utility meter and AWS Rekognition sends the reading over MQTT to a MQTT server of your choice.
+
+note: if you restart the addon you will need to update the baseline value.
+
+
+## Config
+
+upd_interval: value in seconds to be used as interval between data refreshes.
+
+url: where to find the picture of your meter (webcam) - it will be stored temporarily in folder /config/www
+
+user: basic authentication for cam
+
+password: password to obtain webcam picture
+
+baseline: current reading of your meter
+
+under: max you expect it to go down during an update interval (where I live solar panels allow meters to run backwards)
+
+over: max you expect it to go up during an update interval
+
+aws_access_key_id, aws_secret_access_key, region: see link on how to set up an AWS account. Did not really see how to get your region, I use "us-east-2" (https://docs.aws.amazon.com/rekognition/latest/dg/setting-up.html)
+
+mqtt_host, mqtt_port, mqtt_user, mqtt_pwd: find and get access to your MQTT server
+
+mqtt_topic: topic on which meter reading gets published
