+
+#### Fixed

+- Added State Class "measurement" to rate_per_time_unit
+- GPIO: Avoid MQTT publishing to empty topic when "MQTT enable" flag is not set
+- Fix timezone config parser
+- Remote Setup truncated long passwords (https://github.com/jomjol/AI-on-the-edge-device/issues/2167)

+
+#### #35 Use the same model, but provide the image from a Smartphone Camera
+as reading the Electricity or Water meter every few minutues only delivers apparent accuracy (DE: "Scheingenauigkeit") you could just as well take a picture with your Smartphone evey so often (e.g. once a week when you are in the Basement anyway), then with some "semi clever" tricks pass this image to the model developed here, and the values then on to who ever needs them e.g. via MQTT.
+IMO: It is not needed to have that many readings (datapoints) as our behaviour (Use of electricity or water) doesn't vary that much, say, over a weeks time. The interpolation between weekly readings will give sufficient information on the power and/or water usage.

 ## Workflow
-The device takes a photo of your meter at a defined interval. It then extracts the Regions of Interest (ROI's) out of it and runs them through an artificial inteligence. As a result, you get the digitalized value of your meter.

See the [documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/#remote-setup-using-the-built-in-access-point) for details.
