+# Bluetooth Multimeter
+
+Connect to compatible a Bluetooth Multimeters and display the result on your wrist!
+
+## Compatible Bluetooth meters
+
+Only the OWON is supported right now - feel free to add support for more!
+
+### OWON OW18E
+
+Available [on Amazon](https://www.amazon.co.uk/Bluetooth-Multimeter-Multimeters-Voltmeter-Resistance/dp/B08NJT38SF/ref=sr_1_1)
+
+Turn the meter on, and long-press the Hz/Duty/Delta/Bluetooth button on the right hand side. Now run the app.
+
+## Usage
+
+The app currently only displays the current reading from the volt meter.
+
+If the app fails to connect you'll need to reload it to reconnect.
+
+To exit the app, long-press the button.
+
+
+## Future functionality...
+
+* Logging
+* Graphs
+* More than one meter
+
+## Creator
+
+Gordon Williams (please file issues via GitHub)
